I've noticed with my box now, after having the "A-Drum" replaced by VMT and then a solenoid replaced, the gearchange is now smoother than it's been for a long time, particularly in the morning when it's cold, there is no longer a lunge into gear from cold start.

However, I still don't trust it. It does funny things now and then, like changing down at odd times and in particular it does this one thing at high speed under full throttle whereby it misses a beat, like it wants to change down but in a split second decides not to. Usually this happens above the 4k rpm mark at full throttle in top gear, in D or S.

Also, there was one time it definitely went to change down from 4th, spent about a half second thinking about it then decided to stay in 4th for a few seconds, then changed down to 3rd smoothly. Hard to explain really, there's no jerking, it's like a manual clutch slipping very slightly before it either stays in gear or changes down.

I've decided I'm going to give it a few months still to settle down after the recent jobs, then re-assess what I'm going to do with it. I wish there was a manual conversion option, as it would be a fantastic motor and more economical with a manual gearbox, but ah well - we'll see how we get on
