Q:are these pre adjusted 6.2 turbo 400 trans 1984 p-20 stepvan needs lot of pedel to shift
A:When a clutch pedal feels that way, it is an indication of air in the system, and when this happens, it makes it hard to operate the clutch properly because it engages even with your foot almost all the way to the floor, at times you may not even be able to place your car/van in gear due to this problem. To prevent this, you need to bleed the clutch on your Chevy van.
Q:will not shift into high gear all the time be with the modulator. i have a 1986 chevy p-30 chassis with a th400 and a 7.4 liter motor.
A:This might be the problem. However, I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.
Q:Where is this modulator on a 84 chevy caprice with a 700r transmission
A:The modulator valve is a part of the transmission vacuum. Inside the canister of the vacuum modulator.
A:Look at the transmission on the passenger side of the car. The modulator valve is in attached to the side (passenger side in your case I think) of the transmission, right about 2/3 towards the rear of the transmission., right before the tail of the transmission bolts to the main body of the transmission. It's a round piece about 2 1/2" diameter and has a vacuum hose going into it.
A:Let me know when you find that modulator on your 700r..... GM never used a modulator valve on the 700r4, the line pressure is controled by the detent cable that hooks to either the carb or throttle body depending on application and the governor driven by the tailshaft controls your shift points....
Q:where is the automatic transmission vacum modulator at under the hood of a 1995 ford trasus
A:it should be located under your car directly under the passenger side. crawl under the passenger side and look at your transmission, you should see it there.
Q:my suburban down shifts when i let off the gas would this be my problem
A:This could possibly be the problem. However, with out the presence of your vehicle we would not be able to properly diagnose it nor provide you with a 100% answer.
Q:my truck shifts into gear kinda hard sometimes i have changed trans fluid and filter can this be a problem also
A:I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.
Q:How do you adjust it?
A:For step by step instructions I recommend that you go to your nearest Advance Auto Parts store and purchase a repair manual.
A:Turn adjusting screw out for earlier shift, in for later shift.
Q:I have fluid leaking out of a circular thing on the transmission on the passenger side of my 78 C30. What is this thing?
A:With out the presence of your vehicle we would not be able to properly diagnose it nor provide you with a 100% answer.
A:Is the fluid transmission fluid? (Transmission fluid has a distinctive odor.) Is the vehicle not shifting properly? If both answers are, "Yes", this is likely the part that is leaking and needs replaced. If I remember correctly the transmission vacuum modulator is the only round part attached to the transmission on that side other than a couple of lines a few inches above it, but without looking at it I can't say for sure.
Q:Would this modulator cause a vehicle to not shift at all??
A:This could cause the transmission not to shift at all; however, with out the presence of your vehicle we would not be able to properly diagnose it.
A:To check if the modulator may be the problem, pull the vacuum line out. If transmisson fluid runs out or if there is transmission fluid in the tip of the vacuum line, the diaphragm is ruptured and the modulator will need to be replaced. This may fix your shifting problem. However, without more information it is impossible to diagnose the problem.
Q:Where is this modulator located on my 1982 GMC K2500??
A:The Vacuum Modulator is usually located on the side of the transmission. However with out the presence of your vehicle we cannot provide you with a 100% answer.
A:Passenger side right by the tailshaft has a small hose on it, and has a half inch wrench bolt an small bracket!
