Hi All,
Just wondering if this is a common problem......1989 Sierra Cossie 2wd.....................car has sat for a long time and found that all gears are good however downshifting from 4th to 3rd does not happen..... ironically going from 3rd to 4th is fine. Any ideas? Dont want to remove the box till i find out what the hiccup may be.
Any tips most welcome
