Default 4EAT Sloppiness......AT guru's please chime in !

Pretty vague thread title huh..

Mods..16G and all supporting.
Big tranny cooler and regularly changed Amsoil ATF

I've noticed over the past several months some (what I can only consider as) sloppiness. No slippage under acceleration or anything.

There are some clunks when shifting from park to REV, some "wobbly sloppiness" when lifting off throttle while cruising in traffic...that sort of stuff.

The trans shifts fine through all the gears, it just doesn't feel very "tight" which I can probably attribute to the higher than stock HP and TQ.

I don't beat on it, but its right around 104K and am wondering if there are any remedies.

Center diff?
Driveshaft U-joints?
Entire driveshaft?
Muffler bearings?
Tightening (or maybe loosening) the nut behind the wheel?

Any ideas on this one?

Honestly I just think the transmission is normally wearing. As more debris gets into the valve body and passages, and the clutch packs wear down, as with any auto, they start becoming more sloppy.

Do you have any whining noises? I would say the center diff is a good place to start looking. Unless your transmission mount has failed.

It sounds like a loose or cracking mount to me. Check motor mounts while you're down there.

Thats a good place to start. I replaced the trans mount bushing a while back with the Rallitek (I think) harder model.

No, I don't have any whining sounds.

When I shift from Park to Drive or Park to REV, there is usually an audible "Clunk". But again, its just a sound that happens once. Most likely a solenoid or something?

Can the driveshaft wear out?

The reason I ask is because, years ago I had a toyota pickup converted into a camper. It had an AT and was really sloppy feeling. One day, one of the U-joints finally gave out and I had the whole DS replaced. It felt like a new truck when I got it back.

Hows that for a completely random and unrelatable comparison!

Well if your driveshaft is indeed fubar, you would know! I'm assuming its mount related. If a solenoid in the valve body failed, you would have rough shifts etc. It's more than likely an external issue than internal.

Maybe one day a built trans, but if I'm going to drop that kind of money, I'd end up going with a 6 speed.

OK

So your suggestions are trans mounts and motor mounts?

I'm not even 100% sure how to check the motor mounts? I know they are stock and the only time they have been remothely messed with would have been during UP replacements.

The best thing to do is jack up the car and see if there is movement on the mounts themselves. Or just see if you are able to identify visible cracks or so on the mounts themselves. I'm assuming these are stock and not aftermarket.

If its anything else it would be internal to be honest.

Still haven't had tome to get under the car

I'll plan to start with checking the mounts, and move on from there.
