case 850b crawler

Nassau Bill AJ,
on our 850B crawler, it doesnt want to move, feels like a resticted flow, it will engage forward and reverse, but locks up, we have changed the pressure pump to torque converter but same results, our next test is pressure tests, i have the service manual so i know the specs, just any advice would be great ?

AJ Have a look with the engine running if the drive shaft is spinning,both in and out of gear,if the shaft is stopping the issue is in the torque,if it does not stop the tranny could have a fault,check all the filters for metal,check the machine will move,the brakes are free etc.
AJ

Nassau Bill You are correct, the driveshaft stops when forward and reverse are engaged, but feels like it wants to move but doesn't, we serviced all fiters and all are very clean, so we are removing torque converter, to get it repaired will be another story, thanks AJ !!!!
AJ Could be anything from a blown gasket to a sheared spline in the turbine,nosing about on ebay there are lots of new TC's and parts for the 850's,the link below might work.
