Worn Synchro's
 
How much would it cost to replace worn synchros? I am sure that the synchros on my cars are fucked and I need to replace them...*sob*

I would assume that would be none to cheap...

Why dont you try cheaper alternatives like a new bushing kit, or switching to REDLINE synthetic Gear Oil... that will help like crazy...

A fluid change might be all you need...I don't think all the synchros would go at once. The parts are really cheap...it's the labor that will kill you. It's normally around $350 just to take a tranny out of a car and take it apart. (maybe that's just in FWD. My MX-7 tranny was the only one I ever had rebuilt) Like Rx7-88na said, be sure to use redline fluids. I've heard the most success stories about it.

or
 
go to a junkyard and get a turbo2 trans for acouple dollars and do it your self, or have installed with red line fluids i blew my N/A trans up at atco lettin the clutch go at 9k rpm's and gettin too much traction... then i did a T2 trans swap, got a flywheel, clutch and trans and swapped it all in myself and never had ne problems again, then i totalled it... :( stupid drunk drivers

and to rebuild its gona cost over a grand to do...

Red Line
 
I switched over to Red Line transmission fluid. Made a noticeable difference right away. My 3rd gear synchro was the worst, and after switching I could downshift into 3rd without making terrible noises.

After a week or so I noticed that everything got even smoother, not perfect or anything, but definetly much better in all gears.

Highly recomended

redline
 
ive heard that sometimes redline has actually mad the situation worse because its just to slick. is this wrong?

TristanTII 11-29-01 05:47 PM

Mobil 1
 
the only complaints I've heard about being too slick is from Mobil 1, or similar. Red Line advertises that has balanced viscousity or something.

to change you need like 4 quarts of the stuff, and a pump to get it in. all and all it probably costs less the $40, depending on where you get your oil from. And takes an hour, maybe.

very worthwhile

where can I get Redline then?

Rx7-88na 11-30-01 01:34 AM

You can get Redline Gear Oil from summitracing.com it cost about 8 bux a quart... your tranny is 2.6 quarts capacity so you need to buy three quarts, and... its MT-90 Redling Gear Oil..

I hope that helps...
