    I switched my 1991 Chevrolet Camaro Z28 305 with a 350 GM crate motor.it builds up rpms, but won't shift after 20 mph.
    Cars still has the same tpi set up. The cars ran fine for about two weeks until the retention cable snapped. I replaced it and it would only go up to 35 mph, build up rpms and rev, but never go any faster. I had the cable adjusted, I had someone reset the cable ...

    The transmission fluid keeps running hot. How do I fix that? What does it mean?
    I changed the transmission 5 months ago. The rebuilt trans was working good for a while, but now the trans fluid keeps running hot and bucks sometimes when changing gears. It is a automatic.

      First make sure your radiator and condenser fins are cleaned out. Blast it with a garden hose will help keep temps cooler.

    Has a rumble sound in the rear of the vehicle at speeds over 60mph. Is this a common problem and can you help diagnose?
    We have replaced u joints and removed and cleaned and balanced the rear drive shaft.

      First question - how many miles on the vehicle? Next question, is the noise localized - coming from one side or one wheel - or more from the center? Finally, does the noise change during any driving conditions?

      The answer to these questions plus any added detail will assist with the diagnosis.

      112,000 miles on the vehicle. The noise seems to be centered. The noise seems to be more noticeable under load or while accelerating. The engine has been changed since the start of the noise and has made no difference whatsoever.

      OK - good detail. Typically, and given your description especially the noise under load - would indicate a worn pinion gear or center support bearing in the differential. Best method to test / listen - raise and support the rear end with the wheels off the ground.

      Next - with the transmission in neutral, slowly rotate the rear wheels and listen carefully to the center differential - use a mechanics stethoscope as necessary. Sometimes, you may also place a large screwdriver between the object (rear differential housing) and your ear - to listen for any growling / scraping / abnormal sounds.

      Keep in mind the noise is prominent during acceleration / under load - and may not be discerned while in the unloaded (raised / lifted) condition.

    Transmission "bucks" very hard at steady speeds. OK when accelerating.
    No warning or check engine lights. Diagnostic check of engine shows fuel and ignition systems are good. As long as there is pressure on the gas pedal, there are no symptoms. When pulling up steep hills the transmission shifts and pulls normally. Only when "cruising" ...

      Check all possible leak pints; both the external transmission leak points; hoses, fittings, seals, O-rings - as well as the radiator coolant / transmission cooling tank built into the radiator - for automatic transmission vehicles.
