    Please help! Rebuilt 700r4 rolling while in park/all gears.

    No, driveshafts are not yet installed. Why would that make any difference?

    Please help! Rebuilt 700r4 rolling while in park/all gears.

    I have confirmed adjustment of the shifter linkage with the shift shaft and it goes through each gear properly however I don’t know what it’s doing or not doing inside the transmission. Shifting feels “notchy”, as normal.

    Please help! Rebuilt 700r4 rolling while in park/all gears.

    I bought and installed a rebuilt 700R4 automatic transmission into my ‘83 K5 4WD and a new GM crate SP350 and am in the process of trying to start the engine for the first time for break in purposes. When I pushed the truck out of the garage to attempt a test start of the engine, I noticed that...

    Dreaded radiator sizes

    I bought a Cold Case radiator for my ‘83 K5. I had to heavily modify the upper metal mounts to hold the radiator and upper fan shroud in place.

    Here’s the best heavy rust dissolver for smaller parts like nuts and bolts that you’re probably not aware of and is probably in your kitchen.

    You might want to compare it to the 80% strength vinegar that I used to see which works best on heavy corrosion. Common vinegar is only 10% although citric smells much better!

    Rust removal

    80% Vinegar the best to remove heavily rusted and pitted parts. It’s much cheaper than automotive type chemicals, less harsh and easier to filter, reuse and dispose of. Here’s the link to my post...

    Here’s the best heavy rust dissolver for smaller parts like nuts and bolts that you’re probably not aware of and is probably in your kitchen.

    I try to use less chemically harsh solutions for dissolving heavy rust and old paint through soaking parts like nuts and bolts and I’ve tried darn near every rust neutralizer and acid chemicals on the market that are also harder to dispose and of course have used diesel fuel. Several years ago...

    ‘83 K5 350/4wd: aftermarket oil psi switch/sender/choke heater wiring question w/pics and schematic

    Okay, along with my other post, I think I understand what you and @EvilGenius are saying. I must have misinterpreted the colored ClassicCarWiring.com diagram that says “Oil PSI SW (6 cyl w/o gauges-see pic) as meaning it was only specific to 6 cylinders (thus this separate post asking what to do...

    ‘83 K5 350/4wd: aftermarket oil psi switch/sender/choke heater wiring question w/pics and schematic

    Okay, I understand your explanation and is the way I understood it in my head, thanks. The Haynes manual (see photo) shows the DK Blue wire (from switch) connected to the LT Blue wire (from choke) at the switch and from the switch, the DK Blue wire connected to the Tan wire that goes to the...

    ‘83 K5 Wiring diagram V8 vs V6 Firewall Block blue wire for oil psi switch requirement??? See pics

    I also posted another question/scenario that may comply with your response. This post is specific to the blue (schematic dashed) 931 wire that goes to a “Oil Psi switch (6 cyl w/o gauges)” as shown in the pic of the schematic. I may have already satisfied this requirement as explained in my...

    ‘83 K5/350/4wd question: Please confirm my wiring/splicing is correct per the Haynes manual schematic.

    ‘83 K5 Wiring diagram V8 vs V6 Firewall Block blue wire for oil psi switch requirement??? See pics

    ‘83 K5/crate 350/4wd: I am redoing some damaged wiring. The electrical schematic I have shows a blue (dashed) wire from the firewall block to an oil psi switch (6 cyl w/o gauges). I’m not entirely sure if this wire was connected to anything before I pulled the factory 305 to install my new crate...

    83’ Blazer: In need of a factory muffler heat shield

    A catalytic converter is not required thus my reasoning to remove that heat shield. What do you mean by “up to 300 HP”? My engine is a 385HP SBC350. Is a single 2-1/2” or 3” exhaust not enough flow or do I really need dual exhaust to get enough flow?

    83’ Blazer: In need of a factory muffler heat shield

    Thank y’all for the input. I may very well try to find one in a junkyard since I’ve exhausted all other resources. However, I did find aftermarket heat shields that attach to the mufflers as another possible option. Let me ask you another question, since I am considering installing true straight...

    83’ Blazer: In need of a factory muffler heat shield

    Mine was a factory 305, but I installed a new GM crate 350. Just thought I would see if anybody had another heat shield so I could run dual exhaust. Thanks for the reply!

    83’ Blazer: In need of a factory muffler heat shield

    1983 Blazer: I am in need of a factory muffler heat shield for the right side for dual exhaust. I’m assuming that my Blazer originally didn’t come with dual exhaust and is the reason it didn’t have a heat shield for the right side. I’ve been looking online but can’t find one. I’ve checked AMD...

    Can you believe this???!!! TC/NP208 Adapter/700R4 trans crossmember mounting/question?

    I just wanted to provide a follow up to this post. I have called multiple reputable 4WD specialty companies around the country and was told that SLE’s are no longer manufactured for NP208 transfer cases. I was also informed that with a 4” lift that with the proper aftermarket ORD adapter mounts...

    Help with difficult problem!!! ‘83 K5/4” lift/NP208 mounting height with incorrect homemade spacers vs correct spacers???

    The 7/16” bolts did work. Not sure why the bolt holes were grinded open for 1/2” bolts to be installed. Thanks for all your input!
