Yeti's 1990 454SS

Ok…. Now I’m on the quest for a 4L80e core. Seems like most transmission shops want the core and i only have the crappy turbo 400, so I gotta find one.

I did call Monster Transmission. Same story. Core or they charge $900 for one. They offer a complete swap package for $6800. I’m sure it’s nice, but I’d be at $10k for just a transmission installed with new driveline. Doesn’t make sense. If i source it locally it’ll be half that.

Heck for $15,500 i could just buy a brand new GM LS3 with 4L60. So it really doesn’t make sense to buy their setup.

And still waiting for QA1 to send the front suspension. Once that’s here it’ll go in the shop for the complete suspension swap out. I’ll have everything that’s rubber under the truck replaced while it’s tore apart.

Budnik estimates the new wheels will be here end of March.

Try any local junkyards for a core, a blown 4l80 should be cheap I'd think.

Your approach on the trans front seems logical and I completely agree at passing on the Monster Transmission route at $6800. That's crazy talk. Surely sourcing a core 4L80e should be doable whilst perusing FB marketplace or something. Might even be worth buying a junk truck for cheap if it's got a 4L80e in it and then junk or sell the truck back minus the trans. Just spit balling ideas out there that I'm sure you've already thought about.

I haz no FB marketplace. Nor FB lol.

I’d rather buy a core somewhere than an entire truck. My parts mining days are long gone. Lol

@Rocket Man uses performabuilt- they do show price on website for 4l80 their "cheapest" one i think is still 750hp rated and $4k, he can comment on service

i used rossler for my initial build that transmission was about $6k rated for $1k+
i think they also have a sub $3k build

ATF speed is down in Davie, hell their stage 1 build 500hp rated is like $2500 bux no core

Stage 1 4L80E Transmission

this is who has mine atm. was very happy with rossler but the shipping each way sucked ,+$700 to any services i needed for the trip

jakes performance is probably #1 in the 4l80 game i would have used him but couldnt get ahold of the guy when i was ready to buy. but if youre not looking for high hp build probably not needed

these are just trans only, youll need a converter and control for full auto. the th400 uses a cable (or vacuum?) but i cant imagine the swap involves much to control the 4l80


6800 seems insane...and i would definitely not use monster transmissions ...horror stories

Looking through some listings in my area. I came across one for $650. Not sure how much it would be to ship to you but I’m willing to grab it for you and send her down if you have any interest and you can just send me funds for trans and shipping once we know the total.

EDIT: and just came across a second one for $750 in my area. Could possibly negotiate down for either of them. the $750 trans was just listed 6 hours ago. The $650 trans was listed “over a week ago”. If it’s still available the guy is probably open to offers. Or it’s sold and the guy forgot to delete the listing

Hmm. Good info. That’s right up the road from me. I’ll give them a shout.

And yes, the 4L80 will need a stand alone computer to control it. But it’s ready for an LS swap should I decide to do it later. I think the only thing that would convince me 100% is finding a smoking deal on a new LSX. I just feel like it’s absurd to take a 454 out of a 454SS to put an LS3 in it. Gotta stick with the displacement.

I am not pushing high HP. Just stock motor for now. And if i swap, the engine will be stock as well. I don’t need 700HP+ in an OBS like that. I have my other car if i want speed
