Hello, I stumbled across your thread here and have spent the last hour reading 95% of it. I must say. Excellent work! I followed you through the entire paddle shifter install and design, understanding it almost entirely. I HAD to register just to show my appreciation for this.
I have a 91 2wd Pickup that I have swapped an 06 Tundra 4.7 I-force with the A340E (not 100% on the E) as well as an 00 Tundra 4x4 with the 4.7 and A340F. I have yet to fire up the 91 as I still need to complete 60% of the build (Desert prerunner) My understanding is that these are different variations of the same trans. - Are they similar to the transmission in your Runner? - Can this be done as easily (for lack of a better term) on the later model trucks?
