Question about 1999 Ford Taurus

1 Answer

Maybe a transmission problem?

Hello, When I am driving at faster speeds, 50 and over, my car does not shift into a higher gear. The RPMs just go up. The same thing happened to me on a turnpike last week. I was leaving a rest area and accelerating, (in D, not OD) when the car hit about 50 mph, it suddenly "over-revved" and the RPM on the gauge shot up to around 5200 RPM. I had to slow down to around 25 mph, then slowly speed up again... took 3 or 4 tried before I could finally get back up to highway speed and rpm was normal. It DID feel like I was in Neutral while was experiencing the issue.

    Have you checked the transmission oil? If it isn't the transmission it could be a failing torque converter.

    Get the MAP sensor checked.

If you're only in "D", you should switch to "OD" when driving at higher speeds. "D" only allows you to move up to third gear whereas "OD" will move you into fourth. You're over-working your transmission by driving in "D".

Transmission making loud grinding/sucking sound, doesn't go when in drive or reverse

Is it an automatic John? When was the last time you checked the level of your ATF (automatic transmission fluid)?

There are many different types, so make sure you get the right one.

If it is a manual shift, check the gearbox oil level. If that is OK, you need a transmission specialist. Look in Yellow Pages.

I have a 2005 Suzuki Verona EX. When shifting into gear, the car slams itself into gear hard. Then when driving, it acts like it is starting off in second or third gear. I can have the pedal to the floor...

run the fault codes to determine the fault are a first
next check the vacuum hose for the transmission actuator as that unit has a lot to do with shifting ratios

91 honda accord between 50 and 55 it feels like the transmission shifts up and down conststantly but the rpm only moves from 2100 rpm to 2000 rpm but over or under that speed it runs fine.

Your transmission is probably jumping in and out of "torque converter lockup". The lockup is the most efficient mode because 100% of the power from the engine goes to the wheels and is not lost in the torque converter. It only goes into lockup at higher speeds, but will jump out if the computer senses it needs more power (at the higher engine RPMs) to maintain or increase your speed. I recommend either going faster or slower if this is bothering you. :-)

Two problems with '97 Pontiac Bonneville 1: automatic transmission does not shift into higher gear at correct time as it once did, resulting in engine running in higher rpms before gear shift occurs. 2:...

You may have low vacuum pressure which can screw up the fuel regulator as well as shift points. I would start by checking for vacuum at idle, and if low, check for a disconnected, broken or kinked hose.

With normal acceleration the 1st to second shift point should be around 2500-3000 rpm. Most of your shifts under moderate acceleration will take place at this same point or when there a light load on the transmission. Under hard acceleration the RPMs will climp higher due to increased power needs and the computer will shift when less power is needed or the RPMs climb to an unsafe speed say5000-6000rpms (depending on where yours redlines). Also going up a steep hill will raise the RPMs higher and goind down a hill will cause a faster shift at lower RPMs. These can always be altered by an individual owner by adjusting shift points, using performance parts and if you have problems (low tranny fluid/trans issues). Your trans RPMS are fine and will vary depening on how your foot accelerates. The shift pattern should be the same every time you drive slow/medium/fast/, look for changes in those patterns you will also catch a problem early.

My jeep will drive normally until i feel the automatic transmission switch into second gear. Once the gear changes, the rpms rev up but there is no power going towards the wheels

maybe the speed sensor on the transmission monitors transmission speed and sends info to computer to control shifting not sure if this is helpful
