Ask Away! with Jeff Smith: How to Make the Kickdown Work on a TH400 Transmission Swap
I have an ’85 C-10 pickup that we’ve installed a factory fuel-injected 5.3L truck engine. We bolted a TH400 transmission to the LS engine but I now realize that I don’t have any way to trigger the kickdown linkage on the TH400 trans. How do I do this so I don’t hurt the trans? R.G.
