Budget Turbo Yukon XL 4L80 Conversion: We Have Driveshafts! Torque Converter Spacing & Shop Talk

What happens here

The presenter explains the critical procedure of shimming torque converter bolts to ensure proper clearance. The rule is to have approximately 1/8 inch of 'pull-out' (or play) for the torque converter before tightening the bolts. This prevents the converter from damaging the transmission pump or being 'buried' too deep. Shims previously removed from an Escalade are used and hot-glued together in pairs to simplify installation and prevent them from falling. The presenter demonstrates pushing the converter back and forth to show the desired play.

Goal: Ensure proper spacing (1/8 inch pull-out) for torque converter bolts using shims.

Tools and materials

  • Hot Glue Gun — Gluing shims together (as demonstrated in previous project)
  • Metal Washers/Shims — Adjusting torque converter clearance
  • Torque Converter Bolts — Securing the torque converter to the flexplate

so it has movement you don't want to suck it the whole way to the flex plate because you can pull it away from the pump in here suck it and you don't want to be buried in the pump because then as things move you could shove the converter into the pump and junk that too so you have to have some room the way this weird pilot thing is um we're gonna have to have washers in here because it won't go the whole way into the flex plate so we just have to make sure there's an eighth inch of room like an eighth inch of pull out from the pump at least an eighth inch and then we should be okay because that's that's your margin of error to keep the flexion of everything from butting into the transmission and ruining it wait what the [ __ ] take it back out no oh no we just have to when we go to bolt it up we just have to slide um a washer or two into here to put the bolt in and tighten it yeah i was supposed to be so annoyed oh yeah no i'm not doing that no we're not we're not doing that again i'm not doing it again either good screw that hell no waiting to find some washers okay i found some washers they're actually the ones that use the shims from the escalade um we're gonna have to double them up because um as you can see the little pilot spacer we had to put in there it doesn't allow the converter to fully seat against the flex plate which really doesn't matter because we have to push it back out to have that eighth inch shim anyway so we double both of these up and it will push the converter out enough so that it's not butting against that uh that hub either sometimes getting these in like doubled like this was a pain in the butt so for the escalade i don't know why i didn't just weld them because i didn't feel like it i guess i hot glued them together and it worked just fine that's literally so funny that's literally what i did i hot glued these washers together for these it won't be too bad to feed them in stuck together like this but when the escalade has six
