Hey Guys,

I previously had an issue with my auto transmission as described in this post: http://www.ft86club.com/forums/showthread.php?p=2901959

Told the dealer about it and they told me there is a TSB related to this, so I went in to get it done.

I asked if this was this TSB: S-SB-0021-15. The service rep told me it is not the same, and it is an ECU reflash not a TCU reflash.

This guy also owns a frs so I asked him if I flash it with the OFT tunes won't it negate this fix, he told me that the transmission parameters will remain unaffected and the tune shouldn't bring the problem back.

Right now my car is sitting outside with the stock tune missing out on all the gains of the OTS stage 2 tune. Should I go flash it? How does this work?
