I just picked up my first TD and it has a rebuilt 525 from a TBI car. I know that they werent the same as 525's from a TD, and I came across a 523 from a 94 shadow non turbo car and I need to know if its the same internally as the TD cars before I go spending money on it.
All 92+ 523's are the same internally. All came with 3.77 final drive. I just picked up a 80K mikle one from a 94 Shadow for $85. That was with salvage yard pulling it for me.

I think the only difference in the early 523s is the FD options. I don't think they ever put a 3.85FD on a turbo car. I think they did offer both the 3.85 and 3.50FDs in some NA cars though so it makes the 3.85 FD more rare but it really isn't very desirable anyway.

3.85 was used in the minivans for the first 2 years.Quote:

Also, 525s were same for turbo and non as long as the FD ratio was the same, AFAIK.
I have even seen NA shadows with the 3.85 FD but like you said they were only available in the 1st gen 523s.Quote:

Some one can correct me if im wrong, but the 525 trans is 18 spline input and the 523 is 17 spline input. You would have to change the clutch as well.Quote:

The 525 is a hand grenade waiting to go off btw.. I have a friend who nuked one down shifting into 4th to pass on the highway..
yes this is true. turbo van would have the 568 3.85Quote:

rich is right. all gearing is the same within the 523 trans (90-91), just FD changes between n/a (3.85) and turbo cars (3.50)
the 523 92+ trans has a different gearset then the earlier A523 (90-91)
it is also stronger, and the gears are lengthier like the A568 gearset. im almost positive that any 92+ 523 trans had a 3.77 fd (turbo n V6 for sure....not quite sure about the n/a trannies)
the A523 92+ gearset combined with a 3.50 fd is another hybrid option for those who cannot get ahold of a 568 trans ;)
short answer. NO its NOT the same. however complete trans will bolt in like butter. you will need a large spline clutch tho. a turbo pressure plate would also be ideal!Quote:

youll need 2 mod the driver side trans bracket to get it to bolt up to the 523, just a little grinding and your good 2 go!
I have a 92 523 that seems pretty bulletproof in my Charger.
I also have a 90 523 that was no so bulletproof, but had the 3.50 gear that I put in my 92 523.
That combination is really good, although not quite as nice as a 568 with a 3.50.
The earlier 523 tranny did have the 18 spline, small input shaft. The 92+ has the larger 17 spline.
Cables are easy - L-body, make sure you get P-body cables. You'll also need the shifter from the same car.Quote:

I'm getting the trans, shifter and cables all from the same shadow, if the guy ever answers his phone...
I knew about the axle swap, but thanks for the info on clutch splines and mounting. I was planning on running a pressure plate from a Spirit RT because they have a higher clamp force, will just use a stock clutch disc i guess
yep:thumb:Quote:
