Howdy guys, my dad is finally driving his 2011 GMC Sierra SLT 3500HD DRW. (When he started a month ago, it had about 1,100 mi on it...it's lived a sheltered life. ;)) It has the XM/Bose radio and the rear view camera, NO rear seat entertainment. He wants the factory nav radio, I know it will...

I would appreciate it if any GMC owners could take a moment and measure the length of their exterior body molding if it matches the style I have shown. I realize that I omitted the 3 door cab trim from 99/00, I do not anticipate needing that dimension. Additionally I realize there is a lot...

I have a 2wd NV4500 removed from a '93 C3500 SRW truck, and I will be putting it in my '83. I am trying to figure out what all parts I will need to convert it to a 4WD version. I have the rear housing and the mainshaft. I am trying to find a balancer for the mainshaft that does not cost an...

I am tinkering on my boss' new (to him) 1993 Chevrolet Cheyenne K2500. It has 170k miles on a 6.2L N/A, 4L80-E, NP241. It runs GREAT, it starts right up as soon as the Glow light goes out, it is an ex-Fire Dept. truck and seems to have seen regular maintenance. Reverse is out in the...

I need to swap the shift shaft out on a 4L80-E, and to remove the retaining pin the plate under the valvebody has to be lifted...meaning I lift the valvebody. If I have the transmission perfectly upside down, blocked, with the valvebody on top, can I lift it off, do what I need to do to the...

Howdy, My boss is looking at getting a 1993 K2500 6.5/4L80-E and the transmission is bad. We have a Goodwrench Reman 4L80-E with low miles that was removed from a 1995 K3500 6.5 truck. I have read that there are possible valve body mods &/or changes that need to be made to the harness...I...

GMT-800 DRW rear clearance light: I had this for my '07 but since that isn't going to happen I wanted to put it on something. I installed it this last weekend, centering it and filing the holes to the proper square dimensions for the OEM clips that I purchased with the light. David...

Patrick, I recently had the interior apart in a GMT-400 truck and I am reminded of a recurring problem for that series of truck. From 95+ the Hood Release Handle is a notorious pi**-off. There is one bolt and a plastic tab that hold it in. I have seen that bolt hole break out more often than...

I would like to get away from lead weights on my wheels, either stickies or clip on. I thought I read on TTS in a signature where someone was running one of the balancing medias in their tires. I am looking for testimonials/opinions on that kind of product. EDIT: Looking into this for both...

Problem: Cranks, coughs (half-sorta fire), puffs a little exhaust, does not start. Demographics: - Year: 1999 - Truck model and class: K2500, 8,600 GVWR - Automatic or Standard: NV-4500 - Mileage: ~146,2## miles - Replaced parts and mods (IP, PMD, chip/PCM, TM, injectors etc): PMD replaced...

Can anyone provide a good solid writeup on deleting and bypassing the glow plug controller card? Specifically an '86 M1008 CUCV. Would like manual control over the glow duration.

Hey guys, wasn't sure if I should put this here or in Exterior. The driver's side mirror on my truck isn't defrosting. I drove around for 15-20 minutes the other day with both the front and rear defrost on, nothing. It is currently snowing like the dickens and I am not inclined to go look...

We're talking big boy M1008/1028 CUCV here, not the Blazer. I know it has ran in the past. I think the batteries are probably a bit low today, and I know it's got a problem somewhere in the glow plug controller/relay/thingy. It was jump started with an M35 last year sometime, so I know it...

My dad and I like to collect vintage tools, he has been at it quite a bit longer than I have but if I see something somewhere I'll try to snag it for the collection. He recently was given a medium sized tool chest with various tools in it. Most of them are el-cheapo imports and all of them...

David (88gmctruck) and I are helping a friend do a tuneup on her SD, IIRC it has ~170k on it. It idles pretty rough and we pulled a plug to look at it, both electrodes were worn and the insulator has a hot spot. I am looking for anyone that has worked on these things. I read in the other '99...

Ashton, here is my latest one. Previously you were kind enough to give me some advice here. I ended up changing my oil then, at about 37,868 miles. At that time I also cleaned my air filter out. My latest analysis with 10,200 miles on DEO & AeO52 shows copper at an elevated level, though...

I peeled this pic off of autoblog.com, anyone else see it?

Problem: Explain your problem in concise language Throws engine codes 32 and 33 at unpredictable intervals (usually when traversing steep, unpaved terrain), and engine RPMs occasionally spike without touching the accelerator when manually switching gears and when braking or releasing the...

I'm going to peel a few things out of the archives of DP for reference here since this has been brought up lately. Credit goes to all original posters for the information. Later on in the thread that post was taken from Mike shared the article from Transmission Digest. I dug around on the...
