C200 auto box not changing gear

Hi,my wife has a 1997 C200 and about 4 months ago it was stuck in one gear so I took it to a garage to have the oil checked. This was OK and the garage said the main ECU was showing a fault and I assume running in 'get you home mode'. The garage reset the ecu and this cured the problem. At the time they said that a new ecu board was about £700 and to have the old one reconditioned was £350.

The problem has now come back over the last two weeks. First time it happened I removed the battery connections and tied these together as I had been told this was the way to reset the ecu. This seemed to work. However this week the car has been sticking in gear but if you stop and turn the engine off and back on you have gears for 5 to 10 minutes.
The car has done 60k miles and only ever used on short journeys.

Current options seems to be sell the car (not my favourite as would feel bad selling as is and we do not really have the money for another car at present), go back to the garage and have an ecu fitted, but which one? Find an ecu and fit it myself (is this possible and how do you know if you have the right one?). If we change the ecu will that be a reliable fix and worth the money,I would hope we might keep the car for another 3 to 5 years.
Any advice gratefully received.

Would the garage give you a guarantee on a recon ECU?
