@mountainsgarage You fo realize that the pilot on the PTC converter unscrewed off of the torque converter? Before you welded in the center there is 2 holes for a spanner wrench to unscrew. Wouldn't it be better to remove and weld off of the converter instead of welding to the converter? That way if you ever decide to put trans and converter on another engine you can just unscrew and machine down?
Thank you! Exactly what I noticed with that slide in adapter. I’m running the fancy TCI flat flex plate with the raised pads. Converter would not pull up to them. Bottoming out in the adapter. Turbo car, has all the trans and thrust mods, but still beating on the thrust!
@@justinlemons3645 I can now pull the converter up to the flexplate. Couldn’t with the slide in adapter. Can’t speak to the thrust. Not enough runs on the car.
At 1st this really didnt make sense to me. By the end I figured out, you are letting the flex plate hold the converter from the pads and not the snout bottoming out and making it solid.
Great video! Really enjoy all the th400 videos. I actually ran into this problem this last weekend. Wished I’d thought of this solution. I got rid of your favourite adapter spacer and added the factory one on the outside. Lol. Anyway, I have 0.200” between the flexplate and the torque converter pads. Close enough to 3/16” or should I shim it a bit with washers?
Hey Shawn, I love this, I have always thought those dam spacers were garbage.. Any chance you would be interested in cutting a few of these for me and letting me purchase them from you?
@@mountainsgarage yes you definitely should and I would definitely like to purchase some from you I wasn't kidding LOL I've actually got three different converters that I'm going to try in my combination turbo LS with that turbo 400 I was telling you it's time to build but it would be nice to have one on the end of each converter so when I switch them I don't have to weld another one on every converter but I would be glad to pay you and shipping whatever it takes you clearly know what you're doing and I trust you if it's something you would be interested in please let me know I would love to purchase some if I need to buy more than a couple so be it
@@mountainsgarage Hey shawn! I apologize for bothering you again but I have a question on a subject that seems to get a ton of different opinions or answers what have you when it is asked but again I value your information I would like to know where is your ideal location for a transmission temperature sensor I have always just installed them in the pan because in my crazy brain that is where the filter is taking the fluid from and feeding it to the transmission Maybe I'm Wrong but I'm curious where you suggest I put it I was getting ready to drill and tap My Pan and figured now would be a good time to ask before I did thank you in advance sir I look forward to hearing from you
Hi Shawn. I have a vega in which I plan to update with an LS since the engine needs to be redone and know nothing about LS so I am learning a lot through your videos. At first I thought you were describing a trans thrust washer versus the crank. Apparently this is an aside I will need to address also. Thank you for the info. Forgive my stupidity here, but as in Algebra in HS, I'm not following here. If the crank is attached to the flywheel and the flywheel is bolted to the converter, with or without your update, the crank should still get pressure, yes? So your mod is just to center the converter on the flywheel/crank, right? With or without your mod, and if the converter was spaced out a1/8th", the center of the converter won't touch the crank flange, right? I feel I'm missing something important here.
The flexplate needs room to do its job and the converter should have room to slide in the crank. If the converter can’t move then its going to transfer force to the crankshaft.
@@mountainsgarageThanks for answering Shawn. Is this because the converter hits the driveshaft instead of sliding in the hole? I know, like in algebra, the answer must be so obvious yet I can't see it.
So I'm going to have to buy a converter for my LH6 5.3 and th400 can I buy a converter thats made specifically for the ls and th400 or will I have to do this?
Whatever you get it only takes a minute to check. If it’s already attached to the converter wipe some grease in the end of the crank so when you hold the converter on the back of the engine you can see how much space is left.
Hi I really like your videos, great info on the th400 transmissions, I understand what you doing with this mod letting the flexplate flex as It should and unloading the crankshaft, but if you run some sort of billet aluminium "flexplate" ( like me on my 2j) or this mod don't solve the issue for your buddy, an other way is to mount a roler bearing on the crankshaft like these guys m.ua-cam.com/video/lalaTWJ4mDo/v-deo.html about 4:30 in the video Don't know if you have seen this before or what you're opinion on this solution is? It's a lot more complicated for once...
Fantastic video here. I'm 65, old mechanic and never knew the th400 could be so much Fun.!
Thanks for watching!

Yes that would have been a better option but it would not move. :(

Did this fix ur problem? I'm having the same problem u are

Nice work. Thats way better than the spacer.
You should make and sell those spacers.
Brilliant!

Yes, as it should. When it hits solid bad things happen!
nice video thanks
Hey Shawn, if you decide to make any of these spacers please let me know. PayPal ready!
I think I should make a few.

I would shim, if you study the pump gears to hub relationship not much room for error.
Just machined out of Mild steel? Going to have a friend make one up for me.
Yes
Thanks U!
Hell of a idea got to work better
Have you ever drilled out oil holes in cam bearings for better circulation
No but have read about it!
Hey Shawn, I love this, I have always thought those dam spacers were garbage.. Any chance you would be interested in cutting a few of these for me and letting me purchase them from you?
I should make some for sure!
@@mountainsgarage yes you definitely should and I would definitely like to purchase some from you I wasn't kidding LOL I've actually got three different converters that I'm going to try in my combination turbo LS with that turbo 400 I was telling you it's time to build but it would be nice to have one on the end of each converter so when I switch them I don't have to weld another one on every converter but I would be glad to pay you and shipping whatever it takes you clearly know what you're doing and I trust you if it's something you would be interested in please let me know I would love to purchase some if I need to buy more than a couple so be it

I used a short crank 4l80e flex plate

Hey Shawn love the videos. I’m building a th400 soon and could use your help. What’s the best way to contact you? I don’t have Facebook, thanks
smountain1@roadrunner.com will work
i cant use a allison waffle clutch disc on direc, foward drum, for street and drag
on my th400 transbrake?
Yes you can.
@@mountainsgarage thanks
Gotta keep that bench from rusting 😉🤣
Could you not lathe down the pilot adapter so that it does not bottom out on crank?
No it would cut it in half, it’s stepped down.
How do I get in touch with you to purchase spacer?
How did it work out on your buddies truck?
Good, a few years ago now.
Where you located think you can help me out with this ls to PowerGlide
Standish Maine. You?
@@mountainsgarage Redford Michigan you 2 hours away definitely will make that trip
Does a 2000 lq4 6.0 need any mods to use a th400 ? It bolted right up no adapters Am i going to have problems i dont know about yet ??
It should be OK but on assembly never hurts to check. If it’s a stock converter probably fine, aftermarket maybe.
Howdy.....anyone find a place to buy these weld on spacers yet?
Thanks!
I have some if you need one.
@@mountainsgarage awesome....what is the best way to order? Thanks!
So I'm going to have to buy a converter for my LH6 5.3 and th400 can I buy a converter thats made specifically for the ls and th400 or will I have to do this?
that would rely on the tq converter maker , some send that goofy adapter or one that is threaded onto the converter
Whatever you get it only takes a minute to check. If it’s already attached to the converter wipe some grease in the end of the crank so when you hold the converter on the back of the engine you can see how much space is left.
Can I order that extension?
I have a bunch of them.
@@mountainsgarage how do I order?
👍👍
