It's been having this issue for a while, but it is getting unbearable. If you stand on it, it shifts through all gears fine. If you run 75 if acts fine.

If you run a constant speed between say 40 and 60 it feels like it drops from drive to neutral, back to drive, back to neutral, back to drive, over and over. If you don't lift off the gas pedal it bangs back into drive fairly violently.

It's been suggested to check and replace vacuum lines, which I'll be starting on tomorrow time permitting. The TPS has also been suggested as a culprit.

I figure that others have had to have had this issue on here, so maybe someone can help. In the meantime I'll be searching for the answer on here in old posts. Thanks in advance for any help or input.

 

its the sensor your shifter goes trough on the side of the tranny. had the same prob. changed it and it fixed the prob

 

Thanks for the info, I'll look into that. Do you remember what it was called or about what it cost?

 

First things first make sure your trans oil level is correct, that will make it fall out of gear

 

The TRS and neutral safety switch are one and the same part. You can't replace just one.

The TRS is your problem. As it starts to wear out the internal resistance grows. The PCM can misinterpret this as you moving the shift handle to N. Since it thinks that is what you did, it obliges by shifting the trans to N.

Replace the TRS and you should be fine.
(transmission range sensor)

 

seems like it was about 50$

 

Thanks again, I'm going to pick one up and give it a go. Think I found one for as little as $45.

Yes sir, already did that. Fluid and filter change needed done anyway so I took care of that as a starting point.

 

Jim, I'm trying not to get too excited yet, but I think that fixed it. Thanks!!

 

anytime 45$ fixes a tranny, its a good day!
