Post subject: T5 Swap Help (Tue Aug 08, 2017 7:31 pm) Reply with quote

Hello everybody. I am sure this has been covered before, but I have a 63 D100 Panel with a 225 and an A435 4-speed. I would like to swap over to a T5 and was wondering if anybody has a solid, complete parts list/instructions (fyi the FAQ regarding the T5 is not working). Any help is appreciated.

Before doing a T-5 swap I would suggest you investigate the NP445 (NP4530) which is a fully synchronized, closer ratio transmission that should bolt directly in place of the NP435. With that transmission you could use a more conservative rear axle ratio like 3.55 or 3.23 and be able to use 3rd gear when climbing hills. The ratios are 4.56, 2.28, 1.31, 1:1. You'd have a usable 1st gear and much closer 2-3-4 to better keep the 225 in it's happy place. You can identify this trans by the New Process tag which gives the Model as 4530 and Ratio as 456.
