    1999 C5 Corvette no speedometer

    Great tip! Wouldn't be a bad idea to add a diagnostic connector in the cabin when I find the wire under the dash in. I'm hoping it runs through the electrical center... Seems that I diagnose this further, the PCM runs serial data (with vehicle speed in the data stream) and a standard vehicle...

    1999 C5 Corvette no speedometer

    Thanks @exp500 I have a miniature scope. Would be perfect If I could find out how to tap the line in the footwell.

    1999 C5 Corvette no speedometer

    It's official I'm stupid. Those are TWO separate connectors. I thought they were two sides of same connector. Still any tips to diagnose Vehicle Speed Signal are greatly appreciated.

    1999 C5 Corvette no speedometer

    About to cry. I have my hot rod stored for years. The bleeping battery boiled and leaked on wiring. I've got most of it all fixed up. However, the speedometer will not register. It passes self check, and scanner shows a good VSS signal to PCM. However, the signal is not making it from the PCM to...

    Portland Electric Pressure Washer Hose Specs???

    @adventurenali92 AWESOME, exactly what I needed to know. Thanks! I'll go to Home Depot and pickup the parts :) @Sam Harris dang, now I find a video on YouTube that explains my EXACT concern. The pumps are good, the hoses and guns are junk from Harbor Freight. I believe there must be a factory...

    Portland Electric Pressure Washer Hose Specs???

    Yeah, the locking cam end of hose is what I cannot find an adapter for. I'd like to adapt that to a quick disconnect setup.

    Portland Electric Pressure Washer Hose Specs???

    I've owned a few of these electric pressure washers. They work great for cleaning a car. Not too much pressure they strip the paint off. Long story short, where they're TERRIBLE is in construction of the sprayer. The bleeping sprayer always goes bad. I bought a different sprayer to try and use...

    Pulling off the Perfect NP246 Transfer Case Rebuild

    I need part numbers for the input shaft snap ring (that goes on hub for gear hub / input side)... And the output shaft. I'm nearly completely done but those two snap rings are loosey goosey. UPDATE: I found the part number it's GM 682653. Looks like both the planetary snap ring and front...

    2005 Tahoe Towing

    What year is your Tahoe? I don't think GM put a transmission temp gauge in any of them but could be wrong. I swapped out my cluster with one that has trans temp. SUPER helpful. FYI ~ On fluid, others may not agree with me... However, I don't change it out that frequently anymore. I used to do...

    Transmission!!!

    What was wrong with it? Did you ever find out? Did you drop the fluid pan or check the dipstick?

    Rear lift gate glass hinge seperation?!

    I'm still in need of repairing mine... I have a terrible habit of leaving things unfinished. I bought the 3M windshield glue. It's on my self ready to be done...

    Water in edge protection of hatchback

    What is the year and model of your vehicle? I don't see a pickup in your picture... Do you mean hatchback? You shouldn't have any water in the hatchback, at least not that much. That's super weird. There's two weep holes at the bottom corners of the hatchback to drain. They have little rubber...

    Pulling off the Perfect NP246 Transfer Case Rebuild

    Ooops haha I just ordered from merchant automotive. Your suggestion would have been more affordable. It was only $3.99 however shipping was $16 so I threw magnetic train and fill caps.

    Pulling off the Perfect NP246 Transfer Case Rebuild

    I did a final sanity check on the clutches. The new clutch stack is within 5 thousands of old one so I think good enough. I'm assembling and is very easy to put it all together but ran into a hiccup. The snap ring for the gear selector is no good. It barely hangs on the shaft. I'd replaced that...

    Transmission connector broke on 4L80E

    Thanks! I like the idea of butt connectors that seal up. Seems whenever I solder a connection and use shrink tubing it seals up but the solder joint eventually fails no matter how I solder it. I'll advise accordingly. Doesn't seem to tricky if is similar to 4L60E. Anybody worked on these older...

    Transmission connector broke on 4L80E

    Oh that's not too tricky. Maybe easier to just swap out the whole harness. I know there's different pinouts between different years. I used to have a chart with all that stuff but cannot recall where I saved it.

    Transmission connector broke on 4L80E

    @Eman85 could you get to the entire harness when you dropped the pan? Or does it require more? I've only done a 4L60E. Not sure if it's similar?

    Transmission connector broke on 4L80E

    Maybe... I go to junkyard here quite a bit and never see trucks that old. Most of those of that vintage here have been crushed. I think rebuilding the actual connector itself is the route to go. Otherwise, replacing entire harness, but that would require opening the transmission. I've done a...

    Transmission connector broke on 4L80E

    Yeah, kind of what I feared. It's likely not made anymore, only found in old forgotten parts bins.

    Transmission connector broke on 4L80E

    Ah good, I couldn't quite tell what was wrong in pictures. Also never saw a harness like that. Actually looks better than new design with that screw. Do you of a transmission parts distrout or that still sells these?

    Transmission connector broke on 4L80E

    I have a friend with a 1993 3/4 ton Suburban. It has the 454 and 4L80E transmission (or heavy duty). I don't know much about these years or those builds to be honest. I maybe way off. They sent me pictures, it looks like the transmission connector broke off on the engine / chassis side of the...

    Lost rubber seal for my TPS connector

    You're a lifesaver! Thanks :)

    Lost rubber seal for my TPS connector

    I want to scream... It was one of those honest mistakes. You know if you drop it you'll never find it so you're careful and it happens anyways. The rubber seal on the end of my Throttle Position Sensor connector fell behind my water pump. I don't have any way to get it back out lest I pull the...

    Strut mounts replaced correctly?

    Okay so this is going to be confusing to explain. I also have a video below as well as pictures of what the replacement mount looks like. https://photos.app.goo.gl/jfXzhatnWp55tkum8 There's a profile / ramp where the spring seats on it. This ramp floats. It didn't on the factory mounts. I'm...

    6.0L Fuel pump?

    Gotchya, I may run the fuel pressure regulator test again. I already had them pressurized just on the fuel rail. I don't think I should have seen any fuel coming out of injector at all... I'd assume they're bad (not dirty) since it's been hard starting since I installed the injectors new (built...
