Swapped to a 4L80E

[Turbo1dr]

I have one and it does not fit. If the floor wasn't there it would be fine. I emailed them and have not heard back yet. it says they respond in 48 hours. will see. I hate to spend more and have our fabricator make it work.

I made my stock crossmember work while I was waiting for mine to arrive. I still haven't installed it though. Thanks for the warning that it probably won't fit.

My last 4L80E was in my 8T6 t-Type/LS turbo build.
I used the column shifter, modified the x member. Some welding but fairly straightforward
deal. I may still have some pics.
And no, no tunnel mods for 4L. 6L is a different deal. I do suggest trimming the tunnel pinchweld.

How did you connect the rod off the column to the 4L80 so the reverse lights work and safety neutral switch etc..

It's listed in detail within this thread. Backtrack towards the beginning. Maybe post 60 or so.

We extended the stock linkage. Quickturbov6 did the work and does the mod for others.

We modded the stock xmember. But the hr-parts trans mount will likely work with the adapter plate flipped. (Which I plan to try)

I ended up using it. We slid it in there and twisted it into position with a pipe wrench. If it was straight on the left side, it would have fit better. Its not right at all. mount wasn't even close. We pulled down on the trans and the mount kind of fell in place but its not right. I was going to notch mount like Bob did on his. After all, that I looks like the exhaust is going to hit it. I just can't win. This is made a for an LS engine or v8 with dual exhaust

Bob on the shift cable bracket you have c-351 listed. Shiftworks shows a bunch of kits with same number. Do you have a specific part number? Thanks for all the posts you have put up here. Huge help.

Trans has been in for a while. Made some pretty good pulls with it but now I'm running out fuel. So there goes another $1000. I like how it shifts, we really haven't messed with it that much. Some hiccups at first but Bob and Eric both helped immensely with the set up and tune. We see how it runs in the spring when we install the twin Hellcat pumps. Thanks again Bob! First class as always

In round numbers, what has the swap cost you?

In round numbers, what has the swap cost you?

Adapter plate and longer dowels were $129
Trans was a steal from Ck $1699
Converter was $1100 from Dusty lock up converter
controller was I believe 650. I do have GnECU
Drive shaft was $595 I had him do the sonnax yolk and its chromoly 1350 joints
Cross member $239 . This thing fit like socks on a rooster. I should have just stock crossmember mod.
Linkage was around $120.
No speedo at this time. I was going to get the tail shaft housing from ebay for $500 so you can just use stock cable with an extension but I'm going to do the DIY dash next season.
Forgot about the trans cooler and lines. $400 I got the Derale with fan and evil energy line kit.
I need to figure out a drive shaft loop. A normal loop ends up at end of trans. Seen some modded ones on here. I will have our fab guy make something.

So just about $4300 and I don't have to worry about it. I real good 200 is 4k and converter is 1200.
I was really hoping for 600hp but by the looks of fuel being used its mid 700 and running out of fuel So next season twin hellcat pumps and maybe a little more boost.

That trans was a deal from CK back in 2015. He had three of them for $1699 shipped. Im sure today to build a trans comparable would probably be 4k

Don’t forget Tuner charged $5300 you still owe him!

Twin Hellcat pumps on Saturday is what you meant to say

I forget which one it was (I found it on Ebay) , I just used part of the kit. I only wanted the bracket that mounted to the trans, which all the C351 kits have I believe. (I think it was for an old Chevelle)
