Question about 1990 Ford F150

1 Answer

1990 Ford F150 Rpm revs up two or three thousand RPM when in gear

Its an automatic transmission, when I put it in drive or reverse the RPM's jump up and down between one thousand and as high as three thousand RPM. I checked throttle caple and spring and all that and it seemed to be fully opening and closing completely. Any ideas?

Its sounds like your trans clutch plates are wearing out try thicker oil or it may be time for a serious replacement

If you check and drain your oil that's where you'll find your answers its supposed to be bright red not brown or smell like burnt so its a start to begin checking

When put into reverse and gas is pressed car goes nowhere but revs up when car is put in drive and revs to 4000 RPM it just inches forward. Any idea why?


If it's an automatic, is there fluid in the transmission? If the fluid is ok, the transmission is bad. If it's a straight stick, the clutch is bad.

I have a 1993 Ford Explorer that goes into high idle when I put in gear. It does this when the engine is hot or cold.


On some cars there's a speed sensor on the clutch or transmission. That might cause an idle problem.

I have a 1990 ranger. transmission was replaced before i got the truck. the people i got the truck from said that changing the transmission didnt fix the problem. the problem is when i put it in reverse to...


I think the problem is the torque converter or similar. Check fluid level and condition. If fluid smells burnt or is dark in color something internal is wrong. You said transmission was replaced do you have the paperwork? Either the transmission wasn't rebuilt correctly or the torque converter wasn't replaced. Read computer for codes.

I assume this is an automatic transmission. Is it a twin turbo or a non-turbo model? It sounds like you've lost fourth gear and are stuck in 3rd - those RPM would be about right. If you can provide more information, it will probably help in the diagnosis.
