Hammer on it, you know drive it like a 16 year old going going to get his first piece of.

 

to answer your last question yes they are a great engine. just make sure you monitor your fuel pressure to the injection pump. i have a k and n intake on my truck and 5 inch exhaust and a small bully dog programmer and i have 111k on my truck and the tranny is fine knock on wood. hammer on it means beating on it. like not boosted launches and neutral slams, etc. etc. get what i mean?

 

Yeah i understand. How long do there trannys last for? is there any economical way to improve them a bit, so they wont mess up? remmeber im just a daily driver not going to be pulling anything.

 

not really if you dont go over like 70 horsepower over stock you should be ok. i have a 65 horse chip on mine and it doesnt slip even towing so just drive with some sense

 

So a smarty jr would work just fine? i want it mostly for fuel savings

 

The engines will last half a million easy but the trans is another story, not one of dodges better designs. If your buying a used truck then it all depends on how the truck has been used as to how long the trans will last ofter you get it. Just don't hot rod it every day and it will last longer.
