Prevost 6v92 transmission

[BELMARR]

I have a 1981 Prevost with a DD 6v92. Right now it has a spicer 1062-b manual transmission. I have access to an Allison ht-740d off of a DD 8v92. What parts we would I need to swap them. Any issues with the bell housing etc? It came out of a 1979 MCI.

If your engine has a SAE 1 belling housing it will bolt up, the center plate is different on the flex plate 8v92 vs 6v92  but you are going to need a cooler, shift tower and a few more parts as you  go like drive shaft modification
