3/4 tons: Many will tell you these are the kings of the hill. Especially the 8.1 with the Allison. Absolute beast of a truck.
The 3/4 ton Suburban with the 8.1 liter engine was never fitted with the Allison, ever. Only the trucks received the Allison. The transmission fitted in the Suburban/YukonXL with the 8.1 was the 4L85e, which was an updated variant of the 4L80e that the 3/4 ton Suburbans with the 6.0L engine were equipped with.
I stand corrected. Thanks for setting me straight.
The few that I came across in researching this had RPO code MN8, which is the 4L80-E.
