Been looking at replacing both my trucks with a newer duramax, and i have a few questions.
i know that 06-07 lbz is the best motor. LLY's have overheating problems. Is it that common for the lly to overheat?
biggest question i have, i know they didnt put the 6 speed allison in until 06. Is it a big differance between the 6 speed and the 5 speed?
I found a good deal on a 05 with low mileage, but after reading some, i get worried.
Anything else to watch for besides the normal GM truck stuff?
thanks.
