My transmission has been going into neutral and jerking sometimes when slowing down. Replaced the mlps and it did not fix it, got a new computer put it in and scanned codes. It did not come up with 654 (not in park during test). So I put tweecer on and did the writing to computer. Went out for a drive and it started going into neutral.

Could tweecer be causing this?
