2008 Trans problem??

[gsstuart]

Recent problem. When up shifting the transmission will slip momentarily about 1000 RPM and then drive fine. Also recently the traction and stabilitak warranty is appearing randomly. At next reset no lights on. Check engine light on with the following codes0403, P0451 -- Pending B2AAA, Po305, P0405, P0446.

It almost acts like it is low on trans fluid. Sometimes when hard turning to left the trans will slip.

Anyone have any comments or tips on where to look first.

Thanks to All.

have you checked the fluid level and the color/smell?
how many miles since the fluid and filter were changed?
this is a link for the codes with possible solutions, some of them are related to each other, the EGR may effect cylinder 5.
