N8in8tor, The pictures side by side I just dropped in and drag the corners to where you want them. I didn't really have to do anything special I noticed. JMJNet, I don't think there is a better equipment for replacing the transistors. Soldering the pins to the board is as good as the OEM...

Sorry I didn't feel like editing a video or uploading it, but you can see the alternator cooling fan is obviously spinning. I know anyone could pop the covers off of the transistors and hook up a new PMD to show a truck running. Put your covers transistor covers back on your PMD and put it in...

8) Apply a bit of flux to each pin to help the heat transfer into the transistor lead from the soldering iron and solder the transistor leads to the circuit board. Just a tiny ball of solder on the tip of the iron is sufficient to solder the connection and will travel down the lead to the board...

Okay guys, I finally had a chance to play with some PMDs. The first one I repaired was a 2 beer job. The second without pictures was 10 minutes (could be 2 beers if you so choose). Both worked upon plugging into the truck in the block below. Both did not work prior to. This repair replaces...

I've been an aircraft and heavy equipment mechanic for 20 years. I'm not trying to reinvent the wheel, just keep it rolling. Never fear, I'm not going to put a starter in the valley!

Hi, everyone. I've been away for a couple of years obtaining a mechanical engineering degree and working full time, which didn't leave much time for fun things (as in zero). Well, that's all over with now, and I have time to play. I have learned tons of stuff from this forum over the years...

Found the little culprit. Wire broken but the coating was not about 1 foot from the trans pass through connector. Cleaned it up, soldered, and heat shrunk. SHifted into OD like a champ. Still shifts into 2nd really hard. How can I adjust that?

Truck shifted beautifully before doing electronics in the trans except for no torque converter lockup. I am putting it back together again today and I will let you guys know what is up. If I need a PCM I'll let ya know, but this one tested fine. It sounds like a good deal tho'. Thanks for...

Does anyone have a mainfold pressure switch laying around that you can check the resistance between the pins. I can't find anything online or on AllData for a check for it. Thank you.

Troubleshot all of the wiring to the trans from the pcm and found an enomily in the internal harness to the manifold pressure switch which was replaced. Had to drop pan again to see if it was pinched wires in the harness or the actual brand new switch. Two pins on the switch had continuity...

Test drove. No change.

trans input speed sensor which is hooked up reads 1.517k and 1.458k for output which is not used. Swapped for its and grins.

Removed vss. Very little metal flakes. Cleaned. Ohmed out at 1.41k ohms. What is it supposed to be?

Speedo is working fine, but the cruise has been working intermittently. I guess I am partially inept. I need to put the vehicle on jack stands and run it while checking the voltage or resistance from the sensor on the transfer case? By the way, doesn't it seem strange that all of this would...

Where are the VSS at?

Another question. There is some type of sensor above where the selector lever and it's respective electronics are. There is another identical looking sensor located at the aft of the trans. What are these? The one on the rear of the trans has no plug connected to it and looks like there...

Just hooked up gmtd scan and it confirmed what I thought. When I selected 1st it would shift up to 2nd. WHen I selected 3rd, gmtd said it shifted into 4th. But when I shifted into D, it shifted again. So I know that it couldn't have been in 4th. Is there just speed sensors that gmtd says...

I'm getting so tired of this truck. All I do is work on the darn thing. I replaced all of the electronics in the trans and now it shifts into 2nd very hard. Not to mention that other gears also, but it is hardest into 2nd. I also installed a deep transmission pan and new filter. I...

I just bought a pop tester and rebuilt my injectors. It is really not a bunch of fun to play around with. Lots of trial and error. Maybe if one was not on a time crunch, but I always am. For the price that moneyslave sells his brand new bosch injectors for, it is well worth it. Remember...

I'm looking now at used OEM. My originals were corroded to the injectors when I replaced the heads a few years ago. I always thought I did something wrong or didn't torque the lines enough, but it was crappy injector lines all along. They were always wet around them. Man I hate doing the...
