Trans Code 71

Post by Action » Mon Oct 18, 2021 10:21 am

Has anyone had a 71 before with the 4l80e ? I tried a different speed sensor. Still have code. Looking at the trand TM, it should be easy to figure out with an OTC 3646 Tech 2 Deluxe Kit. the only kit I found for sale is almost $4,700 !
I installed some armor and frame rail clamps, then got code. Everything works fine, just to overdrive. I am pretty sure my engine is running more than 50 rpm. I can't find any loose wiring.
