    Electrochromatic Mirror Troubleshooting

    My mirror quit working. It’s the original compass one. I tested the mirror out of the truck and it works. I put a multimeter on the connector when disconnected from the mirror and get battery voltage. Start the truck, I get 13.x volts at the connector. When I plug in the mirror and read the...

    Correct 10.5" FF Axle Nut Socket

    Can anyone tell me the the correct tool for tightening the axle nut on a 1995 GM 10.5" Full Floating rear axle in my SRW K3500? The GM tool number is J-2222-C. I have KD-2770, but it has square lugs, not rounded ones. I'll probably end up just grinding on what I've got, but I'd love to know...

    7.4L 4L80e Locked During Shifts

    For anyone that has a L29 custom tuned, has anyone had the guts to try enabling the TCC to remain locked during a shift? I know it is enabled in the GMT800 trucks but that’s only with a 6.0/4L80 combo. I’m guessing GM left it disabled on the 7.4’s to prevent shock overloading the trans? I...

    1994 Chevrolet K2500 4x4 + Vortec Engine

    So my dad has decided to sell his truck. He’s owned it for the past 17 years. It’s in decent shape for its age and being a mid Atlantic truck. It’s still very solid. Still has plenty of life left in it for someone that likes these trucks and is willing to maintain one. Also for sale is a...

    Anyone have access to ALLDATA or the like? (GMC Jimmy PCM Pinouts -tow/haul)

    I’ve been poking around in my 2000 “black box” PCM tune using HPTuners and noticed it has a second shift table. After much googling the only thing I can come up with is a rumor that the GMC Jimmy in the ‘98-00 era with a 4.3L had an optional tow/haul mode. One statement eluded to that it might...

    Needle In A Hay Stack - 7.4L L29 Heater Bypass Hose

    I'd love to find the proper hose that connects the heater bypass valve to the intake manifold. I know I could just run a generic piece of hose, but for those of you that frequent pick and pulls that are full of GMT400s nearby maybe you could keep your eyes out for one of these: I could use the...

    Internal leaking intake manifold gasket, confirm my thought process

    So can someone please confirm my thought process. Background: 7.4L L29 Vortec, completely rebuild engine. Full back story here: https://www.gmt400.com/threads/andy%E2%80%99s-1995-cclb-7-4l-tbi-to-vortec-swap.45295/ After I put about 200 miles on it, I ran it WOT and then coasted down...

    Andy’s 1995 CCLB 7.4L TBI to Vortec Swap

    So I’ve been a member for a while now and have been working towards this swap for a long time. As I sit here mid project, filled with a bit of frustration, I’m thinking it might be therapeutic to do my own write-up. I’ll add to it as time allows. Comments welcome. If you choose to continue...

    Who’s crazy idea was this? (1995-1996 CC wiring diagram)

    So I’m getting really close to completing my drivetrain rebuild on my ‘95 cclb. The donor truck was a 2000 GMT400 reg. cab. Because of this I’ve found myself trying to merge the ‘95 interior cab wiring with the ‘00 instrument cluster wiring. Needless to say, I’m struggling. I think at this...

    What is this connector?

    Can someone please help me figure out where this connector goes? This is a 2000 gmt400 wiring harness. I’ve got the dash pulled down to better see it. I’ve looked all around and can’t find where there’s a place for it. Any help would be much appreciated! I’m stuck. Sent from my iPhone...

    Undercab Heat Shield Pics

    I'm in the process of converting my '95 K3500 CCLB from a throttle body 7.4L to a L29 Vortec 7.4L and was wondering if GM did anything differently after '95 in terms of heat shields for the catalytic converters. Could someone with a '96 - '00 take a picture of the heat shields around the...

    Anyone have this grille on their truck?

    I was thinking it might look pretty nice with the wire sections painted black? Just curious to see some pictures of it on some real life trucks. Sent from my iPhone using Tapatalk

    88-98 Crew Cab Nerf Bars

    I was wondering if anyone knows if anyone still sells nerf bars (3" polished SS type) for the 88-98 crew cab trucks? Would suburban nerf bars be the same? Thanks!
