    gear shift indicator light

    The black part you are looking at is the shift interlock solenoid. All it does is prevent the gearshift from being moved out of park unless the brake pedal is depressed. It may have been unhooked due to it not working correctly (probably bad solenoid or brake light switch). Won't prevent...

    Crank relearn and cam retard offset question

    Yes absolutely. I don't think the crank signal just changed all of a sudden. When I got it tuned I also got a new computer. So I just wanted to calibrate it to get it used to my engine

    Crank relearn and cam retard offset question

    I was able to borrow a scan tool from a shop and did the crank variation learn. Checked the CMP and still within spec. Engine is spark knocking a lot though when put under load. Wasn't doing that before the computer swap and I haven't messed with anything else. Guess I'm going to get in touch...

    Crank relearn and cam retard offset question

    I can read the CMP with my scan tool, it just can't do crank relearn. I guess I will get that done first and then check CMP when I get home just to be sure

    Crank relearn and cam retard offset question

    Working on my 2000 C2500 5.7 (now 383). Ordered a tuned PCM and installed it today. It runs, no check engine light, but I understand doing a crankshaft position relearn is recommended. I set the distributor offset to 0 (+/- 2) degrees @ 1000 rpm on the old PCM. Do I need to readjust this for...

    There are lots of aftermarket ones on ebay but not with that exact part number. Looks like the same thing though...

    Chrome front bumper guards

    Those aren't a direct fit though. I wonder what would be involved in modifying them

    I can't seem to find them. Do you remember what section they were in or part number?

    2000 C2500 Project

    My new exhaust has been noisy since I first installed it. Found one of the clamps before the muffler was not sealing well. The muffler itself was leaking between the body and pipe entrance. And the intermediate flange had blown the gasket out. The clamped-on tailpipe did not want to come off the...

    Chrome front bumper guards

    I didn't know GMT400s had these until seeing some pictures recently. Really like the way they look. I'd like to get something like this for my truck. From what I found on the forum, looks like a company named GEM used to make them with the part number 653L118. I wish they used studs and holes...

    Truck won't shift out of park

    That's not always accurate. One went bad on mine and the lights would come on, but the shift interlock solenoid would not release and could not shift out of park. New switch fixed it. If it's solenoid related you should still be able to shift with the ignition off (not lock) as the solenoid will...

    Any tips on getting the spider connector to seat into the upper intake?

    Yes start with plenty of lubrication. Make sure you set the intake flat and straight on top of the spider. Rock it front to back and side to side while pushing down. With throttle body removed you may be able to reach through the hole to put some upward pressure on the spider while pressing the...

    2004 Impala LS (3.8L) Questions

    The inner fender has a slot for a speed nut and bolt to hold the washer fluid neck. But I have also seen many with just a plastic push in retainer. Not sure if the factory changed it after a certain year or if it's from people working on them and losing the nuts at some point

    4L60E going in and out of lock up Help Please

    I believe that switch also has a set of contacts that control the TCC. Might be worth a try

    It goes on the stud behind the head that also retains the wiring harness bracket and ground strap.

    2000 C2500 Project

    Thanks. It's definitely better than the worn out 350. I had a few problems at first, low oil pressure and transmission not shifting. Both were because of brand new, faulty sensors. I thought Standard Motor products was supposed to be a decent brand. And then I had to pull the upper plenum back...

    2000 C2500 Project

    I apologize for the dust on the valve covers, it's from all the pollen lately. I removed and capped off the air intake resonators. Cleans up the engine bay and it sounds a little louder now. You can hear more of the wooshing sound when opening the throttle, not the same as a quadrajet but...

    2000 C2500 Project

    I finished putting everything back together a few weeks ago but wanted to share some pictures. I didn't feel like painting the manifolds initially but they look really pretty after I did. I spent many hours with the driver side one getting out a broken off stud and stuck donut. Would've been...

    Metering body gasket trouble

    Well I made a spacer out of an old metering body bracket and changed the bolt but later decided against it. In order for the bracket to self-align to the intake like factory it needs to have a little wiggle room. And if the bracket can move, so can the spacer, and I don't like the idea of a...
