Case 895xl drive/gearbox issue

[Carradale]

So in Gear driving along and loses drive as if it has jumped out of gear have to clutch down move gear lever into another gear then back again clutch up and away she goes.
Funny thing is seems to do it less coming up hill.any ideas ?

Have you got a (torque amplifier) powershift 16/8 transmission?

 

[Carradale]

I believe so has the switch with tortoise and hare

I had an electrical fault with our one but it tended to default to low TA intermittently. No slippage when left in low. The shift to high was positive but it would not stay there consistently. The op sounds like slippage on over run?

Been busy with cooling issues which i have now resolved Head skimmed /new gasket/ new thermostat/ new radiator seems radiator cores caused head gasket to go .
so getting back to lose of drive issue where exactly is the torque amplifier located please ? 895xl

Case IH 895 Torque Amplifier

Good morning all, nice bit of rain here at last !!. Here's a question for the case IH guys, torque amplifier failed and needs repairing. I have studied the service manual which explains the procedure in great detail. Will I be able to drive out the bottom PTO driven shaft out with the gearbox...

I not sure it is the TA, as it would still drive in low on the sprag clutch, an electric fault would not cut the drive on this model of tractor,
My guess it a locking stud on a selector fork has come out, allowing the fork to move the gear into neutral, yet enough moving the gear stick to another gear will reset its self with the synro cone, and enough grip to put it back into gear, yet vibration will shake it out , this tends to happen more in one plain, ie, going up or down hill,

To test it, have engine stopped, on level ground, press clutch in , and select different gears, see if they all feel the same, compared the one jumping out with others that are fine, see if there is a difference,
Failing that gearbox top off and inspect the rails and forks,
Think if you remove the carpet mat in cab floor, there will be a plate to remove, and then can get to gearbox top,
