box transmission

A common complaint is inability to find reverse and fifth gear easily. I had that problem with the Fatrat yesterday (both gears were accessible with this gearbox in the rat). I worked the shifter all the way to the right looking for reasons I couldn't find those two gears and heard a...

These are the numbers for bearings used in the 5 speed transaxle. They can be found on line (eBay-etc) or from the local industrial bearing supplier. Nothing special about these bearings as they are used in many other oily bits. Suggest known quality brands like SKF, Koyo, NTN, NSK and similar...

Working on the "dog bed" as my wife puts it (as in it's the same size lol).....clutch and brake hydraulics at the moment replacing pretty much everything from the reservoir on down for the brakes and clutch...new masters (and slave for the clutch)......new hose.....everything going well.... I...

About 7 years ago when I did my carb to FI conversion on my '79, since I had the whole drive train out, I decided to take apart the transmission to get rid of the 2nd to 3rd upshift crunch. I used the "5 speed 101" instructions to disassemble and reassemble and it all seemed to go well. It's...

I know this topic has been beat to death over the years so if someone can point me to the best previous discussion on this I'd appreciate it. I had a real honest to god old time Fiat mechanic rebuild the gear box and all the other gears work great so I'm assuming it's a linkage adjustment issue...

Seeing the new thread reminded me I've been meaning to post about my concern - my clutch engages with the pedal very close to the floor. I have in the past replaced the slave / hydraulic line / rod & the actual clutch, and the pivot bushing in the bell housing. I don't recall if it has always...

Not much magic or special about the shift forks in this gear box, except to check for wear at the ends of the fork. They are usually OK unless worn. The forks appear to be made of brass except they are magnetic. Not sure precisely what they are made of, could be a brass alloy with iron or...

The input gear set and Pinion gear set from a 1979 transaxle. The reverse gear on the input gear set. This often gets chipped, worn and abused as previous owners and abuser crash the shifter into reverse gear. If this gear is excessively chipped or damaged, the entire input gear set will need...

Inspect the crown gear on the diff housing for excessive wear, broken teeth and any other visual defects. Inspect the spider gears and their spherical bearing surface. The spider gears can be rotated within he diff carrier to inspect them. Also check for excessive spider gear backlash. On a...

This 1979 5 speed transaxle arrived from a friend's race car with the innards needing attention. Part one shows how to take one of these apart. Transaxle on the bench ready to be worked on. Un do the two M6x25mm long bolts using a 10mm wrench holding the input shaft sleeve which the clutch...

These can be a real problem to install. https://www.youtube.com/watch?v=f-Tn90QAayc&list=UUwh_UaR9_fgy97tZynvKs-w Bernice

Some time ago there was a discussion of how to improve the feel of the shifter on the exxe with the compliant shift coupler aka, lollipop. Mark Plaia mentioned drilling a hole thru the center of the coupler and add a bolt with a self locking nut. This allows adjusting the compression of the...

I was thinking it might be useful for everyone if you could post the installation instructions for the shift rod seal and speedo drive here. What do you think?:)
