Any1 knows where I can buy a Electronic Shift Kit for my LS4 Monte Carlo? Heard B&M makes some not sure if it will work for my LS4 Monte Carlo? Has any1 used an electronic one b4 and does it work?

 

I've never heard of an electronic shift kit. Are you sure it's just not having the PCM re-tuned (as the trans has a lot of controls in the PCM)?

 

Not sure buddy? By re-tuning what do u need to do?

 

There are 2 ways to adjust shifting on electronically controlled transmissions:
-Mechanical shift kit (which changs out springs and spacers above the transmission pan)
-PCM/TCM retuning

Your transmission is a 4t65hd and there are many mechanical shift kits avaliable (plus diy options). These kits are relatively easy to install (not much more labor than a fluid/filter change). Some kits make the shifts harder than others. Most of the off the shelf options are mild-moderate increases in shift feel. However, only the shift firmness is adjusted with this modification.

Being an electronically controlled transmission, there are a lot of other transmission parameters that can be adjusted via pcm tuning. To some extent, shift firmness can be tweaked, but you can also change shift points torque converter lockup, etc along with engine parameters. Options this route include a pre-tuned pcm swap (ie buying a vendor's pre-set or semicustom tune) or buying a tuning package and making the changes yourself.
