What’s involved in swapping these transmissions? I want the extra gear.
I’m at 4.10’s right now?
>> I'm going to copy & paste this to the thread I just started to keep info together about these transmissions.... think your right about getting all those gears to engage at the right time.....Adaptors exist for the 6-speed. The controller gets interesting. Those really should be tied into the engine controller so the engine power can be properly cut during shifts.
The 10 speed, are you kidding? That has only been in the real world for a few months. Nobody is going to have ANYTHING for that right now. But stuff will come. Being co-developed with GM there will soon be stuff for that transmission. Few things in a year, maybe something usable in 2 or 3 years. Even then you will still want to use it with a proper engine controller as any of these new transmissions are no longer a stand alone affair of a few years ago.
IF you have been in any of these modern transmissions you will notice that the clutch packs are getting tiny. This is for fuel economy. When the clutch isn't engaged, the less clutch in the pack the less drag and better mileage. But these new transmissions hold big power and last forever compared to the dinosaurs of the past. This is done with careful powertrain management. The shifts come quick, which would normally be a swift kick in the pants shift. But with the engine torque killed right at the shift, the kick of the shift replaces the engine torque and it is programmed to happen seamlessly. So you feel a nice smooth shift with a steady torque feel all while the transmission makes a quick shift so the tiny clutch pack doesn't take a beating.
So if your idea of sticking one of these new 6,8,or 10 speed transmissions on the back of an old iron V8 and running a crude EFI or even a carb and expecting great results, you will be so sorely disappointed. Not only will the shifts be horrible but the transmission will be short lived trying to deal with sustained torque during the shift. It may run for a while, but it won't be a long lived nor a happy life.
