hey, had my jato 3.3 out running good fast speeds today, then lost almost all forward drive. seems like clutch is slipping. Could it be because i have been running it in -7 degree celcius weather? i was thinking the slipper clutch just needs to be adjusted but was not sure

Several things may be happening. First check your clutch. My clutch went bad after I installed a new motor. Luckily I had a spare and so far so good. Also check the spur gear and the gears in the tranny to make sure everrything is ok. Also open you diff and make sure that is also ok. If you have any stripped gears they are not expensive to replace.
