Manual Transmission problems Sign In

I have an 03 Ford Ranger Edge Regular cab 5 speed manual with 117000 miles almost on the dot. Just bought it 5 days ago and come to find out it had a wierd transmission issue. In first gear it will get all 6000 rpm out no Problem. 2nd at around 4500 begins to almost let go of the gear and then grab back on hard and causes a bucking like motion in the truck. In 3rd, 4th, 5th it does the same exact thing at only 3500 rpm And I can't simply power through it. I have to up shift to get it to stop. At 3500 in 5th I'm at 75 mph when I have roads with speed limits of 80. No one seems to know what it is. Let me know please and thank you.

Check engine light on?

When it "lets go of the gear", does the engine rev higher? Like the clutch is slipping?

Not that I've seen, I'll pay closer attention tonight on my way home from work.

It revs maybe 300rpm higher before it catches again. This is all while I'm already driving and have the clutch fully released but could it still be the clutch slipping?

Re: Manual Transmission problems Sign In

If your holding the clutch pedal down, which disengages the transmission from the engine, and the bucking is still happening, it probably isn't anything to do with the clutch slipping.

There are two common things that can cause bucking. Slipping, chattering clutch, or an engine misfire. They feel kind of the same, but a slipping clutch will cause the engine rpms to increase when the slip occurs and a misfire will cause the rpms to decrease at the moment the misfire occurs. If it is a miss, it may not be missing enough to trigger a misfire code.

It is important that you determine if it is a miss or a slip. You may need to have your mechanic take it for a test drive.

Any particular reason you hammer this thing all the way out when you drive? Beating on a truck is a good way to have it turn into junk.

The check engine light does not come on and the rpm does not go up or down. And yes the check engine light still works if I just turn the key so it is on but the engine is not running. When it bucks and I push in the clutch it stops and let's me shift.

Yes, I have short entrances onto a 70 mph highway. I don't particularly have a death wish by entering a highway at 45mph.
