Does anyone know if there is a rpo code to identify the t case? Or is it easier to just look at the case itself. Because i have electronic t case but not sure which one i have and want to put a stick one in. Which correct me if im wrong a np241. Sorry for all the questions, but whats the np243?
IIRC the 246 wasn't an option until 98, so if it's a pre 98 the only electric case option was a 243.
Most simply a 243 has 2hi, 4hi and 4lo whereas the 246 has a fourth function, auto4 in addition the other three.
