5r trans problem??

[03 tx pwr stroke]

When the rear tires break loose, like wet roads etc, the trans will sometimes either stick in a lower gear and refuse to upshift until I slow WAAAYY down or will act like it's stuck in neutral until I slow down. Trans is a Ford OEM replacement, only about 8k miles on it. I am running Gearhead SRL non-studded tunes. Is trans taking a dump again or is this something that can be easily taken care of like a solenoid? :shrug:

No ideas?

Probably limped because it detected a slip when the tires hooked back up.

Sounds like clutch slip, a solenoid will help if the damage isn't already done.
