Just had new Jasper engine put in our 2006 Limited. 250 miles later she seems to not fully downshift when slowing for a turn at intersection. Seems like it's either hesitating, bogging or staying in 2nd. If I get on it she will kick down then seems to go into 1st and take off. Upshifts fine. Today I was slowing at the top of freeway exit ramp and the engine dies. Starts right up again and doesn't die again but still seems boggy when getting on gas after almost complete stop. If we stop completely it takes off fine.

No lights came on dash but a pending P0700 is present.
