But it is noticeable. Something doesn't sound right about this explanation. It seems a little crazy to suggest someone would break open a transmission and replace a gear with the wrong one, like they had a second fourth gear just laying around.
Doesn't it?

I agree. I suggested it with that exactly in mind. Hoping to exhaust all other possibilities because the reality is, why in the world would someone even consider doing that and besides that, is it even possible? <img src="/forums/images/graemlins/kewl.gif" alt="" /> I doubt that gear has been changed. Seems the most unlikely thing but then again ricardo's in Mexico and I'm sure they've done stranger things because alot of times people will improvise and adapt using what's at hand to repair a vehicle. Ricardo, has it always behaved like this after you purchased it? Did you buy it from a car dealer or the prior owner? Maybe either can tell you what's up with it.

No idea if this is possible, as I only opened mine up once when the 5th gear went out after the tailshaft nut came off. (Not that that makes much difference in that I am pretty lost on how the gears all seem to do what they do. <img src="/forums/images/graemlins/cyclops.gif" alt="" />)
Is it possible for something to be broken in the shift forks? Something such that even though the shifter is going from 4th to 5th, the tranny itself isn't doing anything inside? My first thought would be no, and that you'd end up in neutral once you moved out of fourth.
Say if the fork that engages fifth also disengages fourth, and if that fork was broken off...?

Fourth is direct and shares a shifter fork with third, fifth shares a fork with reverse. So if reverse works then fifth should work, same with forth and third. Since forth is a direct connection of the main shaft its pretty hard to mess up its ratio. <img src="/forums/images/graemlins/rodent.gif" alt="" /> That leaves fifth gear as somehow being a direct drive, that seems unlikely.

Ricardo, has it always behaved like this after you purchased it? Did you buy it from a car dealer or the prior owner? Maybe either can tell you what's up with it. As you said, people here perform weird things to their vehicles, i asked the man from who i got the Raider about this 5th gear issue, he told me that he didn't anything on the transmission and that he noticed the issue. My question is, besides this problem being weird, It is possible to get a normal 5th gear like the othe Raiders, i mean, with the normal gear ratio? Should i look for any part specifically? Again, thanks for the attention, it has been a pain in the rear looking for help

To get a handle on this can you run a test?
Drive at 2500 RPM in each gear and tell us what the MPH is.
BTW, how is your clutch, does it slip at all?

My first thought was is the clutch gone... In 4th gear, going up a pretty good hill, stomp the gas and see if the rpms go up faster than the truck speeds up.
Not responsible for advice not taken...

I'll cast my vote in with the camp that says
he is stuck in 4WL. His top speed would indicate
that and his low speed 1st gear shift speed says
the same thing. 4th to 5th in low gear does not
buy you much.

BTW, how is your clutch, does it slip at all? Ok Kevin C. I just made a test. These are the results 1st gear reach 13 mph at 2500 rpm 2nd starts at 2000 rpm and reach 20 mph at 2500 rpm 3rd gear starts at 2000 rpm and reach approximately 31 - 32 mph at 2500 rpm 4th gear starts at 2000 rpm and reach 40 mph at 2500 rpm and bloody 5th gear starts at 2500 rpm and going up. This is the nonexistent change in the RPM that is supposed to exist so the RPM could be a little lowered when shifting to 5th. Btw, the clutch is all ok. I hope this will be useful to you to give me a clue about this. Regards Ricardo

Ricardo, What's the answer to this question? You gave us detailed facts about the other gears but not 5th where you're having a problem!!! <img src="/forums/images/graemlins/ignore.gif" alt="" />
