The transmission will not downshift to first. Appears to use third gear only unless you manually downshift, then it goes to second gear. Indicates codes 1,2,5,7,8 & 14 as read on A/T controller. Indicates lock-up solenoids or shift solenoids or PGM-F1 or FAS wire problem. All T/S checks are in tollerance on voltage and resistance........ I do not see how you can get this many indicated problems at-once. There must be a common thread that excapes me.
Please Help with any clues. The last step is to replace the A/T Controller... ANYONE HAVE ONE IN GOOD WORKING CONDITION for sale, or know of a repair facility for them?

No responce! I thought only I was stumped. Any thoughts or help is requested.

 

it is your controller, very common prob.

 

Thanks for my only reply. I had come to the same opinion. I do not have the necessary test hook to test ECU and A/T while hooked up. That left the lingering worry of the ECU or the FAS wire being at fault due to being un-tested. Trying to find a way to clear them before ordering the A/T unit now. This has been a learning experience due to lack of need tools to test correctly.

Many thanks David
