Shifts hard in Reverse and Drive P0701 Wrench light

Just changed the HP filter and Pan filter and new fluid.
Still get the P0701 Error, Wrench Light, and now, when it is put into Reverse or Drive, it shifts hard into gear. Press the gas pedal, and nothing, the RPMs stay at idle. Will not move or anything.
Any advise would be great guys

I thought you were going to 6 speed as trans was toast?

Was wanting to try and get the freestyle going sooner, so decided to try to change the filters and fluid and see what happens. Way things are going, may do the trans swap sooner than expected anyway, was wanting to wait for warmer and definitely dryer weather.

Could be mechatronic unit I tried one out of a wrecker transmission I got for some parts and when I installed it that’s what mine did. Really hard engagement but also in limp mode. With my original mechatronic. It would also go into limp mode until oil warmed all the way up then I could clear PO 942 code so I swapped mechatronic with one from Florida that advertises on EBay and now it works. My wrecker mechatronic showed po701. My original one never did.

Can a mechatronic unit be rebuilt?

The valve body can be Re worked but the TCM can only be replaced as far as I know.
