I'm not sure, but it may be time to have the transmission serviced.
The transmission is not shifting in and out of gear or your front joint is going bad
Try changeing the fuel filter,I had the same problem and it helped.
NO
I would say that you are losing coolant somewhere hoses,water pump,radiator.
A lack of oil in the engine./ the sensor in the oil system./ broken oil pump
yes check you vacum line in the back of your transmison
Likely the blower motor is bad, causing increased current and blowing the fuse. Replace the blower motor.
it sounds like a steady bearing on the drive train or pssibly your tourque converter is going bad
The first two steps are check the fluid and check the computer for trouble codes.
Sounds like a torque converter issue, have it checked at a transmission shop
There are several things that can cause shifting problems in your 1989 Chevrolet Blazer transmission. The most common cause of shifting problems is a lack of transmission fluid. Broken shifting forks can also cause transmission shifting problems.
check transmission fluid for correct amount or being dirty if fluid is ok your transmission is wearing out
