A998 to 904 Trans swap????

[fastcorgigarage]

I have a 87 Ramcharger with a bad 998 trans and I have a 76 Tradesman with a good 904.

My question is can I take the 904 that is behind a 318 and use it on my Ramcharger (also with a 318) in place of the 998? I don't plan on hot rodding the SUV I just need it to get back and forth to a job.

Before it is suggested I cant afford to pay a trans shop to rebuild the 998, and I have tried to rebuilt a trans before only to have it end horribly.

Should work but you will need a drive shaft.

The SUV has a wheel base of 106 inches and the van has a wheel base of 109 inches, so will I have to have one of them modified to a correct length or will the van driveshaft work?

Is the Ramcharger 4wd? Tradesman is a 2wd motorhome, correct?

Both are 2wd. The van is a full sized van sitting on a truck frame. I know for a fact the van pulled a camper behind it through the Colorado mountains with no problems.

904 and 998 are basically the same trans 998 has lower 1st and 2nd gears and more clutches you may want to get the torque converter from the 76 should be non lock up your 87 may be a lock up you should be able to use your 87 driveshaft transmissions should be the same length
