Rear gear swap now trans slipping.

72 GMC 1500 truck with a junkyard stock 01 6.0ls and purchased new 4L65 trans 4 years ago only 10k miles at the most. Just swapped rearend gears from a 3.07 to a 3.73. First test drive after it has sat all winter and now trans is slipping like crazy in 1st and 2nd only above 2800 rpm. It's not in limp mode. No check engine light. Speartech did the computer and harness specific for the truck. Speartech says should be no problems with computer. And trans fluid is reading way too full on dipstick. Trans is slipping bad, almost like throwing it in neutral above 2800 rpm. Should I just pull trans??
