i was cruising in my mustang at about 70mph when i felt the transmission was shifting from 4th to 3rd on its own then shifts to 4th (shifting a lot although my foot didn't move)
i stopped in the nearest town and checked the trans
oil level and it was low
i refilled it and continued my travel and after about 10 miles i noticed a lot of
white smoke behind me , i stopped and there were almost no oil in the trans
and it was leaking from the transmission extension to the drive shaft
i put the lever in D , R , 1 , 2 and it didn't move or anything
the oil kept leaking for about 2 hours and then stopped
i was told that it was an easy fix and its the sealing
my question is :
how hard is it to replace the seal ?
how much does the seal costs ??
do you think i damaged the transmission ???
