The codes that show up are:
P0700 Transmission Control System Malfunction
P0750 Shift Solenoid A Malfunction
This problem has happened a total of 3 times so far, with two of those times happening just before Christmas, and the other just today.
I did a trans fluid & filter change using the +4 fluid, after the first incident, and changed the Solenoid pack after the second time.
When this happens, I can turn the car off while rolling (or stopped) & restart, and the trans will shift normal - even with the check engine light on solid.
The solenoid pack is a new part from Borg Warner, and since it is doing the exact same thing, I have to say the problem is somewhere else. I just ordered a TPS for the car on the off chance that there might be a dead spot on the film, (very small possibility as this type of sensor tests into the 1 million cycle range - but still possible).
I figured for $30.00, it was worth a shot. The only other part I can think of that could be causing this is the computer, which is $300 for a rebuilt unit.
Have you run into this before? Any ideas as to what might be causing it?
This is currently my daily driver, and it goes about 80 miles a day - 5 days, so I need it to be reliable. It has been great for over a year. Trying to get it to go some more.
Ironically, I used to work at a transmission shop in Flint, Michigan, but that was before all the electronic shift solenoids came into the picture. Worst electrical issue we dealt with - LU solenoids crapping out - no big deal.
Any advice would be very much appreciated.
have the same problem?
