If not, a good shift kit or just a pro built valve body, some hard parts you can install, and maybe a billet input, and you can have a sweet trans to do some dumb stuff with. I have one in all my conversions I own currently. You can get a compushift mini to control the over drive and lock up and they are relatively cheap too. It's hard to go fast in a 5 speed and in stop in go traffic, that garbage gets old. That's coming from a gear jammer. Haha I had a NV4500 in my 72 and pulled it because I wanted to go fast too.

That means your engine is more than likely a 160. If it's an 94 or early 95 it will have a WH1C on it. I can tell you some things to check on it and or do to it when you get there.
I know that the converter has been worked, so that is a very good thing. I guess I will start to put together a parts list for the this trans and I plan on now using it in this swap.

Thanks for all the info on the trans, I appreciate it!!!

I was guessing that this engine was a 160 hp. Which is not a bad thing. I use to know a Cummins company field rep in Ohio and he use to tell me that they had these engines in marine applications back in the early 90's at 375 hp and they were very under stressed. So there is so much potential. Luckily I work for Case IH and we have a TON of cool parts for these engines in our system. My plan is to get it in the truck and then start exploring all the interesting parts I have available. As I said before this is going to be fun!
