Hey all, im getting fed up with my TH125, it revs high on the highway, it is full of problems, it has to go! I do not want to spend tons of money, and I want to do a quick swap of the transmission (hopefully without dropping the cradle) and I am wondering, how hard it really is to swap the 125 with a 440... Can all the stock mounts be used? axles I need? What does this all entail? Also, is it worth the time and money? I already found one 440 at a local scapyard for 175 bucks.

Basically, answer this please:
How hard is the swap?
How long will it take?
Custom fabricated parts?
Axles?
TV Cable Usage? (mine on the 125 is broken where it goes into the trans, can I use the one off of the donor vehicle? or use the 125's after trying to fix it?)
Final Drive & speedo calibration?

The one I found is out of a 1992 Chevy Lumina...

Here is some reading to get you started.

Thank you! I will read up some. I hope its not too hard to do in one weekend :P

Quick answer. It will bolt up. Use the 4T60 mounts (redrill them to fit the Fiero cradle mount positions) , use new axles. (I believe that Pontiac 6000 axles that used this trans are a direct fit) . reverse and modify the shift arm and run a vacuum hose for the modulator.

Plan on dropping the cradle if you want to do it the easiest way. There is just no better way to work on them.

Thats the swap I will do pretty soon. you say the cable is broken on your 125, And you having problems ? who would have guessed
