Ok so I had this problem a month and a half ago that I lost all of the gears but reverse and first changed the filter and got all the gears back now the flywheel broke took it all apart and now that it is all together only have second and reverse. Help is it the filter again or is it something else

 

When you replace the filter the first time. Did you notice a lot of debris in the pan? Pull out either the input or output sensors and inspect for metal on the tip of the sensor. If you have metal on the sensor, The transmission came apart inside. And if you have a scanner, Let know what codes you have.

 

There was a little but in the pan one piece was a bigger piece the codes were the speed control circuit and leak detection pump circuit

 

You should have other stored or active codes in the Transmission control module. The Powertrain control module will give you a P0700 code. That's just to let the person inspecting the vehicle that you may have codes in the TCM. Those are the codes I need to help you.

 

It doesn't have any other codes or I just don't know how to get to them.

 

You'll need a specialized scanner available at dealerships and many shops.
