48re has no gears!
I need some advice here. I have a 2003 cummins with the 48re. 1st gear was starting to slip really bad and was hesitant to shift into 2nd gear. So, I pulled the valve body out, put a shift kit in, installed the modified borg warner solenoid and a new transducer, and adjusted the bands while i had the pan off. After putting it all back together, I have nothing in any gear... I can feel it engage in reverse and drive...but that is all it will do... the truck won't even move... any ideas??

I tightend both bands to 72 in. lbs, back the front band screw off 1 3/4 turns and the rear 3 turns. Tomorrow I will have time to work on it again... i will double check them. I am hesitant to remove the modified gov. solenoid and put the stock one back in...because i was having a shuttle shift before... The shift kit came with a modified spring for the top of the accumulator piston and a reducing sleeve for a port that leads into the accumulator chamber. My accumulator piston did not have a spring on top when i took it out, only on the bottom. Also, that reducing sleeve seems very iffy to me... Think I should leave the Accumulator piston stock?

Accumulator is just a buffer for the shift points, won't stop it from moving. Same with the gov solenoid, its just controls shift points. If it won't engage at all then likely something was done wrong in the shift kit or it broke something in the trans.
Need to pressure test the 3 ports on the passenger side. Front is direct cluthc pack, middle is line pressure (sort of), rear is first gear and reverse apply pressure. See if you have pressure in those ports and what it is.
