hey guys
so i have a 89 yj with a chevy 350 with mild work done to it soon to bb made a 388 bolted to a turbo400. I had a np241c t-case untill i broke the tail housing and the adapter plate to the tranny i think the guy i got it from didn't install it right. But ive been thinking about upgrading to a np205.. at the moment im running 35s thinking about going 38s soon.. ill doing doing alot of mudding and some pre running since i love to go fast and some rock crawling.. so what do you guys think would be the best for what im trying to do??? any ideas or opinions?? thanks guys

Well the 205 is pretty bomb proof, the down side to them is that low range is only 2:1. Not much of a crawl ratio there. It will be good in the mud and do just fine on dirt trails but not a great setup for rocks. The auto trans will help some in that aspect though. You could go with an sm465 trans instead, theyre cheap, plentiful, easy to work on (compared to an automatic) hard to break, and have a 6.5:1 first gear which would get your crawl ratio to roughly 60:1 with 4.56 gears (you didn't say what gears you actually run). Either way good luck.
