SRT4 Trans?

[dodgeshadowchik]

Hey all you 2.4L guys!

I'm planning on a 2.4L swap with the blue shadow I have. It was brought up at SDAC that parts for the older TD transmissions are getting harder to find. So I was thinking of just using the NV-T850.... however I know its hydraulic so I'd have to figure out how/where to mount the master and slave cylinders. My other question would be could I still use the shadow shifter or would I have to somehow get the neon's shifter to work?

I really don't know much about that trans other than that it's pretty strong. If anyone could point me in a direction that would be cool! Heck, for all I know the thing may not even fit!

Thanks!

it will fit, but it isn't fun from what i understand. the shifters are pretty close, so it could be made to work, but mounting a master for the clutch will be a pita. i used a 568...it is supposedly stronger anyways.

the downside to using a 568 with an srt 2.4 is that the srt has raised oil drain ports in the rear, and the nvt mounts the starter up front, so you have do some grinding on both the block and starter to make it fit, and the oil drain is very much in the way, so it needs to be moved, or do like i did and shorten it a lot and the silicone will just barely clear with a tiny bend, but no so much to kink it. and of course, you'll have to make custom mounts...

Yea, the 568 is my other choice if the 850 doesn't work. Thanks for the tidbit there!

It was a toss up between T850 and A568 for me. I mostly went A568 cuz the gears are a little longer and the T850 has some high RPM shifting issues.

K. I guess I'm scared of blowing that 568 and not being able to get another one!

meh if you blow it up (will need over 500hp) a568s are $6,000 a dozen.

You could always run a 3.77? FD 523. They are nearly as stout as a 568. I believe one of the Ramsdels posted pics of both gear sets and they look pretty beefy.

Do you have any pictures of this?

I have the SRT block and I thought the drainback looked very tight... Perhaps I will just tap and plug it and then go with a drainback line to the oilpan.

Is there any chance that you have a picture that illustrates the grinding on the starter and block?

My 568 already has an OBX and 3.77 gears so swapping to a T850 or built up cable operated 350/578 seems like a waste.

Plus I just had the custom dust sheilds made for using the 568 with the 2.4 engine.

Thanks,

Rich

Yeah what is up with those shifting issues. Local 600hp srt-4 here cant improve on his low 11's (ran almost same times when modified stage 3) because he cant shift above 6300 rpms or something like that. His solution is a lighter twin disc clutch.


Ive never heard such a problem with our older transmissions, and I am pretty sure people have shifted well north of 7k in them. I know if I was building a 2.4L I would be taxing that high RPM power.

[BadAssPerformance]

The high rpm shifting issues are because the T850 is based on a european diesel minivan trans. How many diesel engines need to shift past 3k rpm?

[dodgeshadowchik]

Thanks, I think my mind was just made up! I'm going to stick with the 568.

LMAO, what the heck were the daimler fools thinking.. Selling a car like that with a trans based on that engineering.. I vote 568 all the way.

You just wanna be like JT

That may be....

I haven't weighed a T850 myself and don't have any way to verify it but I have seen several people mention that they weigh nearly 200lbs....

Doesn't the 568 weigh more like 100lbs or less? The following post gives a shipping weight of 110!

My OBX was 6lbs heavier than a 2 pinion diff but probbaly even less of a difference from the the 4 pinion diff....

That alone is a pretty good reason not to use the T850. 100lbs is a pretty serious difference!

holy crap! That's like the dsm trans. The Talon's manual trans is on heavy SOB.
Thanks again guys for all the info. I find that both have pros and cons.... but it seems the older TD transmissions are looking like better options.

Do you have any pics of this clearance issue. I haven't got my motor or trans, I my just build a 2.4l if the drain and feed lines in a problem

[t3rse]

I'll see if I can find some pics. All I can say is that it wasn't very fun....

DSM manual is just under 150#, 568 is around 120#.

[dodgeshadowchik]

cool, thanks!

[t3rse]

Sorry folks. No pics. I don't see myself getting motivated to pull the starter out to snap pics, but if something happens or if I cook it (which I probably will shortly) I'll make sure to take some.
