I called the shop that rebuilt my motor and they told me it would be cheaper to buy one but I have 3 and would rather rebuild one so i will know my tranny is new. I'm not sure why my inputshaft bearing keeps failng? The shop told me somehow I am installing it wrong and it is stressing the collar I dont see how but if i get them to install the tranny nest time they want $500 and up. By tha way 2g dad is my I He's better at computers and i cant find the time to get on here he has much more knowledge than i do. lol
