My '94 Escort lx keeps burning up the ATF. What's the cause likely to be?

Your transmission is failing. Your clutches are burnt. Your check engine light should be on by now. By now you should be experiencing rough gear shifts amongst other things.

The transmission won't shift out of 3rd and will only go up to 50 mph at around 3500 rpm.

check for a bad vacum to the modulator valve on your transmission,or a bad vacum to the modulator valve on the transmission. the modulator valve to the trans. works off of vacum from the engine,look for loose or disconnected vacum lines around the carb. or the air induction system. look for cracked vacum lines that seem to be sucking air when engine running at idle speed. in park. the modulator valve [usually] located on the drivers side,of the transmission,is the main cause of shifting failure. if the valve itself is bad, it will need replacement. thank you for choosing!

Were is the modulator valve at on the tran

Hi Friend: Your Modulator Valve is Located more towards the Right Side of Transmision there will be a Vacum Line running to it. If you Have a Late Model Vehicle you will not have the Modulator Valve,You'll have a electronic System, Activated thru your Computer,and Sensors.

1995 Saturn automatic trans. shifting hard enough to brake motor mounts. Any suggestions for fixing

you may need to change the modulator valve on transmission and also check the modulator valve to be sure it's getting the proper vacum to it. the modulator valve controls shifting in the transmission. also suggest lucas transmission treatment be added to transmission fluid, it frees up stuck valves in transmission. hope this helps!!!

Engine dies when in forward gears but is fine in rev., neuteral or park.

im taking it that this is an automatic? there is a vacum modulator on the transmission. if this canister gets a hole in the diaphram it will **** trans fluid in forward gears and will cause the car to die.
another senerio is that when your starting out you have your foot on the brake you put it in gear (forward) and the car dies? you could have any number of places that a vacum leak can contribute to this problem. brakes use, vacum modulator needs so do alot of functions on todays cars get a vacum leak and they dont have what it takes to do the job. look for cracked, worn or disconnected lines around the intake and on the vacum canisters on your fender wells.
