2003 Tahoe Transmission slips after driving for 5 minutes

Get it back to where you took it to be fixed ASAP. You should definitely have, AT THE VERY LEAST, a 90 day warranty. This seems like it's something that wasn't reconnected properly or at all. Good luck!

Not to sound condescending, but have you checked to see if you are low on transmission fluid?

This is called limp mode chrysler did this to protect the transmission without leaving the owner stranded by the road,a few things will cause this mainly putting the wrong fluid in the transmission,they use only atf+4,or the govenor pressure sensor is acting up which should cause a check engine light to come on,or the transmission just needs a fluid and filter change,should be done every 2yrs or 36k miles,due the fluid and filter change about 40.00 but if you have the wrong fluid then the whole system needs to be flushed and refilled-transmission-torque convertor,radiator and cooler if equipped and all lines.
