90 Cavalier
transmission problem?
Q: I have a ‘90 Chevy Cavalier with a 2.2
L and auto transmission. On short trips the car is fine. But on long trips,
or hard city driving when the car gets hot, as I slow to a stop the car
shudders, and jerks very pronounced, then stalls. It’s almost like having
a manual transmission, and trying to stop while in 4th gear without putting
in the clutch. The car will immediately restart in neutral but quits as
soon as it’s put in drive. I have to either let it cool, or drop it into
drive 5 or 6 times while trying to feather the throttle. I plan on changing
the transmission fluid, but I've been told it sounds like it could be
the TCC solenoid. If so, where is the solenoid located, and how difficult,
and expensive of a repair would it be? Is this something I can do myself?
The car is a high mileage work car that has been very reliable, but I
don't want to sink major bucks into it.....Mike
A: You’ve
described a sticking lock-up torque converter solenoid problem perfectly.
A replacement solenoid is not that costly. This condition can be easily
proven by disabling the power supply to the lock-up solenoid and driving
the vehicle. I would not recommend replacing the solenoid yourself unless
you’re reasonably comfortable working on transmissions. In any case it’s
not big bucks in parts or labor.
