I have not seen any other company offer a DIY option for valve body upgrades. In fact, Level 10 only makes the DIY for the A750E/F 5 speed auto, does not make it for any other tranamission, I don't know why.
The kit is optimized for high performance upgrades with smooth drivability, like a TRD or URD supercharger. What they meant is if you want it tuned for drag racing, for example, they can make it shift faster, at the expense of comfort.
There is also an Australian company that makes the upgrade, but they are ridiculously expensive compared to the US companies.

I would recommend IPT over Level 10.
Doublled, didn't you determine that your transmission issues were a result of the EMS you were using?

Gadget, I only learned about Level 10 from your personal website (Gadget online), and at the time you had good things to say about them. I wonder why you now prefer IPT over Level 10.
