Hi I am having a problem with my b16 tranny(hydrolic).. I have 4.05 pro m factory final drive with pro gear set.. There is no problem with the setup and the parts everything works fine but I am having broken my tranny case second time in a week... When I try to launch at firsth gear the bolt nut of the counter shaft loosen and the shaft moves left and right I think and hits the case and its broken... Then something happens beacuse of the movement of the counter shaft and it not shifts the second gear anymore. Other gears are okey... What could be the possible reason for this issue? What Do I have to do to prevent this..??.I am affraid of having broken my case again if I change the tranny case with the same parts installed again... The shift forks are okey- the shaft is okey - the gears seems okey and the case seems okey... I am using loctatite also to lock the nut on the shaft...

Sounds as if the bearing is binding need to check end play. trans should rotate pretty smoothly when assembled.

Nut should be tightened 11 kgms but i would go at 12... Secure it as best as you can.

Check the Shim clearances in the diff to housing. that's the only thing i can think of.

He has asked some photos from me... but I think I have found out the main problem it is all about the tranny case.. Inside the tranny case there is bearing guide which gets 2 of the counter shaft bearings inside. That surface of that part break down a liddle bit and it makes the ball bearing tighten and the bearing failures... In conclusion the bearing becomes pull to pieces and makes the nut loosen or etc... I am going to buy a new tranny case and again I am going to change all of the bearings inside the tranny.. This time if it fails again
I will try some sequential transmission or dog box gear set of Mfactory with a new tranny.

no the flanges are off the front of an explorer Rear shaft and will bolt to a 7.5 the shaft used is a front shaft with the rear flanges installed on it after the cv chunk was cut out

weld the F'n nut on the shaft after you torque it... I weld the spider shaft in the old b series all the time works great( the one with the sprung roll pin for retaining the shaft rather than solid pin.)
