My truck Not shifting into the high gears

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Heavy Truck Mechanic I'm going to connect you with knows all the tricks and shortcuts.

Ok

Mechanic's Assistant: Are you fixing your truck yourself? What have you tried so far?

The top plate on the transmission was broken so I replaced it thinking that was the problem

No
Technician: Wayne, Journeyman replied 7 months ago

Thank you for that

then your issue is the shift piston for the syrnco o-rings

are worn or torn you do not need to pull the trans for this

just on the back of the trans there is a cover it will have 3 or 4 bolt cover

remove that and get a rebuild kit for that

some kits are just o-rings other is o-rings and new piston

I hope this helps you
