If it's a sensor usually the AT or POWER light will blink 16 times at start up.
No flashing but it's been a while so I need to check.
1. does the light blink at start up?
I don't think so but I will have to check again
2. what is the fluid level sitting at? At the proper level,
I had changed it out a few months before it stopped and was at the right level last time I checked
3. is the fluid nice, new, bright pink or something else?
I was surprised the first time I swapped it out. It had not been changed and was still nice and red when I first changed it
4. if you move the shifter lever in the cabin - does the corresponding cabling on the passengers side of the transmission move properly too?
Hmm, good question, I'll have to check
5. does the inhibitor switch seem to be switching properly? Another item I'll have to look at 6. are there any check engine lights?
I believe there was a check engine light. I need to it on and start it up to see what is on or flashing.
7. is the transmission pan dented? I actually know this answer, no. 8. any prior trans work or accidents?
No
9. if you leave it in drive and rev the RPM's a small amount and leave it in drive for 1 minutes - does it eventually go into gear?
It used to, This all started about a year ago with a little hesitation and kept getting worse. I replaced the fluid 3 time over about 3 months using high mileage trans fluid and sea foam. It worked great for a while then came back. I replaced the fluid again and didn't help as much as the first series. Eventually, everything stopped. Reverse worked fine up to the final outage. It never smelled hot.
I did have to replace the HG's and the AT light came on when the engine overheated. That happened about 3 times. The radiator and water pump have been replaced just prior to having the HG's replaced.
10. if you turn the car on and off a few time and keep moving the selector - will it go into gear?
Not repeatedly. I was afraid of making things worse. I'll give it a shot.
11. when you move the selector by hand - does hte corresponding selector range on the instrument cluster change?
This model/year doesn't have it on the dash, always frustrated me to have to look down at the console.
The Trans-X sounds pretty potent, Towards the end I tried some other stuff which was pretty thick. Now I'm thinking it may have aggrevated the situation.
Thanks everyone!
