I just replaced my tranny in my2002 maxima gle. Its an automatic and the tranny came out of a 2003 maxima. The tranny had 16000 miles on it well so they say but the fluid looked great. I got the tranny in and put in a stage one valve body from maximum tuning while i had it out. Got it all ready to drive and it was a disaster i only had 2nd gear and reverse would kill the car when i put it in reverse. So I took the pan off and checked the valve body and i discovered i didnt plug it in doh! So i plugged it back in and put it all back together and it was a little better. I still had first but in drive it wouldnt shift out of first. Then i would put the car in second let off the gas completely and let the car find 2nd. Then after it got into 2nd i would get up to about 5k and try 3rd without any gas and it would find it eventually but if i gave it any gas it would jump out and go to 2nd. I did the same for drive as it did for 3rd.
So i took the pan off and put the stock valve body back in. It is alot better but there are still some problems. Drive will pick up first and take off like normal but it will not shift to second. So i put it in second and let off the gas and let it find second as soon as the rpms indicate it has went into second i give it gas and its fine. Then i put it in drive and it will find third and forth fine but it seems like when i give it gas it doesnt really now what to do sometimes it will jump to 2nd and sometimes to 3rd.
My check engine light was on at this time so i went and got the codes and there is alot.
p0740,p0745,p0750,p0755,p1760, and p1574!
This is what the parts store told me
P0740, Tcc Circuit Malfunction
P0745, Pressure Control Solenoid A Circuit Malfunction
P0750, Shift Soleniod A Malfunction
p0755, Shift Solenoid B Malfunction
p0760, Manufacturer Control Transmission
p1574, Manufacturer control vehicle speed. Idle speed control aux. inputs.

Any help with this would be greatly appreciated and if anyone would know what to do i believe the peeps on this sight would know what to do.

sounds like your tsm is having some trouble(would explain the misshifts and such) check connections, you may have damaged it.

Do u think the solenoids went out or its just the tcm acting up? I think it is the tcm because I left it unplugged on the first install maybe it short circuit itself in the fluid?

All of those codes sound like they are there from not having the selenoids plugged in originally. I would reset and go from there. Also, maybe the o-rings from VB to housing are having problems? I hate to say it, but if all of that checks out it's very possible a problem with that valve-body or valve-body install caused no line pressure and instantly smoked the **** out of the clutches in that trans. I've been there, done that

I reset and the codes came up immediately. I forgot to plug in the solenoids on the first try. They are plugged in now and same prob. I think im gonna get another tcm and put it in and see what happens. If i still have problems then im gonna put in new solenoids.
