doing the fluid and solenoid replacement - shot in dark possibly
I have been reading these posts and others for the last 4 days. Went ahead and ordered the TCC solenoid, and will prepare the flush, fill, solenoid replacement soon.
I know by reading this, it works for some GM's, improves other, and doesn't help if the problem is in the valve body.
If it doesn't help, I will probably do a follow up flush and fill as I have read that has improved the improvement of successfully shifting with fewer no reverse issues (better odds)
Has anyone removed the valve body themselves... or if mine is still bad, should I order the rebuilt valve body and pay a transmission place to remove my old one and put the new one in.
I am pretty confident with auto work but limited to fluid, accessory, some suspension, tune ups, etc.
