Correction, a 4l80 flex plate, 4l60e plate lines right up to torque converter, you wouldn't even have to mess with the bolt holes. Some 6.0 have 4l60 flex plate. So you gotta get 4l80e flex plate bolt right up
With my first torque converter I used the cupped plate, with a different converter I had to use the flat plate with the spacer between the plate and the converter. You need to stick the converter to the plate when it is bolted to the engine. If the converter hits the crankshaft before the plate it will knock out the thrust bearing
From what ive seen get a flex plate for a 4080 off a 2001 to 2006 chevy 2500 heavy duty They bolt right up to a turbo 350 their are 2 sets of Holes pre drilled on that plate they line up perfect no need to wobble holes . I think your flex plate came off a earlier 6.0 like from the 90s those dont have the extra holes .
We have to fix a truck for work that originally came with a 6L90e it has a 6.0 l96 and it's missing the tranmission and the starter, we're planning to install a TH400/TH350. Will the original starter (l96) work with any of those two transmissions?
I am currently using a stock starter. It chirps just a little due to me not shimming it when I put it on and I ordered one for $50 on eBay so that could be why too. Local parts stores sells shims
@OMRY1561 - 4 min ago Hi nice video Great information I have 1967 cadillc th400 and 429 engine Do I need any adapter if i install 350 It1 gen2 1996 to the th400 thank you
There's no definitive answer for this different engines different transmission short crank wont crank different adapter case you just got to put it together and hope it works right you should have a little bit of play about one-eighth after everything put together there is no standard or offended answer for these you basically just got to figure it out and hope you don't mess something up
@@hesstons I made it a 350 transmission to a LS 5.3 l generation 3 engine and the transmission will not go into gear and when I disconnect the transmission lines it is not pumping no fluid I take the transmission back apart and there's no damage to the splines no damage to the tangs for the pomp and no damage to the torque converter and it look like they're torque converter was pushed all the way back and I had a eighth of play for the thrust my question is can you spend a torque converter by hand on the transmission hard enough to see if you can get it to pump because the only thing I can think of is that I pulled a torque converter completely off the pump and it didn't damage anything and it just sat there and spend or somehow someway the inside of the new pump for the transmission is broke the transmission has already been rebuilding it is completely new and the engine is brand-new ordered from summit I use the same kit that you highlighted in your video I've done everything the way it was supposed to be done I have 1/8 of play I modified everything to where I made sure I had the right amount of play and yet still I'm getting no fluid to pump and it won't go into gear and everytime I take it back to the part there's no damage to anything whatsoever is it possible I broke a brand new transmission pump on the inside and if so why is there no signs of outside damage
@thehatefull1761 that’s crazy actually. I have only ever broke one pump and my dad took care of it so I’m not even sure how to answer if it would look fine on the outside or not. It is always a possibility. After I did one I also triple check to make sure tc is in all the way. I’m not sure if you could spin it fast enough by hand. Did it spin freely when you bolted the transmission on the motor?
@@hesstons yes I mean it had some resistance from the weight of everything but yes it's spun around freely like it normally would I've probably done 10 transmission jobs in my life and everything seemed to be normal but for whatever reason it's not working the only thing I can think of is somehow someway I busted the transmission pump on the inside of it without causing any external damage that was visible

Hell yeah looks good brother and I'm all about saving money

I have only used the spacer flex plate and have never had a problem. Good to keep in mind though thank you 🤙🏼
@@hesstons different converters set up differently. My next one I'll order for an LS with the longer snout
Going to do this to my 70 Monte Carlo
Using one bolt to check if your holes are big enough made me laff and you know why ..haha
Haha I do indeed know what you are referring to 😅
THANK YOU SO MUCH. LS UPGRADE.
If you buy the right flexplate you don't have to alter the flywheel because it is VERY IMPORTANT TO HAVE THAT THING STRAIGHT & EVEN
This probably isn’t the channel for you🤣 we junkyard everything and haul ass around here

99 and 2000 had different cranks in the 6.0 which is where the spacer comes in. 80E plate is hands down the easiest way I would agree.

Great info. Can u do want how to connect 700r4 to LS
Only thing different is the kick down cable. If the 700r4 cable isn’t set right it will burn up the trans.
Yes I have heard. That

What was your clearance from flexplate to pads on converter ?
1/8” roughly
@@hesstons damn mine about 1/8 but not quite, gonna have to take converter out and see if it’s seated correctly
If tc spins freely you should be good to bolt it up👍🏼
@@hesstons even if the spacing isn’t quite 1/8? For some reason I can’t even slide the tc forward towards flexplate.
