Since the search function doesn't work I am having trouble finding information on AT problems. Out of no where my tranny has started to slip. It started with a fourth gear malfunction code (1106) and now I am getting codes from 1203 overrun clutch solenoid, 1204 Torque converter clutch solenoid, 1205 line presure solenoid, just a few days later. Under the ECU code descriptions in this forum, http://forums.maxima.org/showthread.php?t=235667, the links to these threads are unavailable due to the disabled search function. PLEASE HELP

 

I was wondering if this is simply a vavle body or solenoid malfunction or if there is deeper damage in the tranny. Also, the fluid level is high and I have had this symptom in a passat when the transfercase leaked gear oil into the AT contaminating the atf fluid. Does this happen in Maximas? Could that explain? What causes such catastrophic failure. Can I just replace the valve body, solenoids, or do I need the whole tranny swapped? Once again, please HELP!!!!!

 

Could be just a failing valve body. Jack the car up and drop the tranny pan. If the fluid, magnets and screen mesh filter are full of metal parts your tranny is shot. If it's pretty clean you might just get the valve body rebuilt or exchange it for another one.

Being your getting all those codes, it does seem like it's an electronic issue. The ECU cannot detect mechanical failures - you might be lucky!

The tranny and differential are housed in the same unit and is lubricated by the same fluid.
