    Proportioning Valve compatibility JIMMY to C1500

    I couldn't find a c1500 where the front wasn't mangled or where the proportioning valve was already taken. I wanted to remove it because I've got to have the abs bled (air) and bad pedal. I guess i just don't like dealing with it anymore, and just wanted to simplify the brake system. One option...

    Proportioning Valve compatibility JIMMY to C1500

    If someone can, give me the number that is etched into the side of the proportioning valve on your your 88 - 94 C1500. I'm hoping it'll match the number from above. C1500 rear brakes are slightly larger in diameter (.5") and width (1/4"), rear cylinders also larger (1 3/16 bore vs 7/8 bore)...

    Proportioning Valve compatibility JIMMY to C1500

    Hi, I have a 96 Cheyenne 1/2 ton pickup with the 4.3 V6. I want to remove the abs unit. However, I have not been able to confirm if the proportioning valve I pulled off a 91 Jimmy (not sure if S15 or not or 4wd or 2wd matters or not because I am not sure what trim it was) will work properly...

    4.3 Blazer and 4.3 C1500 Radiator Cap Interchangeable?

    Hi Guys, I've been experiencing not fully heated coolant (stays about 170F). Now, I looked at GM recommendations due to Dex cool contaminations and said best thing to do is switch from drop center radiator caps to spring center radiator caps...

    4L60E P1870 Code. Repair questions

    Hi, I'm back to revisit the issue. I think I want to try fixing my trans myself and swapping out my "black box" to a 411 PCM. Just sounds like a fun project and a chance to learn more about transmissions and wiring. I also want to run the 4.3 a little longer and have the fun of tuning it for a...

    Grand Plans for Transmission! Need Advice

    Searched craigslist, found maybe 3 or 4 potential used trans (not rebuilt) from around 300-500 dollars ranging from 50k to 86k miles on them. Might be able to recoup my costs later by reselling (I only drive about 12k miles a year so thats average). A couple of them have short warranties so...

    Grand Plans for Transmission! Need Advice

    Should I try finding a cheap ass used 4l60e to swap from a junkyard in so I can use it for another year while planning a ly5/lm7 swap? What year trans should I look for that will work with my PCM without mods? Oklahoma currently does not have any laws regarding engine swaps as far as I know...

    Grand Plans for Transmission! Need Advice

    twomany... I hadn't given that much thought at all. Added my location to my profile. Don't think it is a problem in Oklahoma but that is definitely something I will look into. If it is a problem, well I guess I'll have to stay out of trouble after doing the swap! BTW, I wanted to ask if anyone...

    Grand Plans for Transmission! Need Advice

    Man, I am having a hard time making a decision. I really want to put a more powerful engine in the truck. Right now I absolutely think the 5.3 LY5 is the best option for me in terms of the power and minor towing capability while retaining decent fuel economy. But what if the new 4.3 with the 6...

    Grand Plans for Transmission! Need Advice

    Hello all! Hope you are all doing well! I've recently had a failure with my 4l60e transmission. Now, I'm pondering a couple of choices. I'm keeping in mind my long run plans for the truck. I eventually want to have a 5.3 or 6.0 engine swapped in there. I've heard rebuilt transmissions...

    4L60E P1870 Code. Repair questions

    Extra clues. It has no reverse and now makes a terrible duh duh duh duh duh duh noise. I'm pretty sure it's toast. I am going to search threads related to 4l80e to 4.3 vortec swaps and see what I can find. If anyone knows a good thread (not necessarly only on gmt400), please post it. I'll need...

    4L60E P1870 Code. Repair questions

    ah S%!+, No way it might just be a A or B solenoid? (not sure). or anything else? I might just take it to a tranny shop but I want to ask this. I'm thinking about putting in a 4l80e instead of rebuilding this one. I plan to swap in 5.3 or 6.0 down the road when the engine goes kaput. The engine...

    4L60E P1870 Code. Repair questions

    I am not sure about the low gear part. I think yes. I would take off slowly and it wouldn't shift until something like 2500 RPM at ~20mph. So I'm assuming it stayed in 1st until it was traveling fast enough to go into 3rd. I have not driven it since parking it. Should I go drive it? What should...

    4L60E P1870 Code. Repair questions

    Yes, P1870 was the only code that was shown. I was getting on the hwy, it went into OD momentarily then violently shifted into 3rd. I actually thought I had been hit from behind... Went 20 miles this way. Drove 55 in a 75 to keep the RPMs down to 2000 (which means either slipping badly in 4th...

    4L60E P1870 Code. Repair questions

    If this helps, the replacement part I am looking at is the Teckpak A74741Q. It is said they may have a way to replace this part without removing the valve body. I will contact them and see what they say about this. If anyone can chime in on the questions that would be great and really help me...

    Hi, Truck went in limp mode. Had to drive about 20 miles at 55 mph this way... Pretty sure tranny fluid burned a little during this. no matter have to replace anyway now. Pretty sure P1870 means Torque Converter Clutch Isolator valve. Found a replacement part that doesnt require any...

    Truck Stalls in the Morning - Help me diagnose the issue

    Did cleaning of MAF when I had cheap distributor parts on causing misfire problems. Good quality ACDelco rotor and cap fixed it. Was about 6 months ago. Could this issue be creeping back up again? I don't think so because back then it did it at all speeds, hwy and during acceleration. I will...

    Truck Stalls in the Morning - Help me diagnose the issue

    Took a while but got around to it. Tried cleaning IAC valve and new valve. No discernible difference between the two. Still does it. Taking IAC back to get $ back. Funny that you say Intake Manifold Gasket leak. I just replaced the IMG because of a coolant leak. If I remember correctly, I did...
