grinding when shifting into 3rd

so recently iv noticed when i shift into 3rd gear sometimes it will make a grinding noise...just like when u speed shift and dont make it into gear....it usually does it when i shift fast. it hasn't done it yet if i shift slower and when i shift quicker it does it sometimes....yes the clutch is all the way down when it happens...also it has done this maybe 10 times in the last year but these last couple days it has done it like every other time i shift into 3rd quickly....i put new atf in it like a month ago.

If it does it when you shift fast and not when you shift slow, it's your synchro slowing dying. Shift slow and take it easy on it, or learn to match the RPM to how fast you're going, essentially not needing the synchro's action so much. So when you take the truck out of second, let the engine come down a little in RPM's then shift, and when downshifting, take the truck out of forth, give the throttle a bump and shift.

no wonder its grinding... your trying to shift it like a race car...

try shifting slower and if that doesnt help then i agree with the post above that the syncro's are slowly going..

im not trying to shift like a race car but i just noticed it when i shifted fast and did it again and it did it so i came to realize it did it when i shifter faster...i done always shift like that.....but it hasn't caused me any problems like that today......but yesterday it was bad....but ya im defiantly going to take it easy on it cause i dont want to buy a tranny for a 3.0.....im waiting for the motor to go so i can out a 4.0 in and hopefully ill find on by then....and im not doing a 5.0 because nobody has found out a way to make a 5.0 5speed ranger yet...if they do then ill do a 5.0 swap....but until then is there any other things that i should not do that would shorten the life on my current tranny...ex "dropping the clutch" is that bad for it?...lol and what else?

umm.. the biggest thing is take it easy on it.. the clutch feels fine?? and its pushed into the floor everytime you shift right??? doesnt sound like a slave cylinder because you'd know if it was.. when mine went it leaked like a siv and i had to double clutch everytime i shifted up or down, sometimes had to clutch it like 6 times..

my guess is the syncro's are getting worn.. just keep fluid in it. thats probably all you can do without tearing it apart.. and if 3rd gear does go out then just skip it and go from 2nd to 4th to get you home.

i was driving a friends bush truck in the mountains back in january and was in 4low and went to shift into 3rd.. oh **** no 3rd gear haha so i shifted into 4th nope nothing there either... haha, the funny part was that there were no signs of grinding or anything.

ya i just put a clutch in it about 3000 miles ago....its fine....and nothing on the truck leaks a drop so the tranny should always be fine with fluid.

Definitely follow what I posted regarding rpms, that will help it last a tad longer, if you have questions regarding the shift pm me.

I'm having the same issue as well, I installed a
newly rebuilt transmission,
New clutch master and slave cylinder
New Flywheel,pressure plate, and clutch.
New pilot bearing.

While test driving it was easy to go into 1st at a stop but while in motion its hard to get into 1st gear. The same issue while shifting to 3rd, it grinds if I shift slow but if I were to shift a little faster and match the revs its fine.

I thought it would of been air in my slave or master but after reading so many post that are exactly the same, I beg to differ.

I find my '03 5-speed grinds when headed to 3rd if my rpms aren't up; if I try to shift too soon.
The slow shifting just allows a free movement of the synchronizes and let the gears mesh properly.
I think my Hurst Shift Kit helped some.
