Diffs
You said you applied grease to the diffs.
What kind of grease?
If you don't use the correct diff grease and don't tighten the diffs correctly again afterwards, the diff balls will slip. This will also wear out the diffs very quickly.
Try disassembling the diffs and see whether it looks like the balls are slipping. If you used the wrong grease, you'll need to clean it off completely and reassemble using the correct grease. Also check that the balls are still round and that they have not worn grooves into the plates.
The manual also shows you how to test each diff for correct tightening. You can take the diffs out and test that they don't slip before disassembling them.
Apart from that, you can see where the transmission slips by holding the car with the body off to the ground and gently applying throttle for a very short moment. Where does the drive train stop moving? Of course, doing this for more than an instant with more than a very low throttle may very well wear out or break something, so be careful and keep the car pointed in a safe direction.
