Clunking in/out of 1st after Mackies Flush

[Turbo Tony]

My work brought me to Glasgow and I thought I'd make use of the time to visit Mackie Transmission and get the transmission flushed and the gearbox software updated.

I got a call to say the car was ready. They said they couldn't do the software update because my gearbox had the latest software. I got a cab over there and drove away a happy guy. Even from startup, everything seemed that little bit smoother and pulling away felt great. I happily drove back to my hotel... until I had to stop for the first time after the car had warmed up.

When the car shifted into first while slowing down, there was a clunk from the transmission. Pulling away from a standstill and, when shifting from 1st to 2nd, the car hesitated quite violently before shifting to 2nd and then behaving normally.

I tried calling Mackie but they had closed for the day. I emailed John but got an out-of-office.

I've decided to drive there first thing tomorrow morning and hope, pray and plead that it's something they can fix easily. I'm due in Sheffield tomorrow afternoon and, truth be told, I'm freaking out.
