Mine won’t go on 1st gear unless I gas it hard then it will jump and drive completely fine all gears but as soon as I go back to park it does it again.
Forward drum sometimes fails where the selective snap ring sits. It gives a little, then the piston has to travel a little further, resulting in slippage until enough fluid gets under the pistion to "grab". A new updated forward drum is available that is solid and reinforced where snap ring sits. Also the TRS can be shorting out to cause nuetraling out.
Bet first gear returns like normal now. Bam.
Dang right!
So can I do this myself ???

Did you ever fix it? I'm having a same problem.
