Manumatic shifter addition to a base G6-V6

[mobilebyrd]

wondering if the manumatic shifter from a GT will fit a G6 V6 and function properly.

Any opinions?

I'm pretty sure that this has been discussed before, and the conclusion was that it wasn't possible.

I think that a coupe of things stood in the way, one is that the tranny doesn't have the programming for tapshift or whatever it is that they call it. The second was that the tranny doesn't have the hardware to allow you to just switch the shifter.

e2helper, can you shed some light on this one?

lol that is excatly what i thought when i first read it too.

The service department said they might be able to reprogram the computer but was not sure.

Hmm. You are correct that the PCM for V6 has different calibration than the one for GT. If you were to just put the GT calibration in the V6 then you would have transmission problems because axle ratio is different - I don't know how it would manifest itself though.

I know that both shifter and shift cable would have to change and the BCM would have to have a slight configuration change to enable "Tap Up/Down" mode. I forget if all the wiring is in harnesses, there are a few extra wires for this function.

But biggest problem as mentioned first is calibration in PCM to support function.

I can program the ECM to support it no problem, I'll just make you a custom cal. If the TUTD controls are simply 100% ECM based it wont be a problem I believe you can still option out a BCM after they have been programmed and locked so adding that and the appropriate wiring is all you'd have to do

[e2helper]

Yes that BCM change is a simple configuration option bit in one of the DIDs and not in one of the secured areas. If you didn't make that change then the PCM would set a fault code and likely drop out of Tap Up/Down mode because BCM provides an enable signal when shifter is in TU/TD gate (micro switch in shifter)

e2 helper what do you do man cuz you are a g6 genious.

[e2helper]

You should be able to guess

You should be able to guess

The cheif design for the g6. I knew it. You built her. lol. So you work in service. I told the dealer about the programing of the radio and gave himall the info. When I picked up my car he was like well the issue was in the programing. I was like WTF I told you that. Cool stuff. I will probably be sending you another pmone of these days. I seem to always break shit.

So, the general consensus is that it is possible ? Some wiring and computer programming needed along with actual shifter and possibly some linkage...correct?

[TLS2000]

I think the general consensus is that it may be possible, but not really worth the expense of doing it.

If you wanted the tap-shift, why didn't you get it?

One other thing, just a suggestion, but you know how your gear selector has P,R,N,D,3,2,1 on it right now? Manually selecting the gears that way does the same thing.

[jsholli]

Do any of the other auto models actually have a low gear selection? Mine only has a spot for 2nd/1st. That maybe a base model thing, though...

[bristol16]

are you saying that 1st and 2nd share a spot or you only have spots for 1st and 2nd but not 3rd? i have seen a lot of cars where 1st and 2nd share the same spot.

PRND3L on mine.

I think it's PRND321 on Malibus.
