    Yeah, there were a few wires I kept from the old engine harness. You need a set of wiring diagrams from your 94. There's a lot of work figuring out what you want/need to keep. Then you painstakingly...

    Thanks for your service Marine Raider1!

    If cost is an issue I'd rebuild the 5.3. That saves you a lot of headaches and a million little parts that end up nickel and dimeing you to death. Take the...

    Depends on your 4L60. My '92 was not computer controlled and had a vacuum hookup for kick down. I'm not sure how I would have got it running right, but I'm sure it's doable. 4L80 is a nice trans, but...

    First off, read my swap thread listed in my signature, very similar to yours.

    Second, your stock tranny has kickdown based of vacuum I believe? I could be wrong there, but there will be issues...

    You don't mention if you're putting in a Gen III or Gen IV motor. For Gen 4 you don't use a tac module, just the pedal. The pedal from a 2012 Yukon fits and works great, It's a lot easier than trying...

    Well it's been a couple of months... The truck is running outstanding. I switched mufflers to a different Dynomax VT; simply outstanding sound now. Very quiet until you get on it and then a very nice...

    The internal linkage was not hooked up. Why that was so, I don't know. I do know that Stricker Auto on Ebay sold me the trans and it was supposed to be out of a running vehicle. It could not have...

    I thought being somewhat slow off the line was probably torque management. I raised the torque limit in all the gears way up and disabled traction control. HOLY CRAP! It's fast off the line now. ...

    IT'S ALIVE!!!

    Turns out it was the internal shift linkage. Interesting, because the trans was supposed to have come from a running vehicle. Not possible. I'll get videos up, but here are my...

    True, but I'm checking oil off the ALDL link. Turns out that was an issue with HPTuners, as another scan tool sees the oil press and temp just fine. I'm getting Fuel level, oil press, etc in to the...

    Already fixed everything but the tranny not going into gear. As far as that goes, It's either an OS compatibility between the TCM and the ECM--most likely I think--or a VIN incompatibility--Less...

    I hate problems like this! Very tough.

    First, you need to try a known good scanner. If the EFI tuner was able to communicate I can't think of any reason your scanner wouldn't, unless it's broken....

  21. Calling anyone who has swapped a 2004+ engine into a 1998-2003 rig

    From 1998 till somewhere around 2004 GM fuel senders were 40 ohms empty and 250 ohms full. Then they reversed it to 40 ohms full - 250 ohms empty.

    I swapped a 2012 L94 6.2L into an older rig. The...
