Transmission Not Shifting Properly on 2001 Dodge Ram 1500

I have the transmission fluid and filter changed on my 2001 Dodge Ram 1500. Automatic, 5.9L engine. The mechanic told me he changed the fluid and filter and also adjusted the transmission. (Adjusting something on the inside and outside of the transmission for shifting properly. Ever since I had this service done, the transmission has to rev up to 3000 rpm before it shifts out of 1st gear. When I called him, he said just to put some transmission treatment stuff to it. I did. No Change. What is my problem and what has to be done to fix it?

there is two sensors under your transmission pan replace them and it will stop because one is a pressure sensor and when it goes bad it dont shift right on take off or when your put our foot in it it will slip

I had this same problem with my 2001 Ram. Seemed like it needed to get up to about 3000 - 3500 to shift out of first, then when it got to 45 - 50 mph, it wasn't shifting at all. It ended up being the Throttle Positioning Sensor, was like a $75 part. Has worked fine ever since.

Take it back to him and get him to fix his work. If that's no good, find a transmission shop or a Chrysler specialist. You may be able to recover your money if he didn't do a good job and you can prove it. Here's a directory link for you:
