you can change your transmission fluid :-P.

talk with 4DoorGTS, hes on the Club4AG Forum as well. He was telling me that you can use different shift linkage bushings and get a smoother feel on the stick, i honestly cant remember what exactly he was saying, but i would try and talk with him.

This was for the AE92 Coupe, not sure if it applies to all AE92's or not.

Is it a C52 tranny?

If so, I would replace the bearings to prevent the common '5th-gear-pop-out-problem' known with the C52

For an even smoother feel, you could even replace the synchromesh rings...but by then you're already looking at a total rebuilt

he might have been talking about the metal bushings speed source sells

I'm probbaly gonna just do a rebuild I did change the trans fluid with Royal Purple though and felt a big differnce but the 5th gear does pop out when I play with the gas a little

cEtnA · 08-12-2009, 04:36 PM

synchromesh ring? what's that and what does it do? also another question I had was since my car is pretty much 20 years old and it seems to have all the original parts..... (even what seems to be the very first airfilter) just bought it would changeing my engine mounts do anything for me? they seem pretty beat that's why

Donald · 08-12-2009, 08:09 PM

I would at least replace the rear engine/gearbox mount. Just because it is so hard to replace with the engine in place. The others I would replace if it is in your budget.

Why are you going with a stage 1 clutch? Do you plan on racing? any power mods to the engine?

Why I ask, is that some performance clutches can be a bit grabby, causing the car to shudder when moving off, unless you have the RPMs high. Ok for racing, but not pleasant for driving around town.
If you do go with a performance clutch, make sure you get one with damper springs in the disk.

I plan to boost down the line so I'm working backwards like upping the trans and engine internals is a stage one over kill for street? what do you recommend?

eage8 · 08-12-2009, 09:03 PM

a spec stage 1? they're the only ones I know of that measure clutches in "stages"

no, that's fine for street.

anything with a sprung street disc will be fine.

I have an ACT in my FC that's good up until 443 ft lbs and it's fine to drive on the street albeit a little heavy... (it has a sprung street disc)

syncromesh = syncros

it's what brings your transmission output shaft up or down in speed to match the speed of the input shaft before engaging the next gear.

RobMilkshakes · 08-12-2009, 10:16 PM

a synchro is the rings in front of the gears that match(.... or sychronize) the lay shaft (connected to the engine side of the tranny) and the output shaft( connected to the differential) since when changing gears, mainly in a downshift or a fast upshift, the shafts are spinning at greatly different speeds, if not the same speed when you go to put the car into gear it will grind.

These tend to get worn out over time, ask my third gear.....

if for some reason they do get worn to the point to where they grind they can be remidied by double clutching like I have to for 3rd. when you double clutch the lay shaft gets sped up so that when you put it into gear the shafts are closer in speed. Cars back in the day didn't have synchros, and large trucks still dont because of the amount of gears in trucks and I'm guessing they'd probably get shredded quickly under those types of loads.

Sadly to get at these you'd have to crack into the transmission which either takes lots of special tools and knowledge, or lots of labor time for someone who does have those. also rebuild kits with synchros can get pricey, I think autozone wanted about $800 for a rebuild kit for my S53 transmission.

Blof-fan · 08-13-2009, 09:57 AM

And RobMilkshakes wins the refrigerator!

The synchro's make shifting from one gear to another, smoother without grinding noises

I rebuilt my gearbox myself and if you do a full rebuilt, it can get expensive.
But on the other hand. If you plan to drive or tune the car...you'll have a gearbox that's as good as new and that can handle a lot of abuse for years to come!

And while the tranny is open...why not put in an LSD while you're at it? Does a lot of good for the handling!

But like said before: It's expensive and it should be done by a specialist. It's not a DIY for most people

Donald · 08-13-2009, 11:55 AM

Yeah! If you are planning on boost, a stage 1 clutch will be a good idea. Just make sure you get a disk with damper springs.
