    acceleration stumbles unless throttle is feathered

    Where can I buy coolant lines for a 4L80e?

    One of the transmission coolant lines on my 91 Suburban is leaking. It's the 4L80e. Does anyone have a source for buying replacement lines? I think the original is bent and therefore can't make a proper seal anymore. I've looked online and can't seem to find any. Thanks.

    Computer question

    I have a 1991 4WD 3/4 ton Suburban 5.7 350 4L80 transmission. Some time in the past a body from a 1990 2WD 2500 was put on the chassis. So, I guess you could call it a hybrid. My question is, would problems occur if the computer is from the 2WD? If yes, should I look for a computer from...

    Hey Everyone, I have a 91 V2500 with a 5.7 350 TBI motor (4x4 with 4L80E transmission & NP241C transfer case). The problem I'm having is that when the Suburban warms up it starts hesitating when at cruising speed (just about any speed above 40 mph). It acts like its losing power &...
