My transmission pan is getting a little leaky. I want to drop the pan and replace the filter and gasket. When looking for a part number there appears to be two part numbers. One for a shallow Pan and one for a Deep Pan. How can I tell if I have a deep or shallow pan? Is there a particular...

well I found and can replicate the problem. Where the wiring comes through the firewall to the PCM I can squeeze them and cause the engine to stall, but only after about 30 minutes after the engine is good and hot. Any tips on how to troubleshoot or help figure out which one(s) it is and best...

Well its get weirder. I finally had some time to work on it. I did replace the ignition switch last week, but that did not resolve the issue. Here is the weird part. If I shut the front door or hood forcefully but not slamming it, the engine either revs up briefly or stalls. If I slam them...

Need More Ideas I couldn't get the dipstick tube to budge but I did get the nut backed off enough to get in there with a dremal and cleaned the ground and sprayed some electrical cleaner. Tightened everything back up and was optimistic. No smoke on start up, steady even idle. Let it warm...

I replaced the ECT and removed the optical sensor filter, starts strong, idles smooth, drove it around neighborhood, no problem. Headed to father-in-laws Saturday and 25 miles down the road it stalled again. I was monitoring ECT and Air Intake Temp. Both spiked to the same value of 300 when...

2 new clues I went to pick up the truck this morning and bring it home. No WTS light when I turned the ignition switch. I waited for the lift pump to finish cycling and it fired right up. Then the WTS came on for the second time. I am not sure what the normal behavior is for these things...

Well I was optimistic got to my daughters house truck ran great. On the way home it stalled again no codes. Pulled over luckily there was a street parking spot right off the street. I idled for a while and is stalled again. Just died no codes this died. Had my wife pick me up and will go...

I just had some time to look at this. Cleaned the ECM fuses - they were not to bad but not shinny clean Cleaned the Frame ground on the passenger side by the wheel well - It was pretty dirty I need to check the grounds on the rear of the transmission tube. Of course they are under the...

Will check fuses. I was thinking about replacing the ignition switch just to remove it from the equation.

Thank you.

Thanks - I am going to start with grounds. Yes used AC Delco thermostats. Have the original PMD as spare. Mounted the new one on the skid plate. No more clues yet other than the weird coolant temp reading.

Hello, Need some help for my 96 Suburban. I bought it last year and it has been nothing but trouble. I got it tow my small trailer and boat and snow vehicle in the winter. I have used this forum to learn about it and guide upgrades and fixes. So far: Heath PMD Heath Turbo Controller...
