im thinking about pulling the A518 auto trans out and putting a gear jammer in. what would be the best one to put in there? i have a 93 5.9 intercooled in my 97 ford f250 HD any insight would be great i gust cant make up my mind thanks Mike

 

NV4500 out of a 94-00 Dodge, good clutch for it and your golden!

 

A getrag with the proper supporting mods (overfilling it, not lugging it) would be easy and you dont have that horrible gap between 2nd and 3rd.
