After replacing MAF sensor the transmission is not shifting right at all. Do I need to reset PCM?

Hello,

If you replaced the MAF and now the transmission does not shift right it means the MAF is defective. I would stick to name brand replacement parts like Motorcraft and AC delco.

Here is a guide that will help.

Please let us know what happens.

Cheers, Ken
