H1 5 speed transmission on a 6.5L
 

Hello,
HAs anyone seen or heard of a 5 speed automatic trasmission in a 6.5L H1? I do know that the suburbans have 5 speed automatics in there 6.5L diesels. Does anyone know if this is a possible swap?

I think you are mistaken.

What 5-speed automatic do you "know" was offered in the 6.5l diesel Suburban, and in what year?
To my knowledge they offered 3 and 4 speed automatics, and a 5-speed MANUAL transmission.

In the Suburban the 4-speed 4L80E was the "latest and greatest" automatic transmission offered with the 6.5l diesel motor; same as in the H1.

BTW, why would you want a 5-speed auto in an H1? Do you feel that the gears are too far apart for optimal shifting?
