    Did the transmission shift normally before the filter and fluid change? Was the old seal for the transmission fluid filter removed from the transmission case without damaging the transmission case around the filter seal? The transmission fluid filter seal must be replaced if it becomes hard or brittle from heat and it must seal the filter and transmission case completely for the front pump and transmission to function properly. If the transmission has the flat thin filter with the three small screws and the flat gasket then be certain that the gasket is installed correctly or is not mis-aligned, and that the three screws securing the filter are tight. Also, check the shift solenoid filter and the filter for the pressure control solenoid, and check the transmission control fuse, and the wiring to one of the control solenoids under the transmission oil pan could be damaged or dis-connected.

The forward sprag in the transmission is broken time for a rebuild or new. a sprag is a $40.00 part but you have to use a rebuild pack with gasket so you should rebuild anyways.

When going up hills I lose momentum I changed the plugs,wires, and 02 sensor and it goes up to 3 rpms why isn't it fixed?


First check for any codes, then test vacuum with a good vac guage. When reving engine the vacuum should drop and then climb back up. Check for vacume leaks by spraying carb cleaner at any vacume hoses and intake areas but not at air filter.

then also check compression as well as look at spark plugs to see that they are all tan and no differences in any one. Go to YouTube and search for how to test engine with a vacuum gauge.

Most any problem with an engine can be diagnosed with a vacuums gauge but do use a second test method as you have learned replacing parts hoping to fix a problem is costly.

Locate transmission filter on 2002 ford escape


The '02 Ford Escape doesn't have a transmission (automatic or manual transaxle) fluid filter or even a fluid pan to house one. The transmission is mounted between the drive axle and intermediate axle, directly below the yellow transmission fluid dipstick. No need to mess with it. Change your trans. fluid at the regular specified mileage. If the fluid on the dipstick is clear, it's good. If reddish or rusty or dark, change asap.

Changed transmission fluid and filter on 2001 mustang now it will not move while it is in Drive


Well..., then just sit in the driver's seat and make noises like as if you're really driving it (ha,ha)sorry,just needed to put a smile on your face. Anyways,when/IF transmission converter is emptied,it needs to refill fully as it makes mechanisms(valves,so on)work to make the car move;now that is IF it was drained from also there. If you drained the fluid from the transmission pan(drain plug),changed the filter PROPERLY INSTALLED,refilled 2 thirds while engine off then running safely in PARK (parking brake on)fill to recommended amount checking with dipstick ,while in the car with brake pedal on,put in drive-neutral-reverse to make transmission's mechanisms make operation until car starts making a movement, then it should be okay. Are you sure you didn't nock something out of place,like linkage for gear changes??. Does the car make any noises when shifting gears??make a clunk noise??does it try to move??;need to know more details for someone to understand and find problem.

Powerglide transmission


Ouch...sat too long and the transmission fluid is probably like molasses... Try pulling the tranny pan, dump the fluid, clean the pan and change the filter and refill with DEXRON fluid. Also add some SeaFoam transmission additive. Start it up and when engine is at operating tempuature, SLOWLY put it in all gears. Shift back and forth, back and forth (with your foot on the brake !). Hopefully the new fluid and the SeaFoam will clean up the internal parts. If and whne the car is driveable, drive about 100 miles and then dump the fluid, filter and refill. Add another can of SeaFoam. Hope this helps....
Good Luck

Stumble driveing in high gear


First, check your transmission fluid. If it is low, you should fill it immediately. If it is full, but brown in color, it should be changed. A likely cause of the problem is a clogged filter. If you have not had the trans. filter changed on 60,000 or more miles, do so. It is a good idea to have the fluid flushed and refilled at this point as well. You may want to consider refilling with a synthetic fluid. This will tend to increase transmission lifespan. Just make sure the fluid is compatible with your vehicle. Mercon V is a good bet for this. Finally, there is a product called Lucas Transmission Fix. I use this in everything. I recommend using a bottle when refilling the transmission, no matter what kind of fluid you use. Put the Lucas in after 2-3 qts of transmission fluid, so as not to clog the pump at startup.

you are probably low on transmission fluid.
top it off by the dipstick while running in park. and you should be fine if it reads full, then your fluid needs to be changed or your filter is clogged. replace as necessary.if the problem continues after the fluid and filter have been changed then its time to have the transmission replaced or services.
good luck.
