If the blazer is wheezing, it could be transmission, but if it has 4-wheel drive, check to make sure that the gear is correctly shifted.
depends is it standard or automatic
If the transmission is slipping or shifting badly it COULD be a sign of a valve body failure. If the transmission will not engage reverse or any of the forward gears, it COULD be a sign of a valve body failure.
There can be a number of problems that indicate that a transmission is failing; 1. slipping 2. failure to go into gear 3. leaking 4. noises 5. failure to shift at the right speed
You might need to change the fuel filter. Or you might need to replace the fuel pump.
There are numerous signs of transmission problems. You may have trouble getting the car into gear or it may smell like it's burning. With either of these, you should first check the transmission fluid level while the car is warm and at an idle.
Inadequate fuel pressure. If that 2000 S10 Blazer has a 4.3 engine, it needs 61 to 66 psi (engine off with fuel pump running) to run properly.
The first thing I look at is the trans fluid. It should be bright red; if it is dark and SMELLS burnt that is a sign of problems. Does the trans slip? If you have not done so, change the filter and flush the fluid many times that can work wonders. Good luck.
They get noisy, squeal and vibrate. Also if you keep burning out the blower motor resistor, that is a sign the blower motor is on its way out.
There are many signs of heart failure and everyone will experience different signs. Shortness of breathe and tingling on the left arm are primary signs of a heart attack.
If the transmission is slipping (the engine revs up when it shifts), if the transmission shifts late, even under normal acceleration, or if the tansmission simply won't shift, you should get it checked. Also make sure the fluid level is adequate.
That is one of the signs that your transmission is going bad. Better have it checked at your local mechanic before it leaves you stranded.
The usual symptom of failure of the left ventricle is death.
