My transmisson makes a weezing sound when im at low speed

Check the transmission fluid level, it sounds like it is low and when it get warm it is high enough to work.

HAVE YOU REPLACED THE IDLE SPEED CONTROL VALVE?

Low transmisson fluid, Transmission filter or faulty transmission pump, the pump usually will whine before it goes out tho, Im leaning towards the filter or low fluid. Check your transmission control selonoid.

Sounds like low ATF. Check your transmission fluid.

could be water pump

If this is for your Mighty Max truck, the problem could be the idle air control valve. The computer controls the idle speed by regulating how much air enters the throttle body thru the valve.

It sounds like transmission. When the transmission begins to be sluggish. You can push the gas and the rpm will rise, but the car will not go anywhere or gain speed. Check the transmission fluid level to make sure it is at the appropriate level. If it is low, fill to proper level. This should make it go into gear better.

I don't know how much oil you had to put in but it sounds like you have maybe more than opne issue and both sound major. One is engine reving and speed not picking up sounds like trans problem. Two the engine shaking and making noise and being run low on oil leans toward possible engine damage. If your mechanicly inclined check all fluids and when checking trans fluid smell it. If it smells burnt the trans has been damaged. Check oil pressure and make sure coolant is full.You may have to take it into the shop.

have you checked your transmission fluid, might be is low

replace water pump
