Add a bottle of Lucas Tranny Additive & I''ll bet you get plenty of more good use out of it.

it might not be your trans at all. trans performance is based on engine performance. your puter reads a ton of info and adjusts the engine and trans to run together, if you have engine performance problems you will have tranny problems. your problem souns typical for an engine performance problem. when waas the last time you had your oil changed?

That is good info. I will store that for later on.

There''s a quite a few different things this could be steming from. The first thing you should do is to check for any trouble codes. Auto Zone, or just about any auto parts store will do this for free. From there you can get better advice as to what is the problem. My truck was shifting harshly from 1-2 like that as well. I had the trouble codes pulled and it turned out to be the code "P1870 - Transmission component slipping". I did some research and found out this is often caused by a faulty solenoid in the Valve Body Control. Tons of information on the forum once you have a Code to direct your search. With the information I found on the forum here I did the repair myself and it shifts nice and smooth now. Good luck.
