If you are having issues with the lock up in the converter, i would try this additive before replacing it. This is similar to the sure grip additive in that it stops the clutch from chattering when engaged. I have used it with great results in numerous trans in lots of different makes including the 46rh/e.

There also is a newer clutch material raysbestos makes for our overdrive units


The red eagle stuff I asked about earlier is a thinner material combined with thinner steels that allows more clutches in the same drum. The raysbestos frictions are just a different material with increase grab and might be a better choice. Not sure and welcome any input.

For sure servos, shift kit including sonnex fix that allows oiling in park, and widest bands available are agiven for me. Also updating to the borg warner solenoid as well.

There are some really good youtube vids on the rebuild.I have not done a 46rh, but have build numerous 727s in the past. Basically the same save for the overdrive.
