How much spline engagement do I need?
I'm working on mating a 6L90 to a np205. I have the short 29 spline transfer case input, and the shortest 4wd 6L90 output shaft. After I get done cutting everything to length, I'm probably going to have about 1.5" to 1.75" of engagement of the transmission into the transfer case. I haven't found anything out there whether this will be enough.
The truck won't see a lot of abuse and it won't be a high hp/tq build or anything, so I'm thinking it will be alright.
What do you guys think?
