ok if i could get some help cause im going crazy with this its been a year of trying to figure this out. i have a 99 s10 blazer 4wd, last year it started to squeel, i put a gator back belt on, i put a new water pump on, i put a new belt tensioner pulley on, i put a new dumby pulley on, i put a new alternator on, i put a new clutch fan on and nothing has worked. it doest start until the truck heats up at like running temp, its never over heated i had the tranny rebuilt under warranty but they reused the old torque converter. well after dumping all of my money into this squeel and its still here. i took the belt off and it still squeels so now i found out that everything i replaced on the front was about use less. the sound seems like its coming from the back of the motor or the front of the tranny you can hear it really good underneath the car. i no longer have a warranty on the tranny. i just didnt know if a torque convert could squeel because that was not replaced or if its something else i just dont want to pay someone to put a new torque convertor in and it not fix the problem and spend alot of money for nothing. can someone plz help me. im open to everyones ideas plz.
