Hi, anyone had any problems losing forward and reverse drive on a MF 4200 series 24/24 Power Shuttle 4255?
Any info very welcome.
Thanks

I have a 4355, it is a 2004 model and has the 24 x 24 transmission. Two years ago it fried the brain box. Sometimes it would move but not very often. It was also flashing erratic codes, seemed like a different one on each attempt to move it. The dealer had a similar tractor on his lot which he swapped brains. That cured it so I ordered new brains. So far it is working good.
 
Hi Eric, thanks for your reply. It is a customer's tractor. It suddenly lost forward drive whilst towing a load of hay. I have done the pressure checks etc and all are reasonable. In addition to no forward drive when the reverse shuttle is engaged with the main lever in neutral the engine will stall within about 3 seconds. It is flashing 5+2 and 6+2 which are the cooling oil solenoid and road speed sensor. Range box seems ok. It is suggested that the F and R clutch packs may be faulty by those more knowledgeable than me but I don't feel that we can rule out the control unit yet. Anyone else had any reverse lock-up problems? Thanks in advance.
