I put the transmission fluid in it, then was driving it and then I give it gas and it started like slipping like it didn't want to go but it did but I'll give it a lot of gas to go and then once I parked it and started back up her leave again. Now it won't go into reverse like the shifter will go in reverse but it does it if I step on the gas it doesn't want to go backwards and might want to go forward.

The slipping and no engagement at this point sounds like a pressure issue inside the transmission. You have a pump in the transmission that maintains the proper amount of pressure needed to apply the clutches that engage each gear. I attached the system information about this system for your review.

Let's start with checking for codes because this could just be a bypass valve issue but if the fluid is full then I suspect it is an internal issue. If you can, let's check the line pressure of the unit and we can confirm proper pressure. I attached the spec for line pressure and the test port location.

Here are a couple guides that will help with getting codes and if you don't have a scan tool then just stop by a parts store (if possible) that does this, and they can scan for codes free of charge.

Let me know what they are and we can go from there.
