Tranny Knowledge needed Pls

[Grenvilleter]

Hi all…I have a ’97 ltd 4wd. Bought used . 185k KM's. I think the seller abused the tranny via towing somehow as he had recently installed a trailer hitch before i purchased. Anyhow…the oil looked burnt so I changed it a couple of times (drain &fill) without taking off the pan.

No issues for 20K until a day or 2 ago where intermittently, the tranny will not downshift into 1st gear when stopping in traffic.
Give it some throttle and slippage happens but when I pull the selector into 1st, the tranny then goes back to 1st gear and provided I put the selector back into drive, I can apply throttle and it up-shifts normally.

So…what’s happened? Can I correct this myself without doing a complete rebuild or swap?

Auto tranny’s and I are strangers in how they operate. I’ve been reading threads on complete drain and flushing but if I’m going to remove the pan, what should I look for that could be causing the problem besides crud in the filter.
:Cry:
Thanks

Sounds like you have a sticking solenoid. They are bolted to the valve body so you have to drop the pan to change them. There are 3. From what I've read though, many people change them and it does not fix the issue. Sounds like your trans got abused from lack of maintenance.

I'd drop the pan and see what it looks like in there.
