what kind of performance would i see from this shift kit ....and on that list it doesn't list the 3.5L engine....so will it work with it? And on install how much would most places charge.

 

the shift kit will better our shifts, smother and shorter. it isnt the engine that matters with the shift kit but the trans. you should have the 4T65e transmission.
you wouldnt really have to get it installed by pros unless your not mechanically inclined. it is a hour and half two hour job. so whatever their labor rate is per hour.

 

What about the intense shift kit is it any good? http://www.intense-racing.com/Mercha...ategory_Code=T
or should i just spend 30 dollars and get it from zz performance ...why is this one so much cheaper than the others

 

Photobucket or a similar site is THE easiest way to post pics here, and Google's advanced search is the best way to search the forum. Things just don't work right since the big crash last summer. MAYBE someday!

 

ttt im in the same boat as the thread starter
