i am gonna buy a 85 z28 5 speed (i hope it's a z lol) anyway this will be my fisrt 5 speed so i don't know much about the transmissions like what came in them and how good are they. also what rears came in the 85 z 5 speed because i have an 85 z with 3:73's it had 3:08's in them and it's a 2 series carrier so i wanna know if the 3:73 will fit in the 5 speed.

thanks

 

According to the tech data, an '85 Z28 LG4 5-speed would have 3.23 gears, so 2-series gears would not fit that carrier.

Why not just change out the entire rear assembly?

 

thanks the reason i ask is beacuse i just put new gears in about a month ago and i found out that my axles spider gears and carrier are bad so i wanted to just swap gears into the 5 speed or i can swap rears and replace the axles and put a posi unit in im not sure yet

 

You can get a posi carrier that will fit both your 2-series gears and 26-spline axles. About $300-$350 plus installation labor, perhaps install kit (another $100 or so).

What's wrong with the carrier? A PowerTrax unit will install in a non-posi carrier and eliminate the spider gears. It's also about $325, but the nice part is you can install it yourself without any special tools. Of course, if the spider gears wiped out the carrier, that won't help you any.

Oh, your 5-speed question: They can't handle a bunch of abuse, but guys that take care of them and know how to shift are running 13's in their cars with them. That's respectable.

 

i dunno what's wrong with the carrier. i had the gears put in and the mechanic told my about the axles,spider gears and the carrier. honestly i dunno what the carrier is. what happens if it goes bad?

 

The carrier is basically a hunk of metal the holds the ring gear, spider gears, and is supported itself in the housing by roller bearings. About all that could go wrong with it is excessive wear on the surfaces on which the spider gears run. Or, less likely, where the bearings are supported.

 

im gonna try and take out the 3:73's the toss the rear and just start over again on the red one . im picking it up tonight.
