6L90 no movement in forward or reverse

This is a disassembly or a tear down of a 6L90 automatic transmission for a no movement condition in forward as well as reverse range. While no movement can come from a check ball it is highly unlikely that two check balls will stick in the separator plate simultaneously. I have seen this failure before but it has only been on 4x4 2500HD work truck pick ups.

I have never seen an automatic disassembled so fast & easy.

Is it normal for the HD 10 spd gm transmissions to have a whining sound in gears 4-5-6?

Where are you located? Is possible to ship you the transmission to get that rebuilt treatment 6l80 from a 2013 tahoe

I HAVE A 2014 6L90 THAT I JUST REBUILD AND NOW IT DRIVES AND CHANGES GEARS GOOD BUT AFTER A WHILE OF DRIVING WHEN I STOP IT WILL STOP PULLING IN FORWARD AND REVERSE WHEN I TURN THE VAN OFF AND BACK ON IT DRIVES CORRECTLY UNTIL I STOP

I just bought a 2015 6l90 from a 2500 2wd. It will not go forward or backwards. The sfift selector feels odd. The output shaft will not spin. Sound like a shifter replacement?

[@esoterictransmissions]

Something is wrong internally

[@GrandPitoVic]

Thank you very much

[@cloudrhezii]

Would this made it seem like the transmission is locked up ? Tried to pull the truck in neutral and it won’t budge no brakes are hung up etc there is a engine code as well

[@esoterictransmissions]

If something is snapped in the trans it should always move in neutral. Try removing driveshaft and see if it rolls

[@cloudrhezii]

@@esoterictransmissions removed driveshaft and it moved only way I was able to move the truck out of the garage

[@esoterictransmissions]

@@cloudrhezii definitely something in trans transfer case or diff binding

[@cloudrhezii]

It’s definitely something in the transmission it’s 2wd and it rolled once I pulled the driveshaft . Im thinking torque converter or solenoids gonna look at codes and fluid today ! When you shift it to reverse or drive you can hear it idle down and try to engage but it’s completely locked up in any gear

@@esoterictransmissions the tip came off the parking rod and it was binding up getting stuck in park .
