    ATF billet accumulators and shift kit cracked a340e

    Troubles with my A340E... I bought ATF billet accumulator pistons and a trans go shift kit, had transmission shop do the work. After reinstalling the transmission I noticed a leak after driving it for 5 mins... No boosting even.

    I'm just concerned why this happend I got another case and I was gonna swap everything over again. Is the shift kit too much pressure for the case with the accumulators?

    I just don't want to crack another case.

    Did the shop machine to fit the pistons in? I believe atf does that in house.

    Very weird, I've never seen that before!

    I have the billet accumulators in my A340E (MK3 version though) and they push right in. With difficulty, because there's 4 or 5 orings, but no machining required.

    Not pointing fingers at you but did you follow the shift kit instructions correctly? Any way to verify line pressure? 300 psi of line pressure could crack something. Either that or a casting flaw that didn't break until now.
