Hello,
Tried searching, maybe I wasn't searching the right keywords but couldn't find anything.
Just swapped a 97 L31 vortec into an 87 s10 and mated it to a NV3500 5-speed trans. Currently runs off a 0411 pcm with an express can tune and everything is operating perfectly except I have no signal from the speed sensor to the pcm or the speedometer. After doing some searching it sounds like it's because it is tuned for an auto trans and unfortunately the express van never had a manual trans.
I emailed tech support asking about the segment swapper but I know there are a few people with this setup and was curious if anyone had an express van with a manual trans calibration already available? I checked the repository but did not find any, mostly just 4l80e swaps. My last resort is send it out to have it modified with efilive but thought I would ask here first.
Any help would be appreciated!
