93 850 glt transmission issue

guest · Post by **guest** » 08 Nov 2003, 10:57

If I start my glt and let it warm up in place for more than 5 min the transmission arrow begins to flash and the car locks in gear. The next time I drive it the car functions properly, however the light remains flashing. The next time the light goes out and all is well. I have tried this a number of times and verified this sequence. All this seems to have developed after a tranny flush.It was done by my regular mechanic and re checked afterwards.
any ideas?

Oh come on, someone has to have a thought or theory. I'm out of ideas on this one.......Iam worried about getting stuck this winter... Should I be concerned?

Get the code pulled from the computer. That will tell you where to start. The flashing light is a trans problem - sorry. Do a search on the "arrow" or "transmission" and check out the threads on other trans issues.

I replaced my trans about 2k ago. I wnt through multiple flushes in hopes of flushing the problem away.

Good Luck.

if this developed after tranny flush, u need to check fluid level and its possible bubbles could have formed inside, fill it up to the top hot mark when hot (check when temp at 3 o clock)
