Topic: r150f input shaft question

[EJMFS]

Ok, so I'm new here in this forum so I can't post photos yet.  I believe what I have is an R150F but I haven't found any numbers on it yet.  It came from a 94 3.0v6 toyota pickup.  So I have the bearings and clutch kit for it and when I slid the pilot bearing over the shaft I realized that it fit really loose.  I know this isn't ok.  Also, the input shaft has some looseness when I wiggle it.  I am guessing this is not ok but I am not a transmission expert.  How much play is allowable in the input shaft?  It has a little bit of looseness in the shear direction but in the axial direction it is tight.  Any help from experienced people is appreciated. 
Thanks

a little play back and forth is normal. it does need some play as to not bind up when it gets hot. the up and down is what i would worry about. also those transmissions need the bearing retainers replaced with stronger units. Marlin makes them. and also the thrust washer between 2-3 fails and destroys the trans. i would recommend bearings, syncros and the stronger retainers and washers if you plan to abuse it. or if you just plan to drive it nicely probably just a front bearing. its easy to change. you just need a press. I recommend Redline oil as well. I use MTL gl4
