Hi John,

I'd say that the first thing you should consider is an electrical fault rather than a mechanical one. As the automatic transmission ECU is under the bulkhead in the passenger footwell, check for signs of water ingress. Additionally, a T4 session to retrieve any fault codes would be interesting.

Xsport's posting is a realistic advice. The official diagnosis will almost certainly be a replacement gearbox. That's because:
  • It's the quickest and easiest way to get the car moving again.
  • Tracing the fault can be expensive in labour charges.
  • "Specialists" don't fault-find, they just do a standard reconditioning.

We once had a Metro whose automatic gearbox one day sounded like a bag of bolts. The "specialists" quoted £1,500 to recondition. I decided to find out what was wrong and repair it myself. The gear train unit (similar to a differential) had shed some teeth. I sourced and fitted a second-hand one plus I sent the brake bands to JPAT in Somerset to be re-lined. With a refurbished torque converter it ran better than it had ever done and at a cost of just £300 including the engine crane hire.

Of course in your case John, make sure that you haven't lost a significant amount of transmission fluid through a leaking cooler hose since that would eventually cause loss of drive.
