Are you sure abot that? Chrysler started to use locking TC's in about 79-81, if my memory serves me. I recal it was later in the trucks, but I don't know for sure.

Maybe in cars but I am 110% positive that the CTD/a518/727 tranny does not have a locking TC. In 94 2nd gen new body style with the 47rh(?) had the locking TC.

'94 was the first year for a locking TC behind the Cummins.

Durn overvalvers coming in the 1st gen forum and confusing the newbies!

In 1991 you could get a 4 speed lockup tranny behind a gas engine in a truck. I just did a quick search, that was in a 250 series truck.

Yes, on a gas truck. Not on a Cummins. They didn't even get a 4 speed until mid '91.

You can retro a 94-95 47RH into a 1st gen, with the engine adapter from a 94 up Cummins. The same tranny came in both the 94-95 Cummins and V-10 trucks.

If you use the v-10 tranny, do be sure to change out the governor weights unless you have the 4200 rpm spring in your injector pump.

I can tell you guys that the conversion to a NV4500 is close to $6000 - I just priced it, and then I dang near crapped myself... That was with all new parts, but I'm not sure I'd go through all the trouble of doing it with used parts, either.

I'm currently investigating a conversion from my 518 to a 47RH (618), which will also allow a 1st gen diesel to have a lockup converter...
