Really... So did you replace the wheel speed sensor and did you finally get a fix on the slip light staying on? When he scanned my truck code P0106 came up along with P2637 which is a torque management feedback problem with the transmission. After replacing the first map sensor only the P0106 code came back and also an ABS code but not the P2637 code. Are you running your truck tuned and deleted?Well - for me, I did not have the specific issues you report with lunging forward.
I will say: some subsequent issues ended up being an intermittently bad right rear wheel speed sensor (which was causing ~11 codes, 6 ABS and 5 CEL).
