Posted June 1, 201114 yr My 47re has recently started reving a little higher before shifting from 3 to 4. Its only reving up a couple hundred rpm higher but still something isnt right.
June 2, 201114 yr If i remember correctly 3rd to 4th is shifted by a solenoid. Almost sounds like a voltage problem. When was the last fluid/filter change? If the solenoid needs to be replaced you can do the fluid/filter at that time.
June 2, 201114 yr Author I was thinking the same thing. I have never changed the fluid as it is still nice and red from the recent rebuild.
June 3, 201114 yr If you can ,ask the tranny guy if he replaced the solenoid that shifts it. Maybe it is something we are not thinking of ?
