I bought a 3200 single disk from Circle_D for my 4l60 a few months ago since ive installed it ive put about 2500 miles on it. its been running great till the other day. i was pulling about a 3000 pound load and it pulled fine. i got on it a few times and it passed with ease. when we were out and about i had to go pick up one of the quads and my trucks 2wd at the moment and we were in the washes so from time to time i would have to mash it not to get stuck. once i got back to hook up the rig, i noticed my truck wasnt acting right. i pulled home and it shifted threw the gears " about 40 miles" once i got everything unloaded i messed around a bit. the truck would only stall up to 1800. and also if i was at a dead stop-30 mph i could floor it it would act all boggy then around 30 it would just take off like a bat outa hell. if im cruising and give it the 1/4 throttle or even half throttle it acts like a dog i gotta give it 3/4 or full but when i do it drives normal? the tranny is a stock 4l60e with vette servos and a 40k trans cooler. my truck has a built 5.3 pushing around 350 hp so im thinking its the tranny since it has about 150,000 on it. a few buddies were saying that it could be one of the bands preventing it from building up down low? i was just wondering what you guys though and also how safe it is to drive? i plan on getting a built tranny with my income taxes just have to wait another month thanks for the help
