Transmissions slipping out of gear are brought up by owners at roughly 75,000 miles. Usually it’s a sign of a problem with the third and fourth gears in the transmission, which cost around $500 to replace.

Most Sierra models from 2006 will have over 100,000 miles so buyers should be prepared to replace the air conditioning evaporator for $1,400, axle shaft seals costing $400, and control arms which cost $500.
It is very reliable. I haven't had any major problems since owning it besides the normal wear and tear. I would buy this truck again if I were looking for a truck.
I have put a rack and pinion on it. That is been the major repair on the vehicle so far. Everything else has resulted from age. I replaced the abs system on it, only because the previous line system had rust damage.

How Big Is the Sierra?
The 2006 Sierra 1500 series is a half-ton truck similar in size to the Dodge Ram 1500 or the Nissan Titan. There are three cab sizes, a 2-door regular cab, 4-door extended cab, and larger 4-door crew cab. Passenger space is good in the crew cab model, but cramped in the others.
Three bed lengths are available as well, including a 5-foot-8-inch short bed, 6-foot-6-inch standard bed, and 8-foot long bed.
How Does the Sierra Compare to the Competition?
The Chevy Silverado 1500 series is a close competitor, costing about $2,000 more. Both trucks are built on the same platform and share the same engines and transmissions. We recommend the Sierra since it has a nicer interior and is more affordable.
The Toyota Tundra is another rival, which costs roughly $2,000 more. Where the Tundra stands out is with better long-term reliability ratings, but the Sierra has a higher towing capacity. We recommend the Tundra since it will last longer as a used truck.
Do Owners Recommend the GMC Sierra?
Yes it has been a great vehicle. I have only needed to do normal wear and tear repairs. The engine and transmission haven't had any issues and I have owned this vehicle for almost five years.
It has been a great vehicle. The engine has held up well past 200k miles so far. It is just now starting to rust down on the fender wells.
