My friend was coming home one night and said that the truck got stuck in gear. Got the truck home, and up on ramps. Shift lever will not budge a bit. Removed the shift lever, and can see that the offset shift lever inside the transmission is in fifth gear. How would I fix this problem?

Hello,

It sounds like something is broken inside the transmission it will need to be taking apart to see what happened.

Here is a guide to help you see what you are in for when taking the transmission out:

Check out the diagrams (below).

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken

I drained the trans, since apparently the fluid had never been changed. Of course some gray sludge at the bottom, including where the offset lever is on the shift plate. Will a refill with fresh fluid fix anything (I'm doubtful)? I think I am gonna try to rebuild it, sounds like a great learning experience. Are there any guides for rebuilding this one? Its the only 5-speed manuals they put in these.

Here is a full parts explosion and step by step to rebuild the transmission,

Remove idler shaft support bolt (311) and bottom two bolts. Refer to Figs. 1 through 4 to aid in disassembly and assembly of transmission.
Install holding fixture tools as shown in Fig. 5.
Remove back-up lamp switch assembly.
Remove bolt (317) and electronic speed sensor assembly (314) (2WD models only).
Remove detent plug (245) using plug remover tool No. J-36509 and No. J-23907 or equivalents, then remove spring (244) and plunger (243).
Remove two bolts (236), detent spring cover (325), springs (324) and balls (323).
Remove output shaft oil seal (320) on 4WD models using seal remover tool No. J-36825 and No. J-23907 or equivalents. Screw No. J-36825 into one of three perforated holes in seal.
Position unit vertically and remove six bolts (204) and input shaft retainer assembly (205). Save input bearing retainer washer (208).
Remove selective snap ring (210), input shaft spacer (211), ball bearing inner race (215) and shim (212), then position horizontally.
Remove front housing to rear housing bolts (312) and drive dowels (321) from front housing, then remove front housing (200).
Remove countershaft bearing (203).
Remove ball bearing inner race (217) and roller bearing (218).
Remove idler shaft support (310) and four rollers (118), then remove roll pin (120) by pulling shift shaft forward and cocking it to detent cover side. Support shift shaft end while driving out finger roll pin. Slide shaft all the way back and cock over to detent spring cover side.
Remove shift shaft socket assembly roll pin (122). Pin will fall into case. Do not use excessive force as this will "peen" the shift shaft and damage rear housing shift shaft bearing, causing increased shift effort.
Remove shift shaft (116), shift shaft socket assembly (123) and finger (121).
Remove 3rd and 4th shift fork roll pin (107) using large pair of diagonal cutters to pry it out. If roll pin (107) breaks off, place transmission in 3rd gear, cut off remainder of roll pin and drive through.
Remove plug (326) by hitting it on one side, thus cocking it.
Remove 3rd & 4th rail (109) as follows:
Ensure 1-2 and 5-reverse rails are in neutral.
Drive through the plug hole (326) enough to expose roll pin hole (107), then insert punch and pull out shift rail while twisting it.

Please let us know what you find. We are interested to see what it is.

So the drain and fill actually got the lever unstuck, but of course it is extremely hard to shift. I am suspecting a broken shift lever/pad. This is a T5 manual transmission, and the Haynes manual says that I can take out the transmission and leave the bell housing on the vehicle. Is this so? Also, it says nothing about draining the engine oil, should I?

Yes you can leave the bell housing but I would take it off so you can inspect or replace the clutch which makes the transmission work much better. Yes drain the oil, also check the pilot bearing here are guides to help you see what you are in for when doing the job.

So I got the trans out and partially apart. Unfortunately the best case scenario didn't happen, that is having the shift forks broken and only replacing the shift forks. Now I need some help determining the real problem here. The first video I have is spinning the gears and looking closely at them, they look somewhat worn and you can hear the deep sound the gears make when spun. I took off the retainer for the input shaft. The second video shows how loose the input shaft was, and right after that video it just fell off. Maybe the problem is here? The needle bearings (pictured) look kind of beat up, and the shim (pictured) is also bent. I'm open to thoughts and willing to take any pictures.

Fantastic great videos and pics, it looks like you will nee to replace some bearings which will require a press.

You have all the diagrams to get the transmission apart above in this post. Please take a video telling me what the problem is and we will rebuild it step by step.

The problem was the shift lever being stuck after getting the vehicle stuck in the snow. Could worn bearings cause that? I see that most rebuild kits for this actually only come with bearings, synchro rings, and shims (maybe). The gears look okay (I guess) from what I can tell.

So, the input shaft is supposed to fall apart like that? Or does the problem stop at the bent shim? I know that since the trans is apart it's easy to say "go ahead" and replace everything, but I'll have to go buy the cheap 7-ton (or 10) press from Harbor Freight if that's the case.

The input shaft has the bearings inside it and it just slides over the output shaft stub. The shaft is held in place by the bearings on that shaft and the larger tapered bearing that rides in the stub that is bolted to the face of the transmission. The bearings prevent them from turning together but you are going to need to inspect the bearing races machined in the input shaft and on the output shaft very close. Those bearing rollers show signs of water and rust damage. That will easily chew up the races as well.

Being stuck in gear can easily be caused by worn bearings as it allows the shafts to move in relation to each other and if a hand or? Was to hit the shifter at the right moment it could jam the gear into the teeth enough to cause it to stick.

I would price out the kit and any other needed parts (possibly the input and output shafts if they are worn).

I found a rebuild kit under $100.00 that would replace only bearings, racers, snap rings, gaskets, etc. But no gears, pins, springs, forks, etc. That would be sufficient?

That is what most manual transmission kits contain. Then if you needed a different part like a shift fork or an input shaft you buy those as needed because they do not normally need to be replaced.
If they included all the internal parts that could be worn or bad you would be buying a remanufactured transmission, not a rebuild kit.

That is why you go through and examine each part and measure for wear. The rebuild manual on that transmission will give you the measurements, wear points and good/not good numbers for each part.
In 99% of the rebuilds you replace any bearings, gaskets, seals, syncro rings, snap rings, and shims so you can do the job.

One item I do not see on your list is replacing the clutch itself. Unless it has been changed within the past twenty to thirty thousand miles, now is the time to do it as well as the transmission is already out. But that is your choice.

Actually the clutch was replaced not too long ago, so it is good. Also, I think I just realized that those bearings in my hand were those that fell out of a worn bearing? Feels like a stupid question.

Are there any recommendations on an affordable press that I can put the shaft on and do the work? Or a way to do it without a press? Harbor freight has an H-frame that looks tall enough.

Yes, those were most likely the ones that go inside the input shaft and ride on the tip of the output shaft. See item 3 in this picture. When you go to assemble them you coat the inside of the input shaft with grease, place them in there around the bore and slide the two parts together. The grease holds them in place and will dissolve in the lube.

Press wise, it depends on which bearings you are working with. Some will almost fall off, other will make you want a bottle of tequila and a torch! That is one of the "fun" parts of auto repair. I have three presses, a small modified HF 6 ton bench unit, an old 20 ton Dake and a 75 ton Atlas that I think came here on the Mayflower LOL.
There are days that all three get used, on the same part !

If you doubt you will ever use one again (might be surprised as they can do quite a bit) you might look and see if there is a shop around you that would press things apart and put them back together. Not sure if it would be cheaper but it is a solution.

So I got the counter shaft done, no bearings left on that and now I am wondering how to press off the synchros on the output shaft. Also, this transmission has a silver speedometer gear, do I press that off? There are no clips holding it on.

The gear has to come off. Basically half of the pieces come off one end of the shaft and the others come off the opposite end.

It should press off. Do not pound on anything in that transmission unless you want to replace broken parts. BTDT.

So I managed to get the first gear cluster off (third gear I think) and I find that it was so difficult because the fiber part on the synchro was practically glued to the gear. Does this mean the transmission got to hot when they tried to drive it out of the snow? Also the needle rollers were all bunched up. Do I need to get a set of synchros? Where could I find more needle rollers?

Let me know some thoughts.
