Does anyone else have a problem with there 2nd gear between 1500-2000 rpm? I got the TSB fix for the 3650 tranny, but now if I am in 2nd gear around 1500rpm and give it some gas, I hear a clashing vibration sound from the tranny. As soon as I hit around 2000rpm it goes away.

Does anyone have any ideas or have this problem?
Thanks,
 
Well I took it in and got the it's normal speech. Saying it is gear roll over and it happens in all gears at that RPM. They said they have had other customers complain about this with the 3650 but there is no fix for it from Ford.
My car had the TSB fix... but they found a hairline crack in the housing so they had to replace the housing and re-install all the tranny componets.

Thanks,
