Some history will help. New install? New to you or just starting to have problems?
Proper TV cable adjustment is mandatory with these transmissions. If it’s not properly adjusted you can damage the transmission in a matter of minutes.

Texas, Where are you from
X2 on above.
What does the fluid look and smell like?
If you pry on the circle on the pass side how much does it move in? Just a bit, a lot, none at all?

Are you sure the problem is between 1st and 2nd and not 2nd and 3rd? Need more details and history on the transmission and vehicle.

Under normal shifts from 2-3, the engine rpm’s drop.
When the engine rpm’s increase then drop or flares up between shifts is what’s referred to as flare.
Not the inspirational pins dorned by restaurant employees. Lol

Does your car have a bed code trans in it? On the rear pass side there is a plate that will have the letters brf on it.
Sounds like you need to make sure the tv cable is adjusted correctly . If it is and the trans has this behavior you will need a new set of direct clutches installed with the proper clearance.
