It was only chebbys (maybe fords also, I know little about them), that had two gear ratios. Dodge did use the NP445 in the mid 70's which is similar, but has a synchronized first gear with a relativity normal first gear. Dodge did use two versions of the NP 435, but they were a time issue, one up to about 1987, then another after. The difference is in the internal parts, most of which cannot be w=swapped from one to the other. Also dictates which PTO's can be used.W_A_Watson_II said:NP435 was offered in two 1st gear configurations, one Granny one not.
Any of the trannies without a granny gear, are hard to start out in second. granny gears can be skipped for most normal driving. One trip, and you will know what you have.stan2088 said:Would the identification tag have the info on which version the transmission may be, low granny gear or not.
