LOUD WHIRRING NOISE FROM CHEVY BLAZER TRANNY

Hey, guys! I have a 1995 Chevy Blazer and a rebuilt tranny. The problem is when I start the car I hear a loud whirring noise and the car acts like it doesn't want to move..about five minutes later after it warms up it moves freely. This is alos happening on the highway now and it bogs down and drives slowly. Is it the converter or tranny oil pump. I have gad this problem for a while. thaks.

It sounds more like the pump, if the converter fails it would have a crazy lock up shifting problem. Sometimes the bearing for the torque converter will loosen and spin in the housing this to could be the issue.

Transmission leaks, clunks into gear

Well your clunking noise is most likely the u-joints the leaking pan is the tranny pan what you would have to do is get a tranny kit and change the pan gasket tranny filter and fluid or take to a shop and have a tranny service done.

Blazer will not go in reverse

Need a new tranny! Just had that happen a few months ago to my 02 silverado. I would call a chevy delaership first and see if there are any recalls on them first before take it to a mechanic! Good luck with everything I know it can be a headache but make sure you get as many quotes as possible!
