Having problems with your 1992 Buick Roadmaster ?
Does the 1992 buick roadmaster have a vacuum modulator to shift the transmission gears?
\015 I'm talking about my sons car and he said it is shifting later or at a higher speed. I've replaced these and or the vacuum hoses before on other models. I suppose low on fluid condition could cause this also. I hope he has already checked this. He lives out of state and I can only advise him. Thank you for any idea you can share. He loves this car that will very soon be turning 300,000 miles.\015

The vacuum modulator line on my 1988 Chevy Suburban Diesel has come off at the engine end. I have followed it to the passenger side of the transmission. It is connected there. Where is the other end supposed to go? My transmission is not shifting into gear. Could having the vacuum hose off be causing this problem?

I was stopped at a traffic light. When I went to step on the gas my transmission slipped out of gear. I tried to shift it into all of the other gears but it still would not move. I tried to use the four wheel drive both high and low but still no response. I then purchased some dextron III and added it to the fluid but no response. There is not any fluid on the ground either. the fluid looked very clean when I checked it. Would a vacuum or computer module cause this problem? Does it have either?
Hmmmm. You may want to have the OBD codes checked to see if you have a bad shift solenoid.\015\012\015\012The other bad news is....if the car doesnt use electronically controlled shift solenoids your probably just have worn out friction ... Mazda Navajo
I have a c4 ford transmission that had got rebuilt i reinstalled it back into my truck and drove it up and down the road, it seemed to not shift properly but it did shift so i parked it at my shop to check for proper vacuum at the module and it was good then went to move the truck again and now i have no forward gears but i have reverse i'm just wondering if any body knows if it could be something in the valve body or what be could be wrong the oil looks and smells ok

Transmission shifts into 1st gear as it should but when its time to shift into 2nd gear I have to push the RPM up to 4 (Speed up to 30) then lay off the gas & then it will shift into the 2nd gear & so on. All vacuums are secured on. No liquids leaking. Transmission fluid & filter has been changed 1 day ago. The transmission is not slipping or jerking it just takes a longer time to change, is there a sensor that controls the valves to open up.
Possiblity there could be a sensor, or you could have a valve sticking or going bad inside the transmission. good luck ... 2002 Chevrolet Tahoe

My 1994 BUICK ROADMASTER shutters or hitches between 50 and 65 when it shifts into 4th gear. (overdrive) i replaced the transmission filter and prior to that i ran some sea foam thru it to clean it a bit. it seems to improved slightly but its still there. i can make it drive smoothly by letting my foot off the gas slightly and giving it more every few seconds between these speeds. i dont know if it downshifts when i do this or what but its really irritating. any help is appreciated. oh ueah it h

1994 Buick Skylark, 138,000 mi.,V-6, auto trans. Car won't engage in gear until engine is warm. Engine must run 4-8 minutes until shifting successfully. Shift lever can be moved to all gears, but transmission doesn't actually engage until engine is warm. Once transmission engages there are no problems driving. If I shut engine off, then restart, transmission will engage as long as engine has not cooled down. I checked fluid level with engine idling and warm and levels were okay. Problem h

I have a 1994 roadmaster, got the trans rebuilt and still won't shift properly. Hard shifts from whatever gear it takes off in to the next gear when first started, afterwards shifts easier, however it never gets into first gear and starts off in 2nd or 3rd gear. Trans man said he's check 4 times and pulls a code 84 from the computer. He says the computer needs to be reflashed, buick dealer says the code (84) is a 2-3 shift solenoid circuit fault. At any rate it doesn't work well and is eating lo

My 2000 Buick LeSabre whines and will not shift into any forward gears. It also has a very loud whining noise. Car starts fine and I am able to put the car in to reverse.

3.8L Ford Windstar with automatic transmission. When first started, the transmission will go into gear, forward or reverse, and I can drive for a time. Then the transmission slips out of gear and I have to shut off the engine, wait a few minutes, restart, and again I can drive the vehicle for a time. Is this just a simple clogged filter? Planning on replacing the filter and fluid tomorrow as a first step. What is a vacuum modulator, where is it located, can it be cleaned or replaced, and

I have a 93 Nissan Altima (AT transmission) and while driving my car....sometimes the speed ometer stays on "0" and the RPM goes up while I have my foot on the gas and it sounds like it is stuck in first gear. Then after a minute or so it will shift over and the speed ometer will go to normal and you can hear the gear switch over & the car will also **** a little while it goes into the next gear. Does this sound like it needs a new transmission?
Speedometer failed when the cable is broken; if the gears wont egnage, its possible that you have any propblem in the Torque Converter or Solenoids. First try with mainenance and check fluids. ... 1993 Nissan Altima
1991 Chev 1500 pickup, 5L, 4 speed o/d automatic transmission shifts roughly, especially at lower gears. Is there still a modulator valve? If not what controls shift timing?
