Transmission Question

From : dmso

Q: i have a 1996 1500 ram 4x2 5.2 engine 4 speed auto extended cab and 8 foot bed. it has 280k miles on it and the transmission has about 100k since the last rebuild. at the moment i am having no problems with the transmission however i know it will not last forever. i was wondering if anyone has had any experience with swapping the auto trans with a manual. i did it with a few cars back in the late 60s - early 70s. however i realize things are much different with todays trucks sensors computers etc. i am just wondering if it is ; 1. possible 2. worth the effort and cost. the bottom line being i plan to hang onto this truck from as long as possible thanks david .
