So I have searched and can't find anything that fits my situation. But if I have missed something I apologize.
Lately, my automatic transmission seems to be slipping in 1st and 2nd gear. It does not happen all the time, just seems like once a month or so but it seems to be getting increasingly worse. It started out as just the engine rpms increasing but the tranny wasn't responding accordingly. It gave the feeling of the tires losing traction and spinning but there was no loss of traction. And then it stopped and acted just fine for over a month. And then a few days ago it started doing the same thing. But this time it was worse. Going from a dead stop it was almost impossible to get up a slight incline. But once it gets into third gear it acts just fine. This went on for about a 2 days and now it is acting normal again. I have checked the fluid and it it full and looks good. I have tried overdrive on and off, 4x4 on and off and nothing seems to help it. It has about 160000 miles on it. To my knowledge there has not been any transmission work done on it. I bought it used a few months back from a couple that had it serviced regularly and it was well taken care of. Any ideas of what could be going on. Is the tranny going out or what? Please help!!

Update: I noticed today that when trying to shift into 2nd gear if I am trying to accelerate anything more than slow, the vehicle will shake pretty severely.

 

Might be your battery, if it only does this when the car is cold and when you take off, I have experienced this same issue when the battery is weak. Once you get going and the alternator puts some juice into you battery all is good.
