2003 Buick Lesabre 3800 V6 70K only on it. this problem Hard or long shifts it comes and goes, it seems when the engine is hot normally on a long run it starts with the hard transmission shifts, same as a P1181 code but no engine check light on yet , some articles say a MAP sensor could cause it what’s next any suggestions ?. ---

Years ago the torque converter lockup on a Pontiac I owned would act up when the engine got hot enough. Something similar _could_ be what’s happening to you. Not every fault triggers the check engine light. A good mechanic can probably figure it out by seat of the pants.
