Hey I got a 06 GT Auto Transmission and my reverse Drive and 3rd gears is gone, it wants to move but just can't, I swapped the Solenoid Pack, and I got both Drive and 3rd gears back, but reverse is still having an issue, Drive is sluggish. Any ideas what I need to look at?

umm fluid level? correct fluid? autos are sealed so hard to check fluid level but a starting point at least. good luck

Try to get a code scanner and see if it's throwing any codes.

reverse has it's own controller/servo.

It's the big roundish thing sitting on the opposite corner of the solenoid pack. I'm guess you didn't touch it when you had the pan dropped?

It's known to accumulate gunk in it that makes it stick. In some instances the diaphragm seal can get cracked and render it inoperable.

Drop the pan again, remove the revers servo, dismantle it and clean it out. If the diaphragm seal has any cracks in it, you'll need to replace the diaphragm. The diaphragm is the Top looking thing that goes into the spring.
