Welcome to the garage.
Presume you have a 4.0 engine with 42RE transmission.
These 2 codes are from the governor pressure sensor and solenoid inside the transmission. Normally they pop up when you really have some shifting problems. Since you don't have them (yet), i think the best is to reset the codes (with a scanner, or just remove the negative battery cable for a minute or so) and see if they come back. If they come back, you probably could better change these 2 components. There could be a line pressure problem and clutches/bands could start slipping without you noticing it now, but it could wear your clutches/bands in a short time. If you ever need to change the governor pressure sensor and solenoid, here is a writeup: 42re, P1762 and P1763, Governor pressure sensor & Solenoid write-up - JeepForum.com
