I did my manual trans swap on my 2008 G8 about six years ago. I was lucky enough to buy all the original GM GXP parts, including the harness, trans, drive shaft, shifter, everything, straight from GM. I was told at the time I got the last GXP manual harness in the USA. Got a manual diff from a GXP. I eventually fell in love with Corvette C7s and ended up selling the G8 to my best buddy from high school. In hindsight, I would not do the trans swap because it turned into a hardcore muscle car and became too much effort to drive with a lady. I had previously done the cam, headers, tune, and with the manual trans it was just a handful and relegated the G8 to just a badass, rough driving car that a typical woman would not understand or want. But I was also 55, which is a whole lot different from a 25 year old doing it. Hell yes I would love it if I were that age again. I should have just done a diff swap and a high stall converter and kept it an auto. Would have been a much better daily driver. Live and learn. But C7s (manual) are awesome cars and far, far, superior to the G8. The cost of the trans swap was close to $9,000 in total. New Tremec 6060 for the GXP was almost $4,000 by itself. I still have my complete parts list with GM part numbers, cost, etc. I also have the build notes from my engine build. Happy to share if you hit me up.

Amen !

[@VertigoGTI]

Picking up a G8 GT this week and my only gripe is the transmission. I’m having a shop go over it while I’m away for work… considering having them swap in a Tremec. Glad to see a newer video talking about the subject

[@danielp6629]

I just literally scored and entire GXP drivetrain (Minus the diff ). Interior pieces , harness all of it. All I need is to pick up a new clutch and flywheel and send off the BCM. I'm stoked. Nice video man 👍🏼

lets go finally someone not charging for the sauce

[@fabianchavez7052]

So i got a g35 coupe 6spd that i totaled and i got a cd001 trans in it and i was wondering if it will fit? I do know i need a clutch plate/adapter between the engine and the trans to be able to work, hope you can help me out a bit more if you got any info plz!!

[@ahmedadel4444]

good day my dear nice swap, what about a transmission crossmember for your tr6060

[@blaadimirr]

Where can I order the commodore harness so everything can work like oem

[@bobbyslaughter2946]

I thought the 4 gen camaro transmission could bolt right up to g8 from what I heard ??

[@buzzdownandrewww5267]

Did you connect the wire of the pedal ?if you did where did u connect do I have to connect it ?please let me know I’m doing mine rn

[@bsmothers1985]

Just wondering. That peace u gad to get from the comador for the plate that holds the manual. Could that be made? Just wondering

[@doomedgarage7580]

Oh yeah definitely

[@1125shifty]

I swapped mine. I used a Camaro tr6060 and I've had to pull the trans out twice now. Once cause of engine issue and now for a slave cylinder issue. But am I just not smart or is yours the same, the tranny hits the transmission tunnel in the car and is an absolute nightmare to get out. Shouldn't source a gxp bell housing or what's the solution

[@doomedgarage7580]

Message me on instagram

[@josephhansen4354]

Can the trans be swapped with the motor in? I was told it had to be pulled because it was to tight

[@doomedgarage7580]

I dont know who said it was too tight, but this is by far the easiest car ive ever worked on. Yeah you can do it with engine in.

[@Geni3420]

How much did the swap cost you all together?

[@coldblooded1210]

how did you get the tcs to work ? when I press the tcs button it shows up in the gauge cluster as "esc off" but it doesn't do anything. can you shed some light on this, thanks

[@doomedgarage7580]

My Tcs has never worked anyway, so i didnt worry about it. Its always said ESC off

[@coldblooded1210]

@@doomedgarage7580 am sorry. I meant my tcs is working but I am not able to switch it off , when I press the button to switch it off it shows up as switched off but actually it still switched on

[@makaylamantia9582]

Would the process be the same if my g8 was a v6 ??

[@doomedgarage7580]

Im not sure, I would think not

[@bgy1591]

Just get a gt

[@michaelpayne5925]

Where are reliable sources to order everything ? i have my auto trans out now i would much rather go aheasd and swap it.

[@doomedgarage7580]

Id try some Australian ebay or just look up commodore ve stuff. Or look up gxp stuff as well.
