Neon transfer gears?

[cordes]

I have a 97' SOHC Neon and would like for it to turn less RPMs on the freeway. It's really flat around here so I just don't need to be turning 3K RPMs at 70mph.

Now, I've heard that these transfer gear deals are easy to change and would drop my RPMs if I use the right ones. Which ones do I need? From what car? Are they really that easy to install? What would be my new cruising RPMs at 70MPH in 3rd?

[contraption22]

From the Dodge Garage.

There was a variety of different gear ratios & transfer gear sets made for the 413 over the years from the factory, a few of them are listed in the Mopar Performance catalog or you could just go digging in the factory parts books to find a combination that suits you.

Transfer gears-

0.91 (52 and 57 teeth) (later L body)
1.04 (47 and 45 teeth) (Neon)
1.22 (60 and 49 teeth) (early L body with the VW)

In the factory service manual the following possible stock final drive ratios are listed:

2.60 => 0.91 transfer and 2.86 ring
2.78 => 0.91 transfer and 3.05 ring
3.02 => 1.06 transfer and 2.86 ring
3.22 => 1.06 transfer and 3.05 ring
3.50 => 1.22 transfer and 2.86 ring
3.72 => 1.22 transfer and 3.05 ring

And for Neons:

3.19 => 1.04 transfer and 3.05 ring
2.98 => 1.04 transfer and 2.86 ring

[cordes]

I beleive neons have their own transfer gear ratio, which were not available on older TM's.

You would need to swap in the .91 transfer gears for a lower ratio.

So I need to get them out of an older car like ours? I read that some guys are using the gears out of a later L body?

ETA: Using the ones out of a later L to lower the FD numerically.

[contraption22]

I think you are correct....

[cordes]

This is going to be great. Now I just need to crunch the numbers to make sure I won't go too numerically low with the FD. Well, I guess I need to figure out what they really are, how they work, and how to change them too. :p

I'm going to be a trans master by the time I done fooling around with these cars.

[ShelGame]

Transfer gears are actually pretty easy to swap. They're under the LH side trans cover, you can swap them with the trans in the car and the LH front wheel off. Jack the car up enough so that no trans fluid leaks out and you're golden. You'll need a big breaker bar and a torque wrench...

[bakes]

or a rag and impact gun , put the rag betweeen the gears and nail it with the inpact to get them off then use a gear puller and use tread locker!!!!

[Speedeuphoria]

use red loctite

I dont know how they figure 3.19 when 1.04x3.05=3.17 but thats what you got prob actually what I'm running currently.

Easiest would keep your ring and pinion and find some .91 gears (Simon has some but price went up)

That would give you a 2.78 highway gear, should be OK

[cordes]

Wow, this sounds really easy. Thanks guys!

Just make sure when you do it, you grease the bearing spacer in place, if you don't get it seated correctly, it can be a mess.

I do have some .91 gears for sale, open to a decent offer, :nod:

You also need brake cleaner and RTV for the cover. If you have a Neon, you have the updated nut retainers so if you don't get them tight enough, they won't come loose.

You will need a harmonic balancer puller for one of the gears.

I paid $75 plus shipping a few years ago, couldn't find any, anywhere. They are rare around here and unless you have the tranny numbers from Rob's Korner, its basically check until you find them. The .91's are supposed to be only in L body's, the 1.04's in Neon's and the 1.22's in early L body's and VW's. Sure you have the right ones?

[cordes]

It looks like the .96 gears will get me down to 27xxRPMs at 70MPH. That's about 100RPM more than the .91 gears would be at the same MPH. I can live with that for $5.

I looked at them today on my way to get some parts. It looks like there is virtually no difference. :confused2:

My math must be way off or something else is afoot. Would changing the transfer gears mess with the lockup converter? I just took the car up to 70MPH and it was turning just over 3K. It is turning right about 2700 doing about 62.5MPH. I'm not too happy with this one so far.

No, if its locked up, it acts like a regular clutch, so it relies on gearing.

Interesting, what teeth count do you have on the old gears?

MY .91's made a big difference, even without LU.

My van in LU is turning around 3K at 60 mph, around 3500 at 70 mph with the 3.05 gearing and slightly taller than stock tires.

I counted the teeth on the gears that came out of the trans. They were 47 and 45 teeth. That's the stock 1.04 Neon ratio.

I'm pretty astounded that this has done nothing to my RPMs. I guess I need to look at the math again.

What if they mixed up which gear is which in the 56/54 math. If the driven gear is actually the one with 56 teeth, then it would make it a 1.037 set. Round that to 1.04 and you have the same multiplier for the FD that the stock Neon transfer gears have.

Honestly, I think that the output gear is the one which had 54 teeth on it. So that would explain why I'm not getting any better situation RPM wise. :mad:

Ok, looking at my .91's, looking at the top side of the gears, so that's with the bearing's on the counter, the flat gear is the one that goes to the pinion shaft, the dished one is the drive. So in my case, the dished gear has 52 teeth, the flat gear 57 teeth. You divide the dished gear into the flat gear, so that's 52/57 equals .91. Hope that helps you determine which way to divide the teeth you have.

That would make sense as you got your gears from a Shadow, and the older units didn't have the .96 gears, AFAIK.

Thanks Simon. I didn't actually do the math when I searched and found that on .org the other day. Now that I have done the math they must have it backwards. You divide the driven gear by the drive gear which is right, but they have it labeled as 56/54, drive/driven when in actuality it is 54/56 drive/driven.

If I'm not working on Thursday I'll head back and see what I can find. There are a ton of auto cars there so surely one of them will have the right gears. I've seen guys posting up about finding them in plane jane cars so that should be easy enough.

Having actually done the math it does reinforce the idea of swapping to the .91 transfer gears though. It will make a huge difference in gas mileage.

The SOHC cars came with a 2.86 ring which is what I have. The DOHC cars came with 3.05. I wonder if you could take the 2.86 ring out of a SOHC neon and use that?

Sure you can.

I have the 2.86 gear ratio, so with the .91's, your at 2.60.

I wonder if mine isn't the 2.86? would make sense as my RPM seems to be higher than everyone elses, :(

[bfarroo]

With a DD auto car the 91's are the only way to go. I can get 31-32 mpg in my spirit cruising at 60 which is pretty good for a auto. Bump the speed up to 70 and I'm in the high 20's. With the 1.06 gears it always seemed like the RPM's were just to high. I can still punch it half way through an intersection and break the tires loose easy. I can get 50mph out of first gear. I'm sure you'll notice some improved mileage in the Neon with it's light weight and aerodynamics compared to a spirit or van.

If your is the 3.05 ring gear, the .91 transfer gears would put you at a 2.78FD.

With a 205/60r15 tire that would look like this...

I could get you everything you need. Do you care what color the switch pods are? Do you care if you have to solder a new section of wire to the two ends at the connectors? It is way easier to pull them that way.

i have black pods.

i just need the clockspring, the actuator lines and vac reservoir, and connectors/pins.

shoot me a PM and we can work something out.

Thats probally what mine has the DOHC auto.Its a freakin Dog down low.Ill have to find some numbers on the case to check.

[Aries_Turbo]

my wifes DOHC atx is a super dog too. its stock.

Brian

[cordes]

From what I've read the DOHC cars are real rev happy and probably wouldn't like an auto down low anyway. The DOHC cars turn crazy RPMs at highway speeds with the auto trans. IIRC it's close to 3800RPM at 80MPH. That's worse than an GLH.

By the way, does anyone have any dyno graphs of stock Neons? I would be interested in looking at any of them available so long as they list the mods or lack there of.

they may be rev happy, but the computer shuts them down way too early.

just as it starts pulling hard, it shifts and the falls back into the range where it isnt making good power.

why they paired that screamer with a tall --- atx, i dont know.

Only one I have is Turbo'd and I dont have a scanner.I did dyno my 98 R/T a long time ago and it made a whopping 123@wheels but went 14.73@89.

Thanks for that info. I'm interested in the torque curves for the stock SOHC and DOHC motors. I would like to fine tune my cruise RPMs with tire size.

Please do. While it's pretty easy to figure out, a set list would be nice. It would have been great since I installed a 1.04 set out of a shadow on account of someone else's error and my lack of knowledge at the time.

I don't think the 1st page has the nut size. They are 30mm. A 32mm socket will work in a pinch though. :eyebrows:

I used the puller piece out of my harbor freight bearing splitter tool kit and two caliper bolts out of a stratus which are the same thread as the gears.

[bfarroo]

Pulling the gears was pretty easy other than they like to pull the wheels off the cars and then set them in the mud so getting the plastic guard off the omni was a pain. I pulled the cover, then used my cordless impact to loosen the nuts on the gears. The two bolt holes in the omni gears are 6mm bolts while the later TM ones are 8mm. My pulller kit didn't have any 6mm bolts I ended up finding a set of 6mm bolts holding the coil on a 93 shadow. I got them installed on the car after clearancing the case but I don't like how much of a offset there is so I'm going to order a new bearing and get a spacer to offset the gear out and see if I can get a little machined off the front of the gear to get more thread engagement with the nut as I've heard it's close.

[skitzo_inc]

I'm curious as to what MPG you are getting right now, Cordes.
I have an 04 SXT five speed and I pull between 38-45MPG at 70MPH depending on crosswinds.
I'll have to check on my RPM's this weekend when I go home.

[elle bawdy]

If I'd kept the .91 gears, I figure it would have dropped me at least 500 rpm in LU mode, they were worth 300 or so with a regular converter.

.91's dropped my rpms 500 in my 89 turbomini, non LU. Was running 225/60-15, mpg noticeably better. Great mod!

Thanks for the feedback.

As a longer term update I'll say that it was a great move installing the .91 gears in our omni. We are getting the same MPGs at 10MPH faster freeway speeds.

Add in the tow truck miles, bet that bumps you up to 30 :D

cordes, just wondering if you found you have to go 10mph faster to get the mpg now.... sometimes can happen like that due to where in the efficiency range of the motor you're driving and how much you load it.

It isn't a must that we go 65-70 now, but if it's really windy as it can routinely be around here we won't lose any mileage by going that 10mph faster. I'm looking for a 95' cam to put in it to hopefully help it out power wise in the cruising range.

If yours is anything like mine, it'll downshift into 2nd and it won't make that much of a difference anyway.

I'm on the lookout for a magnum top end for mine. Guys on the .org are claiming some pretty impressive gains by swapping.

[Aries_Turbo]

mine will downshift to 2nd and then hold the gear till 60+mph cause the kickdown lever is sticking lol.

i gotta pull the valve body and clean that up. its happened to more neons than i can count in this area of NY.... salt heaven.

Well, before this tank of gas I finally replaced the bad O2 sensor which has been in the car for a long time now. I think it finally crapped out for good around the time I installed the gears because on this tank I think I'm going to break 40mpgs with ease. It's been a little city and highway too. I'll report back when I get the final word which should be tomorrow if I had to guess.
