  1. Trailblazer to Envoy dash swap?

    Interior
    I was wanting to put an Envoy dash in my Trailblazer. Has anyone done this or know if it's even possible? I know the gauge cluster and dash controls would have to be swapped as well. Just wanted some input. Thanx guys.

  3. Front end conversion

    The 02-09 "How-To" and DIY Section
    Hi guys, I’m new here but I just picked up an envoy xuv. For some stupid reason I’ve always wanted one of these and I have a weird obsession with envoys in general, but the waterproof truck-bed style rear end with a retractable roof just blew my mind. I had to have one. But one problem; I don’t...
  4. TB trans interchanges

    Transmission Mods
    Hello All. I just joined a few weeks ago. My first TB has low mileage, is rust free (for NE Pa), and has - you guessed it, a dead 4L60E. No 3-4 gear. So some quick first questions about used transmissions: - what other year 4L60E's will bolt / connect up to my 2002? - is it a good choice to...

  7. interchangeable driveshafts?

    OEM Issues
    Hi guys, I'm new here. I recently acquired a 2006 Trailblazer LT that has been having driveshaft \ u-joint issues. The former owner replaced the chewed up old driveshaft with a $35 used rusty junkyard shaft and a new rear u-joint. It wasn't long before the new u-joint fell out. I made an offer...
  8. Unlocking Bose 6-Disc Changer for '02 TB

    Audio and Electronics
    So, I'm going to fully explain my situation to help alleviate some concerns. I successfully pulled the Bose speakers from an '03 Envoy at a salvage yard, and swapped them out with my stock sound system (mainly for an upgrade, as the rear stock speakers were blown.) They work great, but I...
  9. Engine swap questions???

    Engine Tunes/Mods
    Hello All, First time poster but I've been lurking for a while. I'm wanting to swap a 4200 into an 87 Jeep Wrangler, my plans are to convert the jeep to 2wd, lower it a little, install the 4200 and turbo it with an auto trans. My questions are which year engine and harness to use. I want to use...
  10. [SOLVED] 2003 Trailblazer EXT L6 4x4 Transmission Madness

    General
    I am trying to determine if a problem a friend is having is the PCM/ECM. His 2003 Trailblazer dumped its tranny and so he grabbed one off of a GMC Envoy(as he tells it). He had driven the Envoy to be sure the tranny was good, no problems. After his 'tech' swapped the transmissions, and...
  11. Swapping between Envoys

    General
    Old envoy rusted out at rear control arm mount on frame, bought new (used) envoy. Old one was 2002, 330k kms, new one is 2003, 152k kms. Both are SLE 4wd models, but I suspect the newer one is a bit more base model. My question is what (and how easy) can stuff swap between? I want to swap from...

  13. larger side mirrors?

    Exterior
    Has anyone else notice our side mirrors are a little on the small side? I was wondering if anyone has any ideas on some larger mirrors, i.e, would suburban/yukon mirrors fit? With my lifted TB I'd like to have a bigger picture of what's behind me as I drive. Thanks for the input
  14. Engine swap comes to a halt..hoisting bracket??

    OEM Issues
    So after the longest wrenching hours of my life, I'm almost ready to drop the engine and transmission in as an assembly. What are my options for the secondary hoisting point? Thanks for the help guys!
