Re: 05 Ranger hard shift 2-3-4
Check your transmission fluid. Problems with the vacuum lines on a transmission have been known to cause hard shifting. Clogged, bent or disconnected vacuum lines affect the pressure in the transmission and can cause rough shifting to occur. The transmission control module on your car stores transmission error codes. If you are having a difficult time diagnosing why your transmission is shifting hard, you can take your vehicle to a transmission service mechanic and have these error codes read.
