Auto Transmission Irregular High rpm Gear shifts

This is what happened. My speedometer went out and then i turned off the car turned it back on idle was fine but after i put it in drive i started to see the transmission is shifting at 3000-4000 rpms at 1st etc; It also gives me a Engine Check light after i drive my car for like 6 minutes. That's not good. I was wondering if the speedometer has anything to do with my gear shifting.i wouldn't think it would but im not sure. I'm going to fix my speedometer to see if its the problem.

SOURCE: transmission downshifts erroneously

Sounds like the computer that controls the transmission.....but don't just go buy one because there is a diagnostic route.I just worked on two of those earlier this year,and the computer can drive you crazy.92 is pre OBD 2 or OBD anything,codes are pulled from the car manually.Passenger side interior,front kick panel.Remove the kick panel,locate BLUE colored TWO WIRE connector.It isnt connected to anything.Take a paper clip or wire,bend in a U,insert into connector.Turn the ignition switch on,engine off.This throws the trans computer into self diagnostic mode.Count the number of times...on the dash...the "S" light flashes.This is the code number.Now you look up the code number on a code chart.If there are NO CODES,the "S" light just comes on for 2 seconds when you turn the ignition on,then the "S" light goes back out.Thats normal operation,no codes.If no codes,you are back to square one.Welcome to code diagnostics.Remove paper clip.IF,there are any codes,they must be identified on a code chart,as a diagnostic trouble code for say...the shift solenoids,is a definite solution to this problem.Honda trans's are problematic on solenoids,shift and line pressure.So,check for codes,diagnose any codes and repair them.If no codes,or codes have been repaired,and the same symptom still persists,then it's time to look at the computer,or PCM.The PCM is located either under the carpet on the passenger side front,near the firewall,or under one of the front seats.Remove the PCM,take to a clean bench,and dissasemble.Remove outer cover and look,don't touch,look for a capacitor that may have exploded.I had very similar problems on one....the gear selector indicator would indicate Park and Overdrive....AT THE SAME TIME,when actually in Overdrive,and the car would failsafe to 3rd gear.It was a bad PCM,but did not see an exploded capacitor inside that one.Good Luck...Hondas,gotta love em.

SOURCE: transmission will not shift out of 1st gear.

Check your transmission fluid level. If the filter has never been changed, now is a good time to replace the fluid and filter.

Please Help!!! 1999 Mercury Sable doesn't seem to accelerate past first gear..engine revs up to very high rpms.


If the speedometer stops working the odometer stops also. Sounds like it is stuck in first gear. The RPM went up because the throttle was response to pedal but transmission not response. Check transmission fluid color. Whip off dipstick on a white paper towel look for gray if see any that is metal shavings and transmission is bad.

High RPM at idle or shift gears


My 94SW had the same problem, after changing many parts with no effect, the problem went away with a new MAP sensor. And my gas mileage went back to where it should have been.

Speedometer not working, high revs & won't shift out of low gear


Your issue is a bad "speed sensor". Your speedometer is controlled by a sensor in your transmission, and when it quits working your speedometer will not work, it can cause very irregular shift patterns and slipping. Replacing your speed sensor should resolve your issues.

I hope this helps you, and I wish you luck on your repair.

My transmisson makes a weezing sound when im at low speed


You sure its the transmission? Wheezing sound is usually the catylitic converter becoming plugged. Also...at 3-5K rpm you are not idling, you are reving the engine...(in that case, trans may be slipping or flairing between shifts, unless the unit is staying in one gear and just delaying shift till you reach that rpm. actual shift point should be close to 2,000rpm) I'd check the cat first.
