    Crank-No Start 99 Tahoe 4x4 5.7

    I'm having an intermittent crank-no start on my truck. This seemed to develop over time when the truck would crank slowly almost as if the battery was dead. One evening the truck died for good and couldn't be jumped so in went a new battery. This did not solve the problem. A few days later the...

    Fresh rebuilt NP246. After switching to 4Hi and hearing a ping or pop from the case, it is 'stuck' in 4Hi an will not return to 2WD or 4Lo. New switch was installed along with new encoder motor at the time of install. Usually ran it in 4Hi for a little bit every week to move things around - but...

    New codes and drivetrain issues after getting stuck

    Misfire Cylinder #5 after warm-up - possible bad spider?

    Hey guys, I am trying to troubleshoot an apparent misfire on cylinder #5 on my 99 2 door Tahoe. The problem only occurs under load, and after the truck has warmed up. It has had the newer style MPI spider installed for almost 5 years now, and the shop near me thinks it's a bad injector. My...

    VSS going haywire on new/rebuilt Transfer Case/Tranny

    Hey guys, just finally getting my truck back out on the road yesterday when it definitely was having a major problem. The transmission was acting very bizarrely - shifting only into 2nd and downshifting back into first on application of throttle. In addition to this, the transfer case fuse blew...

    99 OBS Tahoe Transmission options with 4L60E

    Hey guys I'm curious which of the two piece model 4L60E can be controlled by the 5.7 Vortec PCM? Am I right in assuming that up until about 2004-2005 will work (green plug)?

    Centric Drum Brake Parts Kit Issues

    Have any of you guys used a Centric parts kit? Reason I ask is that I have used them now twice on my rear drums, and both times the c clip/pin has come off of the parking brake bracket and the entire drum has grenaded. The clip that these parts come with is nowhere near as beefy as the OEM clip...

    Howling/Wooshing and no power

    Hey guys, Just wondering what this may be. The truck will make a wooshing/howling sound in first and second gear and almost feel like it's not wanting to make power but RPMs climb. This doesn't sound like a driveline whine, it's amost as if it's blowing air. It sounds almost like some of the...

    Treating/blasting frame rails

    Hey guys. I'm curious how any of ya'll might have gone about treating or blasting the frame of the truck for rust and corrosion..... with the body on or only slightly detached?

    Drivetrain locked up in truck! & Transmission interchange question??

    Hey guys... Driving thru a parking lot yesterday and got a pretty nasty grind for about a second or two then complete driveline lock. Removed the driveshaft and truck was able to roll.

    Transfer Case woes

    Hey guys, there is a pretty gnarly sound coming from my transfer case. It's pretty much sounding like the world is ending inside there. I'm not sure if the chain has stretched or if something broke. It runs/shifts/drives fine with the exception of the case. I hardly ever use 4WD and drive 99%...

    Odd condition, random misfire, no power under load, bucking, dying...

    Hey guys. Chasing an old condition that has now come back with a fury. The truck has a chronic low/no power condition on warm start, off idle. If I'm trying to exit a parking lot, or turn across an intersection, this can be a bit perilous. Essentially, the truck has no power when applying...

    Destroyed power steering pulley.

    Hey guys just curious if there's any good ways to get the PS pump off without removing the pulley? I pretty much just destroyed it using a puller tool. The snout has pretty much sheared in half. Are the bolts behind it accessible enough to get out with fingers? I can get a wrench on them and...

    Hey guys just wondering where all I use RTV in the longblock. About the only place I know for sure is at the top of the bulkhead where the intake sits on the block and around the front part of the oil pan. Any help is appreciated. Thanks!
