Hello, I need some advice on my 2005 E46 325iT. This has been my daily driver for last almost 10years; there is about 126000 miles; and I have followed the recommended maintenance schedule with shortened oil change intervals. It has started to develop on 'odd' transmission quirk: sometimes upon a cold start it does not seem to fully engage in gear. If I rev it hard for a few seconds, it will kick fully into gear. If I was driving a manual, this would seem like I was riding the clutch. Once transmission fully engages everything runs as normal. It may be that the transmission has warmed up. As I said, the problem is intermittent and do not know under what circumstances it decides to act up. I have seen some online info stating certain GM auto transmissions have a slipping problem but it doesn't state what the 'fix' is. I have not found a local (Seattle area) transmission repair other than to completely replace it with a BMW rebuild (about $5k; not particularly palatable given the car's market value). Can you please help diagnosing and/or recommending a path to repair? Let me know if you need more info from me. Thanks and I have enjoyed reading your columns for the last 10+ years.
