Sometimes stuff just breaks. I had my glide rebuilt 60 runs back. It had the biggest input shaft available put in. Its a $5000 trans. Well I figured it was due for a freshen up. Just got the word that the input shaft is twisted; the planetaries are stuffed; and the output shaft is twisted; the keys are destroyed. Who woulda guessed at so much carnage. My builder said he can't believe it hasn't flown apart yet.
That trans has the best of everything in there but s*%t still happened.
