2005 Trailblazer EXT 4.2 straight 6, 4WD
About a month ago, I noticed that the transmission was starting to drop out of 4th during normal highway driving. Immediately took it to my transmission guy. He checked it out and said it had a slow fluid leak. He disassembled and cleaned the transfer case, put in a new seal kit and filled it with fluid (over $450). Thirty minutes after I picked up the TB from the shop, I was back out on the road when the transmission dropped out of 4th again. Immediately took it back to the shop and left it for them to road test it. EIGHT DAYS LATER, he called me and said they couldn't duplicate the problem, and the diagnostic showed no transmission errors (no charge, but a shitload of inconvenience). Since then, I can only drive short distances before the transmission starts dropping out of 4th, and now the engine is overheating badly (bubbling hot for 15 to 20 minutes after I stop). I hate to do it, but might have to go back to the transmission guy again, because he's the only one with a "good reputation" in the area. Before I do, I just want to ask who else in here has been through this (with these symptoms), and what did you find out at what cost?
