Question about 1999 GMC Suburban
Help...94 Suburban 1500 auto 4x4, I am changing the gas engine to Diesel, My helpers are saying the transmission will not work Because it is computerized, What will cause it not to work? I think the kickdown might not because No cable from accellerator to Transmission....Any help Please.....
I'm pretty sure GM built your truck with the diesel engine as an option so there is a way to make this work. The trans shifts are based on a combination of ground speed and engine RPM so as long as the computer is able to get these signals your trans should work. I put an early 90's overdrive in a mid 80's truck and didn't plug the wiring in because the trans used a 4 wire plugin and my truck only had a 3 wire. It worked fine, even overdrive.
A little jury rigging and ingenuity should find a way to attach your current kickdown cable to the accellerator on the diesel pump. GM probably has a bracket to make it fit. Check with the parts guys at the counter. Hope this helps.
