BadAss SRT-Z - 2.4L / A568 - Update!!!

[MiniMopar]

Interesting... each 87 car I've owned came with damn ATF

BTW I think the junk in the oil is OBX grey matter, LOL

Just to make sure my age hasn't caused a brain fart, from the 87 FSM, in the section titled "A-520 Improved Front-Wheel-Drive Manual Transaxle":

"To reduce wear, the manual transaxle now uses SAE 5W-30 engine oil as the lubricant."

I also remember the first time we pulled the axles out of my dad's 87 Daytona and saw engine oil come out. We though the ATF was burned or something.

1st gear side before the last Surgery



2nd gear side before the last Surgery



During sugery I flipped the 1 and 2 sides over to put the "good" side on 2nd. Took thecar out and made 2 passes, both misisng 2nd gear.

1st gear side (formerly 2nd) after the 2 passes.



2nd gear side (formerly 1st and smooth) after the 2 passes.



So yeah, it dont take much, but these were the soft brass thast similar harness to the OEM plastic pads.

As for why its uneven? Hold the fork and rod try to move them relative to each other. They pivot on the roll pin.

Can o' worms. But, I have heard some say that synthetic motor oil might be too slippery for the syncros.

Think about what you just posted and tell me if you think it makes any sense.

As soon as I heard it and thought about it, I dissregarded it as I've never found it to be a problem. I've also been running Mobil 1 10w30 in the Charger for over 5 years with Zero failures.

The Mopar 2.2L Performance Manual actually says the MTX uses ATF, 5W30 and 80-90 Gear oil in different places in the book.

I'd have to look back to be sure, but I'd swear I read 5w30 for a street driver, 10w30 for a wknd warrior and 20w50 for a drag car.

I'm not sure what you mean. I don't know if it is true in this instance, but I can certainly see how it's possible. There needs to be a certain amount of friction for the synchros to do their job.

Edit: RedLine claims this in their sales literature.

the stiffness and hardness are key and you would have to get pretty exotic with plastics (like PEEK) to get the hardness I want.

.....That's what JT said!

I think I know what you are saying here.....but shouldn't the rod and fork be a really really close fit, and the roll pin there just to keep them together?

Sounds like the shifter fork has gotten hogged out. Time to repair it with some kind of sleeve or find another one. The thing is rock back and forth as your shifting gears, that is why the pads have worn funny, IMO.

I hear what your saying, but I can't get over thinking that two objects trying to mesh with each other can only benifit from better lubrication. Anything that would put a "drag" on them would also cause them to drag wile trying to engage one another.....no?

If I am correct, the friction of the synchros helps the dogs engage easier because it gets the dog teeth moving at the same speed, or close to it before they are engaged. So if there is not enough friction, the synchros will not functon properly.

The friction of the stop ring on the taper of the gear is what you are talking about. And yes, you are correct.

OK, I can see that, but shouldn't the tapper take care of that?

I guess like everything else, it's give and take. You put in a higher friction oil to get the synchros to work better and what does that do to wear and tear on the rest of the parts?

[onerippinturbo2]

i too think you should source another shift shaft and fork, if the fork is wobbling on the shaft, that is most likely the cause for the uneven wear and can't be helping the missed shifts either. now i know it is going to be tough locating these, did you try rockland standrad gear in new york? i would give them a call, they bailed me out a few years ago with a 555 that i did for a friend, the forks were NLA then too. they had everything i needed at the time. wouldnt hurt to try.

[Reaper1]

Screw it...time to go to either a Quaife or Xtrac tranny! LOL!!

Yeah.. might need to be bushed.

[BadAssPerformance]

OK, swapped a fresher 2nd, 3rd and 4th gear onto the mainshaft tonight... also a new looking stop ring for 2nd

THANKS AGAIN Dean for the spare parts

[22shelby]

ok sooooooooooo RSD for a shake down?????

[BadAssPerformance]

It's not together yet...

good luck man, win some cheeseburgers!

[BadAssPerformance]

Decided to use a little "TIG glue" to keep the race on the shaft.... new 1-2 pads... will start putting it all back in tomorrow after work.

[turboshad]

New pads as in bronze or new brass you had left over?

EDIT: Nevermind......I read the other thread.

[BadAssPerformance]

No problem... if you look close they are a different color too
