Removing and replacing the transmission on a 2002 Chevy Trailblazer typically takes about 6 to 10 hours, depending on the mechanic's experience and the tools available. This time frame includes draining fluids, disconnecting various components, and ensuring everything is properly reassembled. Additional complications, such as rust or damaged parts, can extend the timeframe. Always consult a professional for an accurate estimate based on specific conditions.

It is well documented in our forum at www.trailvoy.com It takes a few hours to complete and should probably include a water pump change if your truck is older and you plan to keep the truck for any length of time.

It can take between five and eighteen hours to change an automatic transmission in a Dodge Neon. It may take more time than that, it all depends on the person or group of people working on the change.

Mitchell labor estimating guide for a 99-2000 silverado 4wd 4.9 hrs and with skid plate add .2 engine and trans combos would make a little dif
are u sure is the timing chain? because cult it by the timing sensor or the timing auctueror sprocket There is no timing belt on a trailblazer only a single timing chain. After some research I found out that the timing chain is still in service in vehicles that have over 150,000 miles without issues. It does not appear to be a weak link in this very strong Atlas LL8 design. The posted labor to change it out is listed at 16 hours. Not really a driveway job but based on history not a problem on these trucks.
