Default Re: Just rebuilt transmission

I agree with previous statements about adjustment. There is a problem if it it shifting into high at 40 MPH. Transmission shops should be equipped to check the pressures and they should be the ones to get it right or lick the calf over again. The type of fluid used is likely the least of the worries.

If they don't have the original Ford transmission publications or equivalent, a person might try to get the info and let them read it so they won't try to tell a person otherwise. I had a long working curve with the later cruise-o-matics that had the vacuum modulator of the mid 60s when I started having problems with them. I purchased all the info but a friend of mine who was taught transmission work as a kid by his father helped me shine a better light on these old units. Even the later Ford AOD transmissions were set up to work like the old cruise-o-matics & FMX transmissions since they used the ravigneaux planetary set ups and a TV cable for pressure control just like the old timers.
