Jim Grant's Tech Tips
Chevy Berretta, Short Trip Car
I have an '88 Chevy Berretta that goes dead after you drive it 15 miles.
After 15 miles it will crank but you put it in drive and it stalls. If
you wait 30 minutes it will start and go another 10 miles, put on the
brake and it goes dead again. It will idle all day long and never go dead
or get hot. I put on new coils, sensors, changed computer, battery. please
most frequently seen cause for your problem is a sticking or gummed up
torque converter lock up clutch solenoid. The ALLDATA Information System
shows GM's Technical Service Bulletin addressing this issue. The fix requires
an updated solenoid and transmission fluid replacement. An easy way to
verify this condition is to have your technician disconnect the electrical
connector for the lock up torque converter solenoid and then drive the
car. Due to the age of your vehicle it may be that the solenoid is just
plain worn out, needing replacement. And just think you won't have to
worry about any of those other "new" parts failing.
