1983 35-3 transmission info and recommendations

[trichards]

What type/brand fluid did you use ? The Hurth trans has very specific fluid requirements according to ZF. Please see attached bulletin from ZF. The schedule you want to use is "04D". I had some chattering in forward when I got my boat and have since used MOBIL DELVAC 1 ATF and so far so good.

My Trans says to use type A trans fluid.. as this is no longer made, i used a multi vehicle ATF that is advertised as being dexron and dexron II which is supposed to be a step up from Type A and backward compatible.
