    Sounds as if torque converter is locking an unlocking. Very common issue and can be caused by bad solenoid, control circuit or bad converter.

the fourth clutch is burnt probably due to a bad 4th clutch piston seal... if you can get a good trans that cheap then you should just put one in it unless you are familiar with internal trans repairs...

SOURCE: There is a loud noise at 45mph.

Find a quiet empty stretch of road. Go 50 mph, put the trans in NEUTRAL and shut the engine. If noise is still there, swing car left and right to detect noise differences. Could be hub or axle bearings. Not engine or trans if noise is still there. Hope this helps

1998 GMC Jimmy will only go 30 mph and the rpms are reving high what is wrong


If you have an automatic trans, sounds like it is slipping, Try changing the trans filter and fluid, but your trans may have to be rebuilt. Only other thing could be brakes dragging/stuck.

Since the transmission shifting and torque converter lock (cruise speeds) up are computer controlled you need to have a scanner hooked up that can read Transmission control module (TCM) fault codes. Also check for engine codes as this could be a misfire, but in that case the check engine light should be flashing while the engine is misfiring and set a fault code. If no codes of any kind are present in memory when the testing is done you almost certainly have a mechanical fault in the transmission like a malfunctioning torque converter clutch, but even that should set a fault code, so have the testing done.

2002 regal would slow down going up hills then


the catalytic converter most likely is no the sorurce of the problem, older design bead type Cat converters used to plug, but it is very rare on the newer ceramic honeycomb cats, u need to have the electronic engine control tested, are u getting a check engije light? if not has the fuel filter been replaced every 30,000 miles? also a part called the Mass Airflow sensor can cause these symptoms as well as igntion system problems.

When I accelerate it does a fluctuation in gears...the rpm goes up and down...even when im driving at 40 mph it shifts then it hesitates at that speed..could it be the throttle sensor is dirty?


Is the "check engine" light on??? to isolate your problem have you tried MANUALLY shifting the trans (automatic) and still doing it?? check the fluid level and condition of the oil...sound more like the trans is slipping...the "TP" sensor will effect the engine and trans.But not cause over-reving......hope this helps...GL

ABS brakes shudder


YOU NEED A SCANNER TO MONITOR THE WHEEL SPEED SENSORS. THE ABS IS SENSING A SKID AND THE ABS IS ACTIVATED WHEN THIS HAPPENS. THERE MAY BE A CODE FOR THE HUB THAT IS CAUSING THE ABS TO ACTIVATE.

CHECK THE WIRES FROM THE SENSORS FOR BREAKS OR CHAFFING. AN OHM READING OF THE SENSOR SHOULD BE 850-1200 OHMS, AND AND A-C VOLTAGE READING SHOULD BE 100 MV WITH YOU TURNING THE WHEEL BY HAND.

RATE ME, PLEASE

Oil relatied engine problem...maybe? need help


The clicking sound is from lack of oil or lack of oil pressure. When the lifters pump out then they have too much slack in them and thus the clicking or tapping sound. Sorry to say this, but the engine is either very tired or the oil pump has about had it.

Engine overspeeds while the trans is in the drive position


Good idea, hopefully the source of the leak, and new filter & fluid will put you back on the road in running order. The slippage was caused by the leak, causing low fluid level. Keep fingers crossed that you shut it down soon enough that it didn't cause extensive damage internally in transmission. Don't forget, when you get diagnosis & repair estimate, if it sounds too high, you have the option of a second opinion, so feel free to get back to us, or consult with another repair shop, or transmission repair place for advice on estimate, before you commit. Good Luck, and keep us posted.
