Transfercase on my 98.5 is bad its the 241dld, I found one off a 96 that is the 241 dld with 272 ratio and all that just like mine, was wondering though does anyone know if it would work on mine and bolt in right or did they change anything over the years?

the 241 to 273 will change your gears. I don't thank it will work if it was the same then it should work. Jest check the bolt pattern.

I am not sure if it will switch right over. After swapping out my auto for a stick, I had to tear apart my transfer case to replace the input shaft. You will have to check the bolt pattern to see if it will bolt on, but you may also have to swap the input shaft if it is coming out of an auto and going into a manual or visa versa. I would think though that it will work as my manual trans came out of a 94 and into my 99.

Arent the 12v shifters different too? I dont know if you can bolt up a 98+ shifter to a 12v case. I have heard the shift pattern is different also.

The bolt pattern absolutely will match. Auto and manual have different input shaft lengths, and diesels and v10s have larger dia and spline count inputs than gasser counterparts. I think available counts are 23 27 and 29, and the v10 and diesel both get 29 with any transmission but that part I'm not 100% certain on. You should be able to swap input shafts between the cases, it's just lots of snap rings and annoyance. New Venture's gear cut style changed during 1994-95 area, I'm sure in your case they're both newer than that and it's not a concern.
