A340E automatic transmission
I bought an 89 toyota supra turbo a while back with an automatic transmission. Ever since I got it I had a problem with the transmission. When I would put it in D (drive) it would start off in 3rd gear. If I shifted it manually it would go from first (in L) to 3rd (in 2nd) to OD (in D). After months of chasing the problem I finally found the culprit. The shift solenoid (S1) was stuck. I pulled the solenoid out of the transmission and hooked it up to the battery to make sure it was functioning properly. I also used compressed air (low pressure) and cleaned out all debris. When I put it back together it ran like a champ. Hope this helps... Good Luck!!!
