Overdrive Problems

I have a 1966 Auston Healey BJ8. With the overdrive engaged I downshift from 4th to 3rd and as I apply the brake the overdrive disengages and then as I accelerate (still in 3rd) the overdrive engages again. Otherwise The overdrive is functioning properly. I am using 30W/ND. Any suggestions as to why this i happening and what the fix might be.
