Limp Mode DTMAL- only odd number gears work (1, 3, 5, 7)

[TheHouseWon]

180101 code (catless) popped up then the car wouldnt shift out of 1st until I picked up more speed. It jumped from first to 3rd at about 25 mph.

This happened under normal driving conditions.

I have since restarted it and DTMAL is gone. Gears also working normal.

I have JB4/BCM, RK Intakes, and catless dp's.

Some tranny issue - need ISTA as JB4 won't read all the BMw specific codes. Swing by I can scan for you!
