lost 5th gear
 

Ok ever scince i had 93fd (no mods) she has made a little grinding sound when I shift into 5th gear. Now I can not shift into 5th at all. I'ts like the gear isnt even there. I still have 1st, 2nd, 3rd, 4th, and reverse. It doesn't make the grinding sound anymore when i try either. Has anyone else had this problem?

That broken 5th synchro is now out of position and blocking the clutch sleeve from engaging the gear. Make sure to have a new 5/R clutch sleeve on hand as well as 5 synchro when you have it fixed.

^damn I love reading your posts about tranny's...I learn so much. I guess until I tear one down, they will flabbergast me, haha.

Haha, nobody knows if I'm full of shit though :)

Hey Dave,.. Can you replace the parts you listed without having to tear the tranny completly apart? Do you just remove the rear housing? Or complete tear down. Thanks. I would like to take care of this over the winter.

Any odd speacial tools needed? That only Mazda makes;)

Damn! Got a link to his write up?

well I've read your write up...and you've offer to rent the tools, etc...

^been stamped off

For 5th clutch sleeve and synchro, you only need a big socket (1-1/4"?) to remove the countershaft nut, and a set of extensions to make an extra-long 2-jaw puller. I also had to grind the ends of the puller a bit since they didn't quite fit under the edges of one of the bearings. For a complete rebuild you'll need some more bearing pullers, a press, and a super-deep socket or some other socket for the mainshaft locknut.

5th synchro is not a complete teardown - just need to remove the extension housing, rear bearing plate, and 5/r housing. I've heard it can be done on the car, but I've never tried it. I just stand the tranny clutch side down and work down.

My writeup is at www.davidgeesaman.com - but there are some other writeups linked in the FAQ that cover just 5th synchro more concisely.

So how much would a shop charge me? aprox. I dont have tools otherwise id do it myself.

I dunno - $500? Call a rotary shop and tell them you need a 5th synchro job.
