quick warranty question

[enobmort42]

i brought my car in to a dealer at approx 20k miles, under warranty, with a squeaky shifting problem. it took them several "small fixes" to correct the problem, the last time being at 37k miles, out of warranty. they had no problem writing it off as warranty work. i kept all of the paperwork and invoices, too.

now i'm at 70k and i'm having the same exact symptoms from before; squeaky shifting from 1st/3rd into neutral. i brought it into the same place that put a bandaid on it before and was told they won't provision this into the warranty. i asked if they guarantee their work and was told "only until the car's warranty is expired. if you bring it in at 35k miles, the work is guaranteed until the end of the 36k mile warranty."

is that right? i was under the impression that there was a toyota-backed lifetime warranty on all labor or parts or something... am i wrong?
