Build a 1200+HP rated 4L80E for under $1200 !!

So this is how I built my 4L80E to handle 1200 hp for under $1200.

Parts used for the upgrade:

A lower cost trans rebuild kit with kolene clutches without extras but cheaper-

A better 4l80e Automatic Transmission Rebuild Kit with Kolene clutches

A better input shaft than what I used for the same price:

Not part of the transmission but I bought a stall converter while I was at it. Here is one rated for 800hp but more flywheel bolt patterns

A versatile 800hp rated Stall Converter:

The Milwaukee Impact I used which is amazing!

69 chevelles/Camaros are the best looking GM cars. I had a friend and he had a 1969 SS396 Chevelle and It has been my dream car since I was 12 years old. I like the Chevelle a little better than the Camaro because they have a full frame that can be reinforced.
Thanks!

Dont forget a good cooler and proper trans tune

Thank you for a nice video. I picked up all the parts to try and build my junkyard 4l80.

Im mixing up the Transgo and sonnax shift kits in my a604 those expander wires on the input shaft and the kevlar seals on the input shaft is a charm

New subscriber!! I just went through your channel and I love all the different topics. I’ll be binge watching tonight. And of course with some THUMBS UP!!!🔥🔥🔥🔥🔥

Wouldn't mind seeing the whole rebuild if you take it apart again. Or a 4wd to 2wd conversion.

Great video man just subscribed I’m the 999th hope u get to 1k!

Looks like you bought one of those ebay transmission mounts that you have to grind one of the legs down just so it will fit. I bought one too thinking it would work right out of the box.

[MechanicConnection]

Can you add a link to the holder for the transmission? The ones I can find say will not fit 4L80E or GM powerglide without modifications.

[PTTrue-murq]

How much horse power can a stock 4l80e hold?

[bryanleal]

Will you need a new tune? Or will the regular TCM base tune work just fine?

[BHZ]

Awww shit excuse my language but I think your my transmission sensei

[willwhite]

Will this fit just a 4L80 to ? & not the e

[ericperry]

What do you recommend for a 1500hp

1991 4l80e

[johnsimmons]

Billet main shaft and transbrake future plans?

[HandMadeWrath]

This is cool… now how do i make it a 6 speed?

[Ginx-pesi]

It can handle 1200 hp but for how long? Thats the real question

[williamdillingham]

The paint makes the transmission run hot
That's why the case is made of cast aluminum just like air cooled engines
