Im getting to the point in my swap where im down to the small stuff, and as far as the speedo goes what is need to have it work properly, im going from the 700r4 to the 4l60e and if im not mistaken the 700r4 was mechanically controlled while the 4l60e is electronically controlled so what needs to be done to be able to use my exsisting speedo in my iroc??

also has anybody heard from Z28*****????? he has not gotten back to me in about a month

thanks

 

You need a drive box. Check Hawks site, they have one. There is also a cheaper version out there, I haven't kept track of it personally because I went with an aftermarket electronic speedometer.

 

alright thanks for the info i found the box online, and i wanted to keep my stock gauges but looks like it may be cheaper to go aftermarket thanks for the help!
