Can anyone tell me if the a-904 and a-500 have the same pan. A friend of mine has a bad a-904 with an aftermarket deep pan, and he said he would send me the pan, but i dont see any point to getting it unless it will work on my tranny. My wife says i already have enough parts laying around that dont go to anything we own, and i dont need any more. My truck is a 1991 dakota 4x4 with an a-500 automatic. Thanx for your help.

 

I would take a look at it if you can, or get measurements on it and compare to yours and see if it's going to work

 

I will have to have them measure it. It is at a friends over 4 hours away.

 

The bolt pattern is the same. But the 500 has a extra deep pan to accommodate the extra overdrive valve body.

 

Thats what i have heard from a few people, and that as long as the one he has is deep enough, it should work, but i am going to have him measure the depth tomorrow and let me know.
