i have loss of power? 2000 Chevy S-10 4 Cylinder


Last 2-3 days

High pitch whining noise (sometimes) when accelerating.

Tractor/lawnmower engine-like sound only when accelerating.

Loss of power when pressing down on gas pedal too hard (low rumbling sound).

rpms winding a bit high before changing gears.

A/C is working fine, truck is cranking fine, and check engine light hasn’t come on??



Last Few months

On interstate, very hard shaking at 55mph + over and motor is winding out but doesn’t seem to be changing into overdrive or highest gear. I usually can’t go over 60 mph. Sometimes check engine light comes on after I’ve been driving on interstate for awhile, and when I finally come to a stop, the gears seems to change very very hard. But then after a day or so the light goes off and the gears don’t seem to be changing as hard then.
 
Could be the bearings might be going bad in the alternator and that could be the squealing noise you speak of.
Check engine compartment for bad vacuum hoses with cracks and repair.
Could have a cracked exhaust manifold or bad exhaust gasket.
Check fluid level in the transmission with engine running .I think it could be low on fluid.
