As long as I'm taking over the board with my questions.....


Anybody have a good sense of how strong the tranny/transfer case combo is on these P'up drivetrains? Mine is out of an 81--the 4sp 4x4 option. I have been taking my jeep with this transplant drivetrain out on the trail with my jeep buddies, and it's doing awesome. The only time I got stuck, it was a traction issue (I have smaller tires than everybody else, and some of the trails are just so rutted from the big tires that the little tires don't cut it anymore). But just from an external observation, this married tranny/transfer unit doesn't look anywhere near as strong as the t18/spicer 20 combo I have in my Jeep pickup truck. And given the fact that this tranny/transfer came out of a light duty pickup, I'm curious just how strong these guys are? Am I riding a risky line by taking this drivetrain offroading with 31 inch tires?

I've been super impressed with this engine/tranny/transfer so far, so I'm expecting the answer to be "don't worry about it," but I thought I'd tap into the knowledge here just to double-check.

Thanks once again, all,

lamby, the 4-speed 4x4 transmission/transfer case is considered to be the most durable transmission you could get behind the C223 diesel. It is not like the 5-speeds you tend to find in the 2WD diesel pickups which usually had problems after 150k miles. If Jerry replies he'll tell you the 4-speed is basically bulletproof. I remember him saying it in a past post he made in a thread. As for putting on larger tires I say go for it. I think the diesel will handle 31" tires without much problem and then you'll be really doing well on the trails. <img src="/forums/images/graemlins/smile.gif" alt="" />

RIGHT ON SALVY THE 4SPD IS MUCH STRONGER THAN THE 5 SPD WITH IN REASON THE TRANS FER CASE IS PRETTY STOUGHT , MANY YEARS AGO ADVANCE ADAPTERS MADE A CONVERSION KIT TO PUT THAT TRANSFER CASE ON THE BACK OF A TURBO 350 FOR USE BEHIND THE V8 CHEVY, FOR USE IN THE LUV TRUCKS THE MID 70.S STYLE AND THEY NEVER SEEMED TO AHVE A PROBLEM WITH THEM JERRY

Ha! That's great news. I will cease to worry about that part of my rig starting.....Now!

I'm really glad I chose this isuzu engine/tranny combo for my jeep
