6L80/6L90 into 68 Camaro does go....
#201
Great work throughout the thread. Very informative.
We are building a 67 corvette convertible restomod with upgraded LSA 700hp/680tq on C6 suspension and aftermarket chassis. Winters quick change 3.45 rear end. 345/19 tires. We have the 6L90e that also came from an 09 Cad CTSV takeout; same as our engine. We are debating if we want to use the paired 6L90e or, go with the 4L85e. Several negatives to using the 6L90e. Tunnel mods, crossmember, exhaust, shifters, programming and tuning, high cost to upgrade to withstand hp/tq.
The 4L85e creates none of the above and half the cost to upgrade for hp/tq.
However, I remain willing to go through the pain if the reward can be justified in performance. Do you have any suggestions or comments for me based on our driveline combination listed above and your experience?
I also sent a PM to poorhousenext for his consultation specific to C2 corvette installs.
Thank you in advance.

Its really about whether you want a 6 speed auto or a 4 speed. Yes the A6 is more expensive, more difficult to fit, but it is an A6.
A6 are getting increasingly popular in swaps even with the additional fitting challenges and the cost.

Had a couple PM's regarding the trans pan extension to convert a shallow 6L80E pan to a 6L90E shallow pan. Thought I had already posted a shot but clearly not!
This shot shows the 5/16" fabbed to shape plate extension which is brazed on to the shallow pan from the shorter 6L80E trans and fills the void that shows up when a 6L80 pan is used on a 6L90.

Have you experienced any problems with fluid starvation under high pressure from using the modified shallow pan? We are working on a 67 corvette restomod with the LSA and 6L90e tranny. We are upgrading the tranny now and discussing the shallow pan vs. normal 6L90e. Please let me know how the shallow pan is holding up under high demand. Thank you for your excellent postings.

Great thread and attention to detail! I recently purchased a 6.2/6L80 out of a 2013 Camaro SS and plan on sticking it in a .....1968 C10.... I know that's blasphemy, but it should be a fun setup. The truck currently has a 383 with a Vortech supercharger (620HP) and a turbo 350. It is fun to drive but not great to cruise in because of the 4.11 gears. I'm hoping the 6.2 and the A6 will be both, especially with the TVS1900 Maggie I plan on putting on it. I do have a few questions about the 6L80. How hard is it change out the output shaft to a slip yoke? Who sells these parts? Do you know a remedy to the lack of a dipstick? Did Lokar make one? What did you end up doing for the TUTD feature? Thanks in advance. Here's a couple pics of the truck with it's current setup and with the forth coming powerplant.

There is another thread on the output shaft and slip yokes. Dipstick, still dont run one. There is a GM level check procedure which works well. Trucks generally do have a dipstick as I understand it. TUTD hardly ever use. Runs fine in auto mode when tuned right. TUTD buttons are on a remote control .
EDIT: Here's a link to the custom driveshaft I was talking about:

Great thread , I am traveling down the same road as I am changing my 4l80 to a 6l80.Did some searching and came up with the pan and filter #s for the g8 and the caddy . has anyone used the caddy pan? and is there much difference between the g8 pan ? I may just order both of them and compare.
caddy - pan 24248164
filter 24236933
g8 - pan 24239528
filter 24236932
Thanks , JOHN

As to the dipstick I am going to try the factory truck one. It is pretty cheap compared to the Lokar. If it does not work out I will use the Lokar unit for a plan "B". As to the TUTD I have currently just run the wire(purple) into the dash area from the transmission. This way if I decide to do something with it the wire will be there.

On checking it looks like the 24243414 is the same as 24248164 and is the Cadi CTS and Camaro pan. Which is deep. Maybe the original Cadi picture showing a shallow pan was misnamed.

the 164 pan is deep ,the 528 is the shallower angled one , takes off about an inch. JOHN

I have been following your thread and I recently installed one in my 1996 Impala SS. I originally had a T56 with my LY6 6.0 and I am using a 2007 Corvette program. I have been having some trouble getting it to shift out of gear. I am getting TCM codes U0100(lost comm w/ ecm & pcm), U121(lost comm w/ ABS module) and U140 (lost comm w/ body ctrl module). Since I don't have the BCM or ABS module, do I need to somehow terminate the Can Hi speed connection at the pin? I am pretty sure I am in limp mode. Any help would be appreciated.
Same code(s) we're getting with my L92/6L80 build in my 98 jeep TJ wrangler. I'd be very interested in your advice/contents of this email--I think it might help me.
Thanks!

rsz288: i sent you a pm already. any help you can give would be appreciated

im also dealing with this issue. this one is an ls3 erod crate engine (e67 ecm) and 6l80 transaxle. the only code i get is u0100. im able to read and write both the ecm and tcm, can scan both, but trans is in limp mode.

That is most likely your problem. The best thing to do and maybe not the cheapest is to upgrade the TCM in the 6L80 transmission to match your ECM. The other option is to get an ECM that matches the 2007 transmission TCM. I would get ahold of the people who sold you the crate engine and see what they can do or have to say.

my dilemma is knowing what to try. ive read at some point that gm changed the operating systems and old and new wont communicate. ive read 2009, others say 2010. after some more reading what id like to do is flash the ecm and tcm with a complete file from another vehicle. i have a stock file from a 2009 ctsv with 6.2 s/c and 6l90. its not a big deal to change the tuning values over to what i currently have so basicly id be doing an operating system swap. what i dont know is does the 09 ctsv fall under the early or later operating system, and if the gmpp ecm falls under the early or late operating system. the 09 ctsv is the earliest i can find an e67/t43 combo.
just thinking here, i guess this might be worth a shot. just when i started working with this shop they did an ls3 and 4l80e from a trail blazer ss (i had to come in to make that mess work). if i were to get that pcm and plug it in, would it in theory work?
#217
I am in the same boat as you are but I got lucky because my transmission is a 2010 year. For me that means I can probably run a 2010 Camaro E38 ECM.
In my research it seems that 2008 and 2009 are similiar. There were changes again in 2010. Also it is best to use the same year for the ECM and TCM. There are others on this forum who are better versed on the subject than I am. I think you are headed in the right direction. Just have to be careful that the service number on the ECM will take the flash with out it locking up.

You need to see what operating system is in the TCM. Then post the number and see if someone can lead you in the right direction in for a matching ECM.
By the way what year is the Trailblazer program out of? 2007?
