Question about 1982 Ford F 150

1 Answer

1982 F100 vacuum modulator, C5 trans

I have to rev the engine to get it to go in drive. Reverse has no problem. Fluids are normal. Replaced vacuum modulator twice. And the new modulators don't have a pin in the back like the old one did.

Revs in reverse

While driving 91 olds cutlass supreme engine revs high but speed does not match, transmission fluid levels are normal


It's possible that the transmission modulator hose came off the valve or has a hole in it. Check the pass side of the trans for a hose hanging or other problems. If not there, check where it hooks to a vacuum source at the engine.

there is a vacuum modulator on the back (pass side ) of the trans.it will have a small port in the center,(facing rear of car) hook up manifold vacuum to it and it should work.

Trans does not want to respond in reverse & o/d light is flashing


With high mileage automatic transmissions, that have not been regularly replacing the transmission oil, it can cause major problems if you do change the oil. The sealing integrity in the valve block can be lost by flushing with new oil,
Firstly, just check and make sure the oil level is correct. Do this by running the engine, with your foot on the brake, go through all the shift positions 2-3 times, holding in those positions for a few seconds each time. Then put into park , still with the engine running, and check the oil level . if its a little low, add a small amount at a time till you get the correct level, each time going through the shift positions and then checking.

No reverse after rebuild on 4L60E Transmission from 1995 GMC Sono


There isn't a modulator on this trans as it is electronic

You can have first gear going forwrd but no reverse. It is possible. The low/ reverse clutch isn't needed to go forward.

Engine Rev Trans does not grab going Forward


We had the very same problem and I found this post somewhere on the net and it worked! After ours stopped going forward, it went in reverse fine too then it stopped moving completely. We just pulled the sensor off today and are looking for a new one but at least the car goes great now. 15th Jul 2007, 21:04 Bought my wife a 99 Ford Taurus at auction. Like others the Transmission sensor gave out. A temporary quick fix is to open the hood, and simply pull off the sensor connector plug on top of the transmission. The transmission will now operate properly in both OD and drive. You will notice your rpm's are steady as your speed goes up - loss of fuel economy due to the failed sensor ( to technical to explain here...). Two things to do: Change out the old transmission fluid immediately - its gonna require synthetic fluid at a higher price, but is worth it as it shifts far better now. And change out the coolant. In fact, I suggest changing out ALL of the fluids and start clean. Until you get the sensor replaced your fuel economy will **** for a while, but its better than not having wheels at all and it IS safe to drive.

1993 Mustang 2.3 AOD Auto Trans, after storing over winter took on 200 mile trip did find, next time after warmed up and turned off then back on trans slips in upper forward gears. ????? When cold fine, or...


I don't recall ever seeing an AOD trans behind a 2.3 ltr 4 cylinder engine,all the one's i've seen had the A4LD trans in it.That model trans utilizes a vacuum modulator that is mounted on the passenger side of the trans case.The vacuum modulator is responsible in large part for the trans upshifting at the proper speeds.I have seen plenty of cases where those modulators go bad.When this happens,late shifting is experienced,and the same thing happens if any of the vacuum lines under the hood have a problem,like cracks,small vacuum leaks,etc.To diagnose,you have to get under the car,and disconnect the vacuum line from the modulator.If the modulator is bad,trans fluid will run out.If the modulator is good,no fluid will run out.Hook a vacuum gauge to the line down at the trans,and start the engine.Idle vacuum should be 15-18 psi,and when the throttle is abruptly applied to wide open throttle,vacuum should drop to near zero.There is one other area to look for problems on this trans,still externally,and that is the servos.They are located also on the passenger side of the trans case,and there are 2 of them.They are round circular aluminum covers held in place in round bores with snap rings.They can be removed,and are black metal stampings coated in rubber.If the rubber lip seals are hardened up from the exhaust heat,replace them,and you may get your gears back.Good luck.
