I have a 05 GTP. The other day while pulling a steep moutain the tranny started slipping. After coasting down the mtn the engine died and stabilizer light and traction control light come on. After getting the engine started back after a couple of attempts the car pulls fine with no slippage put the trans temp stays hot at 221. Engine temp is fine and no more slipping or fault codes. 77000 miles and only problems up to this is cataylic converter and heads up display. Any ideas ??????????
