transmission slips

[lou1f]

I have a 1996 2.2 auto, the trans slips in drive have to get the rpm's up to 2000 before it starts to move but if I use L1 it takes right off already changed filter ans fluid. any ideas?

Did you also change the differential fluid? If its A140E transmission in your car you will have a separate differential case. (At least my car does) It will take the same ATF as the transmission. (even the cheapo walmart one will do) My car will accelerate well and "coast" longer when I take my foot off the gas if my differential fluid reservoir is FULL.

do you have a picture..i have a gen 4

Unless you are really lucky and it just happens to be something stuck in the valve body than I'm Sorry to say but its just a matter of time until its completely fried and doens't move at all in any gear.

Most likely; but not for certain, the reason it moves in L is because of the increased line pressure induced by using this gear selection.

The fluid was brown I'd guess and lots of material? How many miles? Why did you change it in the first place? What else has been happening these past few months?

You could pull the valve body and flush it, but I'd lay odds that when you tell me the fluid was trashed she's reached a terminal condition.

Get a quote for an overhaul or park it.

Sorry,

You're starting to concern me here. . . .

Does this beg the question, "how long was it empty?"
Hmm . . .

What was the ATF/strainer change history before this?

In L you'll get the help of an additional brake band in the transmission. This helps compensate for the slippage in the clutch pack. The band is wimpy and who knows how long it'll last.

The slippage can be from low ATF (now that's not the case), plugged strainer (that's no longer the case either), low ATF line pressure (various reasons), or simply old, worn out clutch packs. Clutch packs are like your brake pads, they eventually wear out and need replacement.

These Aisin A-series transmissions have no real filtration and are very dirty. The debris in the system acts as an abrasive and causes accelerated wear. The best way to drain/refill every 10-15K miles and periodically change the strainer.

While changing out my axle I lost some differential fluid and it was dark outside and couldnt refill it. (it wasnt empty though!) That same evening I had to drive like 40 miles to help a friend with something and noticed the "coasting" difference. Next day I refilled the differential and it drove (coasted) well like before dunno why ...but just sharing my experience...

I'll check the differential fluid next. The car has 120K miles and when I first checked the fluid and screen it was pretty clean and very little metal on magnets.

How can changing the axle cause leaking of diff fluid? If the diff drain/fill bolts are not loosened fluid can not escape, right? Is there a overflow opening on diff?
