1997 Qx4 Transmission RE4R01A

[mkimister2]

I searched but could not find anything on it, but I am swapping my transmission to a remanufacted one and the transfer case is not mating completely. The splines are correct and it goes on to the output shaft, but needs to go another 1/2 inch. I tried to bring it in by tightening all the bolts equally, but did not want to force anything so I stopped that. The measurements say the shaft should slid in all the way, but for some reason it is not. I was thinking maybe the shaft might be too long. Were the 2wd and 4wd transmissions the same (part numbers)? Are the output shafts the same length? Any help is greatly appreciated. I really need to get the car running since it will be my daily driver. If they are the same, then why would mt transfer case not seat correctly? Thanks, Andrew

Heres the transmission's part number.....

To summarize, it looks like the 97-99 were the same..... Even though they have different numbers i doubt theyre different... However they do make clear differences between the 2wd and 4wd later ones.

To add to this, the torque converters were the same from 97-99 but changed in 2000...

Do you know why the transfer case would not mate flush with the adapter case if the transmissions are the same? I know on my subaru the clutch fork can lock up the trans to engine, can something be similar on the transfer case? Thanks for the help so far, Andrew PS Sorry about the double post

check and then check, and then check again to make sure that the torq convertor is completely seated in the pump. if they don't line up just so, it will cause that 1/2 inch gap like you say. smart to not force it--20+years ago i failed to heed the warning and kept cranking on it until it seated--with a big pop--which i foundout after it didn't work and disassembled the whole thing was the pump gear bursting.

Well I went into the garage tonight to do all the math to figure out with is wrong with me or the transmission. Seems to be the transmission output shaft is about 1/4 inch too long!!!!!!! Here are some pics to show what I mean:Here is just a picture of the whole setup assembled, transfercase is not bolted for obvious reasonstook off the adapter case to measure, length from trans to TC is 6.75 "Length of the adapter case is 6.5" plus 1/32 for the gasket

If my measurements are correct which they seem to be otherwise I would not be posting, how dificult is it to change the transmission output shaft(probably a nightmare)? Is their a solution to this problem? Is there numbers on the transmission that would let me know if it was a 2wd or 4wd(I could not find a vin)? Why did Nissan/infiniti make the shafts different lenghts especially only 1/4 of an inch, or did the rebuilder make a stupid mistake ? Any help is greatly appreciated. I really need to get the qx4 back on the road. thanks Andrew

Anybody???? Or does it look like I am going to have to send it back?

well, i didn't help you too much last time since i didn't read to see you were on the output end and not the input end.....but, if the output splines are starting to mesh (correct number of slines, etc. then i'd check for obstruction in the recepticle of transfer case shaft. seeing the splines sticking out a bit seems supect (why doesn't it fully engage) do you have your old trans to see if output shaft lengths are the same? it does not appear that the outputshaft is mis-installed, due to where the park gear is at. could be the output shaft splines are gouged up or something that is preventing full ingage to the transfer case.
