Engine/Transmission (1998.5 - 2002) How hard to replace 5th gear shaft??

[Turboman]

Can anyone tell me how difficult it is to replace the 5th gear shaft? Is this the only way to fix thr 5th gear falloff? I am going to help my bro-in-law replace his clutch over Christmas and since he has had the nut fall off twice we are going to fix it right. Is it a major job to do this? Any advice would be greatly appreciated.

I would like to know also......

I was going to try the "upgraded "nut fix, but I don't want to just be wasting my time. I do not need to have the transmission out for any other reason at this time. My Fifth gear nut has not failed yet, but ..... when, one never knows.

Changing the mainshaft involves almost complete disassembly of the trans. See TDR #31, pp. 23-27

I just got through replacing one in a 98. I wouldn't say it was really difficult because I did it but it does require a couple special tools and a service manual is very helpful.



Basically you have to disassemble most of the transmission because this is the "mainshaft" your replacing here. I put new bearings and syncros in the one I did because I was there and it had 100k on it. Not knowing really what I was doing it took me about 12 hours.



I bought my parts from Standard Transmission and Gear and was happy with their stuff. The new mainshaft had a groove cut around it with a pair of locking keys and a ring to hold them in. I don't see any way that gear is gunna slide off now. Hope this helps.
