    6" Skyjacker lift on a 74 K2500 long bed with driveline vibrations

    My build is NOT 6-inch lift... The 4L80-E and the 14-bolt rear mod did pose significant spacing issues similar to what you are dealing with though. Try this: Spicer Driveline App angle finder: https://spicerparts.com/calculators/driveline-operating-angle-calculator And this: Toolbox TREMEC...

    14 Bolt 10.5" Rear Axle -FOUND-

    Don't turn down a newer axle... if you can find one. Just not too new... Can you cut/grind the perches off a 1997-ish and up GMT400 and weld on longer than stock perches where you need them? Worked on my build.

    Where's the resistor in the coil pink wire from ignition switch?

    Coil resistance not tank fuel gauge resistance Turbo4whl... LOL I'm sure I need that info just not yet... LOL! My attempt ton increase the guage of the fuel electrical power circuit is still in the works because they routed like crazy people through the fuel pump and oil switch without...

    Where's the resistor in the coil pink wire from ignition switch?

    OK, full 12v it is. So much confusion on the internet. Really appreciate Old Guy Bill, Ali-c20 and Craig Nedrow.

    4L80E fresh rebuild, no reverse. **UPDATED DEEP PAN MOD ISSUES**

    The Brand name filter came in. After cutting it open, it has similar internals. The sale page mentioned something about an added screen to the filter layers, however there is no screen in this one either. Because I do not know the exact flow path in either filte, in the event my comments were...

    Where's the resistor in the coil pink wire from ignition switch?

    Thanks for the input. The AI algorithm states the resistance for the points distributor is 1.5 OHM, while the TBI system switches between full 12V during starter relay ignition, then switches back to the resistor to 1.35 OHMS. (NOT 1.5 ohms as in the ceramic resistor systems of the past). It...

    Where's the resistor in the coil pink wire from ignition switch?

    Yes and where specifically is it? Between the ignition switch and the fuse box? Between the box and the coil? Memory working... YES Please!

    Where's the resistor in the coil pink wire from ignition switch?

    My new relay circuit for the new column is wired and ready to install. It means cutting the OEM switch connector and using the new three relay circuit. My question: Where does the resistor live in the wiring harness for the coil pink wire circuit? Is it in the wire? Is it in the ignition...

    4L80E fresh rebuild, no reverse. **UPDATED DEEP PAN MOD ISSUES**

    This is getting interesting... Contacted the company that sold me the sweet billet and stainless filter re-location kit, ($290.00). They said they don't have any affordable or steel covers that fit the system they sell. $470,00 for the pan they offer seems a bit steep. So my best option was...

    Sanden compressor wiring

    Zener Diode for fly-back protection. Should not interfere with 12v to your meter if the switch is activated. If you have the 1989 dash controller you may have an electrical circuit for A/C with the three dial controller? It will get activated through the computer with an RPM bump on your 89'...

    Ididit Column Swap

    No welding will be required now the lower ball column shaft is swapped out. Here's the high Ratio Gear installed. It required some hard washers for stand-off with the frame stiffener plate Welded in there. They do not ship them, so plan on having some that fit the machined circles in the...

    4L80E fresh rebuild, no reverse. **UPDATED DEEP PAN MOD ISSUES**

    Well it's been a very long time since I posted this list of parts for the deep pan solution. Nearly 5 months. When I crawled under the truck, drained the oil, installed the awesome rear sump filter mod, from SD Concepts, it fits great. The Black Pan from CFR does not work. The exact space the...

    Ididit Column Swap

    Tore down both columns. Was able to swap the 40 spline bottom shaft into the Ididit column. The lower shafts are interchangeable. You can see the Delryn bushing mod for the old column. Ididt's version is similar. Black Delryn? Did not check to see if there's a bearing down there... maybe...

    Factory 4L80-E transfer case push rod?

    Anyone have the top one sitting on a shelf with good threads? Rather not cut the OEM 700R4 version, however when I locate it, it's available for a swap. It's here in one of the fifty boxes we moved twice.

    Transfer case shifter rods

    That works for me. My 700R4 to NP208 was slated to cut and weld to the longer spec. 4L80-E to NP208 is approximately 1-3/4" or 1-11/16" longer due to the 4L80 larger case. The part numbers help. These guys used the top part number for the shorter version on this website...

    Ididit Column Swap

    Here's a side by side of the upper column from Ididit's older version and the 87' OEM unit: On the lower left picture, you can see there's a small rectangular extrusion in the plastic casting near the OEM ignition switch. Not sure it's possible to grind that polymer away and re-use the OEM...

    Ididit Column Swap

    Obtained an Ididit column for the 87' Blazer. Since this unit is about 5 years old or more, thought I'de take some pics and explain the internal differences between the OEM column and the nice-r stuff. First off, this unit has a different shaft and is a lil' bit shorter than the OEM GM...

    Steering box

    My first Gear came stamped with the Blazer as a REMAN. It never worked correct in 6 years. During the engine remanufacture I opted for a supposed new unit from a Missouri eBay store. Still had significant 2 inch slop and the dreaded low RPM worse than manual nightmare steering. When I reached...

    1988 Camaro

    The Military used razors and gas barbecue grill titanium flame plates as an insider technologies consumer marketing program to cut the cost of Govt related parts for manufacturing.

    4L80E Information Thread

    Cool. :cool: Make 2? Make one for me, AuroraGirl... ? The small plate comes with the kit. So I have that one. The bigger ones are way too expensive for my budget. They make VB testing much easier. I'm out of plexi. The eBay seller offering the great price had the account blocked for some...

    Bad block will ruin your budget.

    Bad casting, rusted head gasket surface, improper surface grind for a shim style gasket, cracked block or any number of things can burn your rebuild. My PO installed a quality block from a known re-manufacturer. The head surface leaked coolant into the oil and wiped my lifters. I had space...

    4L80E Information Thread

    The A/C pump will work. You'll still need a test manifold. You can't beat this price for the standard test unit: His price is $25 less than Jeg's sale price? They have it for $280.00. Sum is $283.99. $370 to $407 everywhere else. The Manufacturer Sonnax Industries has them on Back-order...
