    Question Internal Part Compatibility between 20 Spline & 22 Spline T50 Transmission

    Hi Guys,

    This post is a little long winded so bear with me!

    I am rebuilding a 20 spline T50 transmission that I bought standalone so am not sure exactly what it came out of but am assuming that it was a Corolla.

    It is being transplanted into a Mk2 Cortina but Sleeve, Transmission Hub No.3 is worn (probably due to jamming into reverse while moving forward) and so far I have been unsuccessful in sourcing a replacement. I have tried Australian toyota dealers, US dealers and Amayama in Japan with no success.

    The part is a 33395-14010 which was replaced by 33395-14012.

    I recently discovered that in the T50 fitted to the Corolla between August 79 & June 81 another part number (33395-14013) is listed which carried through into the later 22 Spline boxes. Does anyone know whether this would be compatible?

    I have checked a few web sites and they are listing a 33395-26010 as a replacement for the 33395-14013.

    Any help would be appreciated.

    With respect to my particular situation the question has been partially answered. Will know for sure on the weekend when the alternative part is installed.

    Hello, I know this is a pretty old post, but I am struggling with the same problem. I am also working on a 20 spline T50 and can't find the No. 3 hub sleeve or the syncho-mesh keys that go with it. Did you ever figure out if that alternate part number (33395-26010) works?

    I searched hi an low for the syncho mesh keys, about three years ago, could not find any. I think the only option is used parts! Dave W

    It has been a long time but yes it did work. I still have the car.

    FYI I purchased it from Amayama Trading Co. Ltd. (http://www.amayama.com/) in Japan and I was dealing with a guy named Justin Karow.

    I still have their email from 18 May 2011 and this is the extract from that email.

    >> Part numbers that have changed (same part):
    33395-14013 - Sleeve, Transmission Hub --> 33395-26010
