Trans upgrades

All over the forum i have seen that our trans is the ZF6HP21/19Z or TU. On real oem it says a weird GA6HP19Z. On wikipedia it says we indeed have a 6HP26. Im not sure which is more accurate but the 26 is the trans that is used in the new 5.0 mustangs its just rebranded by ford as the 6R80. There are a few companies that build the 6R80/ZF6HP26 transmissions to over 1000whp and even companies that sell upgrade components. I believe parts can be swapped in from the 6HP26. In fact on this companies website it says "Sonnax Zip Kit ZF6-6R60-ZIP targets the root cause of multiple complaints by sealing the critical circuit pressure losses in the ZF6HP19/26/32 (Generation 1) and Ford 6R60/6R80 valve bodies."

so i think i am going to call a few places tomorrow and ask for certain if the 26 and our trans have the same internals and if so there has been a wealth of awesome trans options right under our noses.

according to this thread they are very similar and with slight modification we can easily upgrade our 21

so if i can get a confirmation im going to be going with either a local guy using some of this stuff:

Or using someone who does total builds on those trans like

theoretically the only real difference between our trans and this one http://www.youtube.com/watch?v=8Yxekmav2eQ

is that car has more clutches and slight valve body differences since the 21 which is in our cars is a gen 2 ZF 6hp
