Nothing can be done other than what your already doing. 3-4 clutches are gone. thats something i seen everyday for 7 years working in a trans shop. only other option besides buying one is a rebuild. sorry.

Are you sure its slipping and not going into a lower gear? the passing gear linkage may be too tight..check that too

I assume that we are talking about an auto tranny here. If you have manual transmission, then you likely have to replace the gear box.

If you have automatic transmission:

If it doesn't switch to the upper gears at all, then a possibility is that one or more gear shift solenoid switches located in the valve body are probably defective. The solenoid pack is an array of switches located inside the transmission, behind the valve body cover. When one solenoid in the pack is defective, the transmission will never switch to that determined gear.
Each solenoid can be tested by reading impedance at its contacts with an Ohm meter. If the solenoid is defective it will read Open (Ohms infinity).

Other common problem that may result in the symptoms described is a faulty TPS. The TPS is the throttle position sensor. This is located in the throttle body, under the hood. When the TPS is defective, the TCM, which is the electronic control module managing transmission, get an incorrect input, and the result is no shifting or shifting at the wrong time. The TPS is tested reading impedance or volts at its contacts while slowly pressing the accelerator pedal. If there are gaps in volts reading, or if voltage does not decrease/increase smoothly, then the TPS is bad.

If the above are OK, check the knock sensor. That is also used by the TCM to decide when to shift.

If all the rest is OK you have either a bad TCM or a problem with the gear box.

SOURCE: transmission slipping on 03 GMC Envoy. what does iy mean when trans fluid measure high on dip stick?

Two things: #1 someone has overfilled it by mistake thinking they were putting oil in the engine. Yes I have seen this.
#2 The transmission cooler in the radiator could be leaking antifreeze into the transmission through the cooling line raising the fluid level. I would look for milk shake foam on the dip stick and make sure you check trans in park and not neutral.

98 crown vic transmission slipping

Change the filter and fluid. This car if the transmission is original should have a torque converter drain. Drain the torque converter also,it gets almost all the fluid out of the transmission. Doing this the car will require almost 12 quarts of fluid. Worth a shot. I change mine at 25000 mile intervals.

Take no chances and change the fluid and filter on the van. If that does not correct the problem then you will need to take it to a transmission shop for repairs. Hope this will help you.

Transmission will stay in 2nd gear


When was the last time you service the tranny?

Fluid should be topped to level, pinkish in color and no burnt smell.

This happened two months ago; my cousin's Intrigue was slipping on 2nd n 3rd when it reached 2000 rpms. and some times when trying to take off suddenly, Have to released the gas a little and you could feel it engaging again.

Solution: Changed Transmission fluid and filter and added one bottle of RISLONE Transmission Stop Slip and Leak Repair I got at AutoZone ($10), It stopped the slipping after driving the car a couple of miles, you can actually feel more traccion in all gears and my cousin says is even giving more miles X gallon. He drives the car about 80 miles a day and is been over two months since. It may sound like a commercial ad but that stuff works great!!!

Rate this answer and keep me posted!! Good Luck!!

The car is getting any power when put into drive, it takes long to get power to move faster, i can also hear a loud noise when its in drive but when its in park the noise dissappears!

Could be the catalitic converter. Have someone push down on the gas petal while you feel the exhaust coming out of pipe.The farther the petal is pushed, the more exhaust you should feel coming out
I had to replace mine in my 2001 at 44000 miles. I got a high flow type converter.

Auto transmition wont go into 3rd and 4th gear

I had the same problem I changed the transmission fluid & put a new filter in the trans, this fixed it good until I put my foot down to overtake the trans kicked down to 2nd gear & the hold light started flashing again & the trans started slipping again. I stressed over it for a day or 2 & then I took it out for a drive & thrashed it, Low & behold it came right. When you change fluid its impossible to get all the old fluid out because the torque converter holds a liter or two under pressure, so when I put my foot down some of the gunk blew through & blocked the pump it looses pressure & cant change gear. You need to get it flushed by a transmission specialist

If you havent already try to change the transmission filter.Sometimes when the filter gets dirty fluid pressure is comprimised and certain pumps and solenoids which control shifting inside the transmission function off of the fluid pressure,
