Changing transmission fluid

I recently ourchased vehicle, so I was changing filter in automatic transmission. I put in 4Quarts of Valvoline ATF+4 fluid, that I had in my garage. After checking, I discovered that I had used the wrong fluid. Will Valvoline ATF+4 damage the transmission. If so how many times will I have to drain the fluid and add correct fluid to correct. I have not driven vehicle since. Have let it idle about 30 minutes. Thanks Ken

The ATf+4 bottle states that it is specificaly for late model Chrysler.I used it as it was left over from when I changed the filter in my 2005 Dodge Caravan. The ATf+4 replaces ATF+3 which stated it was Dexron 3 compatable. According to the product information it is pretty similar, except the ATF+4 contains Calcium-Phosphorus and Boron that is not in DexMerc.I do plan on draining it and using the DexMerc or the Maxlife, as the vehicle has 80,000 miles.

I dropped the pan today and refilled with 4 quarts of Dex/Merc just to be on the safe side.

My trucks start missing gears. It would rev up like it was in nuetral but then it would catch and go. When the truck got hotter it shifted better. I had started losing fluid. So I put some in it seemed better. But when I drove it today about 6 miles and stopped my tranny fluid started spraying everywhere in a massive puddle. So I put more in and tried to drive home real quick but my truck wouldn't move. Would only work in nuetral and had to be pushed. Any idea what is wrong

Today I added more transmission fluid and the car still didnt move. I jacked up the rear and the wheels were spinning with it on PARK. But the driveline wasnt spining. Then I started put it into gear and it only went up to 20 MPH then decreases speed while still on jack stands. Im guessing it is the differential that is the problem. But why does it only go 20 MPH when a few days earlier I tested it while on jack stands and it worked fine. Any suggestions?

I had just bought a new used trans. And while it was on jack stands it shifted fine. But once I put it on the ground it didnt move. So I put it on jack stands again and it only goes up to 20 MPH and the wheels dont spin on its own when in drive. Could it be that I have to reset the computer? Bad codes? Or bad solenoids?

I have a 96 S-10 pickup that has been handed down to me and has 101,000 miles.

The truck currently has a long upshift and a slip in 4th gear. I'm prepped to drop the pan, replace the filter, and put in some new fluid, but I'm concerned that a less-than-stellar maintenance record could cause me more tranny problems.

What I do know about previous maintenance is that the fluid was "evacuated" (sucked out through the fluid reservoir with no pan removal and no fliter replacement) at 47,000 miles. The fluid is pretty dark and I'd assume it's got that oh-so-lovely burnt smell.

Assuming worst case scenario of a transmission filter with 101,000 miles and fluid with 54,000 miles, am I just asking for problems by dropping the pan and replacing the filter and fluid?

I'll gladly perform the proper operation you recommend to get the maximum life out of the existing tranny.

Thanks!

So it's safe to say that the muck within the fluid is not holding things together? I've read the friction from the "muck" is what allows it to shift now. And replacing with new less-viscous fluid could only exacerbate the problem.

Thanks again,

'96 S10, 4x2, auto trans w/overdrive, 126,000 miles.

Have problem with trans not staying in, or not going into O.D. Added trans fluid 3 weeks ago, fixed it after a few miles. Happened again 2 days ago, added fluid, still wouldn't go into O.D, and won't today.

Truck also has 235, r75 x 15 tires which rub on turning far left or right. I think they're too big. ?

Is your check enging light on. If so go get the codes read then tell us what the codes are

The codes said 1 solenoid out, cat. Converter out or soon out.
