How do you change Vacuum Modulator on 350 engine?
The vacuum modulator is located on the passenger side of the transmission, just above the tranny oil pan. It has a vacuum line going to it. It actuates a valve in the tranny for upshifts.
What type of transmission for a 2001 Honda Prelude?
It came in both traditional manual transmission and sequential "SportShift", which is automatic transmission that has a shifter that allows for upshifts and downshifts.
Will a new car with auto transmission downshift quickly?
Once the computer tells the transmission to downshift the car should in theory downshift just as quickly as it upshifts.
How does the servo work in a transmission?
It can vary according to the transmission. The servo's main job is to help control the application of bands to the clutches, mostly for higher gears such as 3rd or overdrive (4th gear). It is a spring loaded assembly that applies a band based on the fluid line pressure. A faulty servo can usually cause harsh upshifts/downshifts for the higher gear ranges.
1994 ford f150 transmission won't downshift from overdrive or any other gear or go in to passing gear at any speed Only when you stop will it shift down to low upshifts just fine?
I have the same problem with my 1994 F150 except it will shift down from overdrive...let me know if you get an answer..dcfrisbie@gmail.com I have a 1994 ford F150 which was doing the same thing...ended up being the throttle position sensor...Drives like a new truck after new one was installed....
What does the S mean on the gear shift in a 1988 Acura Legend?
"S" stands for sport. In this setting, the transmission has higher thresholds for upshifts and downshifts a lot faster. There are 2 sport settings, S3, which only goes up to 3rd gear and it is useful for driving on hilly terain, and S4 which is like drive, but with higher thresholds.
What causes 95 Ford Probe 2.5 V6 GT transmission to judder at low speeds from time to time and suffer from snatchy up shift?
The juddering at low speeds and snatchy upshifts in a 1995 Ford Probe 2.5 V6 GT transmission could be caused by worn transmission mounts, a faulty torque converter, or low transmission fluid. It is recommended to have the transmission mounts checked and replaced if necessary, inspect the torque converter for any issues, and ensure the transmission fluid is at the correct level and in good condition.
Your AOD transmission shifts hard when it downshifts from overdrive to third gear?
It is possible that your TV cable is adjusted incorrectly. If the cable is adjusted too tight, it can cause a hard downshift. It would also probably cause late and hard upshifts. It's unlikely this condition would "just happen" one day, but if you've done something that could have disturbed the cable, it's a possibility.
What does a s in a circle mean on the dash board of a vauxhall omega?
It means the sport mode for the automatic gearbox is turned on. This changes the way the 'box changes gear - upshifts are at much higher revs, downshifts are quicker.
How do you check to see if a turbo 400 is shifting?
first question is , is it in a vehicle at this time? if it is , you can tell by a tachometer, or you should be able to tell if the engine speed changes by the sound. the rpm's should drop each time it upshifts, and if it downshifts, the rpm's should increase.
I have a 1999 Grand Prix GT and when stuck in traffic using the brake a lot or having to brake quickly the car begins to shift gears hard when moving again what is the problem?
Sorry to be the bearer of bad news but it is most likely the solenoids in the transmission on their way to pasture. I have been driving through traffic like you and the transmission will intermittently have harsh upshifts, sometimes up to 4 or 5 before shifting to the correct gear (down shifting never had a problem). The transmission in mine finally set a code for the 'b' solenoid stuck closed :( I don't believe it has anything to do with the braking at all, but I'm no mechanic. It was highly recommended that I use the lower gear (2nd) for the engine so the transmission does not shift (in traffic only of course) - this will extend the life of the transmission but not fix the problem. I was told that it is not worth the money to try and figure out what is wrong without a code (tons of money to troubleshoot and they may not find the problem). Until the car sets a code just drive the car nicely, feel the rpms and let off the gas a little then reapply - this will help the transmission shift smoother and extend the life of the transmission (I drove mine for almost two years with the harsh upshift before the solenoid went kaput).
