7at -> 6mt

louiey370z · 04-05-2017, 05:38 PM

So I'm looking to have a ship install a manual tranny and take out my automatic transmission (it's close to failure). Was wondering exactly how expensive labor would be to get that done? This includes all necessary items needed as well

That's going to be a loo-loo.
In the (good) old days, you pretty much just cut a hole in the hump for the shifter.
Nowadays, everything is electronically connected. I don't even know if the computer has the software for both transmissions.
Keep us up to date on what you learn.

Will definitely let u know. Talked to one of my guys and he said that there are too many electronics for this vehicle and isn't suggested so I wanna find out more about that

It'll probably cost far more than replacing the failing automatic or trading the car on a 6mt Z.

As mentioned above, it's not an easy or cost-effective swap. I'd either buy a rebuilt AT or sell the car and get one with an MT.

Have Level 10 build your 7AT

it's not as expensive / pricey as people think it is. PM sent.

I've often wondered - can you shed some light on what is actually needed?

all the mechanical components, the OE Shift boot / trim. from what I've seen and have been able to research a re-flash is recommended to the M/T ROM for both the ECM & BCM. Also the TCM should be removed, This is what we have had to do on the Z33's and V35's i don't think it'll be too much different for the Z34 except for the rev-match feature. I think you'll be stuck like a base model without it but otherwise i haven't seen any major electrical differences. so my only theory I'm waiting to confirm is if a simple re-flash will fix it or if there will be more wiring involved.

Thanks! Hope you can report back after you've helped someone through a successful swap. I am certain the info would be invaluable in this community. This platform is still gaining better and less expensive turbo/SC options these days and I think the shortcomings and cost of making power with the 7AT is turning people off.... It could be cheaper just to switch to MT than build the AT!

Don't forget the Diff as your gears will be 10% taller & lag a little more if you swap from AT to MT.

Not really that much more expensive.

A fully rebuilt 7AT is slightly more expensive compared to a new clutch, flywheel, pressure plate, short shifter, and a HD CSC for a 700 HP rating combination. So in reality its maybe a thousand more. If you can do the work yourself, its almost the same costs for either MT or AT transmission beef up.

This is just something to ponder before giving up on the AT.

Pmd back. Thx

Selling the car would be the best option if you want less downtime.

Chuck33079 · 04-05-2017, 08:33 PM

What are you doing to this car? You're on motor #2, right? And now the 7at is dying? These cars are really solid, especially NA. Did you get a lemon, or are you beating this thing to death?
