s2 keeps blinking in drive

i have a 4 door 90 ls auto and when i shift into drive sometimes it blinks and sometimes the s2 starts blinking anyone know what that means and how to make it stay off

Your transmission has some pretty serious problems.

Get it to a good shop ASAP.

I believe on auto trannys, the S2 blinking is warning you of something possibly damaged or something of that nature, that is out of “whack” with the tranny. Usually if nothing is wrong upon startup the S2 light would shut off. Thats what i remember when I owned a auto teg, check your booklet

i dont have the book and its only sometimes or sometimes the d will just flash it never happens on startup always after i have been driving around for a few i am getting code 7 and 8 do you think that would effect that im just going to reset the car and go from there also the tranny shifts really smooth and quiet

I know of s3 and s4 what the heck is s2… and I have an AUTO too :auto:

i meant s3

you need to read the trouble code from the tranny computer by your left leg. then you can run through the troubleshooting steps in the service manual. there was a long thread covering this (with no good news in the end)…

i reset the ecu and has not blinked since
