Automatic transmission won't go in reverse
I have a 2004 Chevrolet Impala. All of my automatic gears work except "reverse". I did fill with transmission fluid - still no reverse. Any suggestions?
Have a local mechanic diagnose it for you. If you added fluid, I assume you are leaking fluid and it might have been running low heating the trans up beyond the normal range.
Common causes of this problem are a blown sealing lip on the reverse servo, worn reverse booster valve/sleeve or a partially blown channel plate gasket. - See more at: http://etereman.com/blog/uncategorized/a-history-lesson-on-the-gm- 4t65e-transmission-and-discussion-of-some-common-problems-and- their-cures/#sthash.8c3pNAh6.dpuf
The rear sprag could be a problem too, as it has to hold the low/reverse pack, but only in reverse. It freewheels in forward gears.
