It’s AT month for me!
Got out my 98 S-10 ZR2 that sat all winter. Have driven it about 35 miles. It has around 70k on it, owned since new, and it has run Dex VI since around the time that Dex VI came out.
For one thing, it has firmer shifts than the 47RE in my Ram. I used to think the 4L60E was pretty smooth, but it’s definitely more perceivable than the 47RE... not harsh, not firm, not clunking or slamming, just more noticeable. I’m not sure if that’s pointing towards something else...
For whatever reason I don’t get any creep along forward or backwards anymore. Sitting, idling, remove the brakes, and it won’t roll forward in D, or backwards in R. Once a tiny bit of throttle is applied it will roll along, and it drives and shifts fine (note I feel like the shifts are slightly more noticeable). No clunks, no noises, just thst tiny bit of throttle is all it takes to get it to creep along, albeit slowly.
The other thing I noticed is thst when driving along slow, like in a parking lot, if you coast down for a few seconds, and then hit the throttle, it can sort of clunk, like it catches harder a split second after giving throttle. But it runs fine any other condition. Not sure what that means though in terms of operations.
I have no reason to believe there is anything intrinsically wrong with the AT, it is fairly low mileage, has seen a relatively easy life, and this seems to have been induced by sitting... but putting 35 miles of varied use hasnt helped (yet).
Haven’t dug in much yet, but curious if there are any obvious things that I should be looking for?
The only other issue I’ve had in recent years is the front axle actuator (vacuum), causing a slight grind if the vac reservoir got too low. Not happening currently, driving in 2wd on streets, all seems ok. Truck starts and runs beautifully, catching on the first cylinder, first crank afte sitting for months.
Havent checked fluid level full hot yet, but seems OK...
No indication of seized caliper or parking brake.
What could be the issue?
