    Transmission software

    Ok, old thread, but thinking about the black bear tune now because I have tried everything and successfully eliminated every vibration from driveline and just had tires balanced and is smooth as butter. My hypertech got stolen but it was ok for a canned tune, but can this black bear tune help...

    Driveshaft vibration video

    I went to my father in laws auto repair shop and took the drive shaft out. Showed how binded and tight the rear u joint was. He told me to rest the u joint on the clamp and tap the bottom of the ears and it was a smooth rotation. Put the clips back on which looked like they were wedged to one...

    Driveshaft vibration video

    I guess I'll drop the driveline again. If I have to buy a new ujoint, do I have to match the u joint on the slip yoke side? The ones I have now are Spicer with the zerk fitting.

The damn bolts that cam with the straps Are about 1/4 inch longer than what was on there before and had to really crank down on the bolts to get it tight....i need maybe to...

    Driveshaft vibration video

    I tried to tap the spot you are talking about with a small hammer, but was scared to tweek the driveshaft. I think the retaining clips are too thick on that Spicer ujoint. Can I just remove the clips and sand them down a little to relive the tight binding? I guess I should try before getting a...

    Driveshaft vibration video

    You are right! Finally pulled driveshaft yesterday and found the problem. I bought the Tahoe 1 year ago and u joints looked new but like you said someone pressed them in wrong because the rear ujoint was so tight(binding) and the slip yoke dry. So I tried to relieve some pressure on the rear...

    Transfer Case oil recommendation

    Swathdiver, thanks for the info. You've seen my video of my driveline noise....now I'm thinking it feels like it could be my rear differential clutches???? My rpo code is gu4....do I have clutches in my rear diff?

    Transfer Case oil recommendation

    Keeping Transmission pan cooler

    Keeping Transmission pan cooler

    2011.....always wondering if there has been a software update for the tcm to make it shift better...I bought this Tahoe 1 year ago, so I don't know if it has ever had any tcm updates. Has anyone here had updates done for the 6l80 tcm? If so, was it worth it, and what benefits did it do?

    Keeping Transmission pan cooler

    Had a thought if wrapping exhaust pipe that sits near transmission pan to keep transmission oil cooler. Is it worth it? Why or why not? Any better ideas to keep transmission pan cooler from exhaust pipe heat?

    Driveshaft vibration video

    Yes it's the rear driveshaft. So basically I should not use the Lucas heavy duty red n tacky grease to lube the splines? I have tried to move the driveshaft on level ground, and it won't budge, not even a little. The u joints seem to be new, but don't know how new since I bought it from a dealer...

    Driveshaft vibration video

    Keeping a tight spin under high rpms is right, that's what a driveline shop told me. Like spinning a top, when it loses speed, it wobbles. A guy working at advanced auto parts told me also when I'm accelerating hard, the vehicle will squat down and that's enough to correct a small pinion angle...
