Car Forum / Driving, Maintenance, Tuning / General Car Topics / July 20081988 Chevrolet Celebrity Stalls
Get the car up to about 30 MPH, come down hard and constant to a "rocking" stop and the engine stalls and dies. Repeat the procedure but place the car in nuetral prior to braking and the engine does not stall. One shade tree mechanic says the fuel pump is bad. My guess is the tranny is the culprit. Your thoughts please. > Get the car up to about 30 MPH, come down hard and constant to a "rocking" > stop and the engine stalls and dies.

It is a small electrical parts under the side pan in your trans. Parts and labor appx $250 by a good technician.

This is the same solenoid used in earlier Buik Dynaflo trans and is a known piece of crap. Look for the wire plug going into the trans at the end cover (sheet metal pan mounted vertically - top corner between fire wall and trans. Disconnect this plug and try your test again. TIE UP the plug - DO NOT let it just flop around. P On Jul 11, 7:20 pm, cse...@mts.net wrote: > >This is caused by your torque converter lock-up solenoid failing to > >release.

In my experience they release when you shut the key off, then work normally for a while before acting up again. > Look for the wire plug going into the trans at the end cover (sheet > metal pan mounted vertically - top corner between fire wall and > trans. Disconnect this plug and try your test again. Have you tried this?

It's a good way to confirm or discount the solenoid as an issue. Most of all it cost nothing except for your time. It also occurs to me that thickened dirty trans oil will do the same thing. Think about dumping the oil and replacing the filter in the trans pan. I'll guess the trans has not had service for some time. P |
