i plan on buying the above, figure while im doin gear change why not change all the bearings and crap, thing is, my car is 2.73, it was an auto, swapped, and it says on jegs "for 3.23 and numerically higher carriers" id hate to get this and get my car torn all apart for it not to fit, also, i already know the answer to this, i believe i need a new master/slave, i never lose pressure but sometimes when i push the clutch in from a stop i cant get it out of gear without yanking it out. i only got 300 to spend, i want to get the tick adjustable, since the 4.10s will require me to shift almost double the amount of times compared to 2.73s i think it may be cheaper in the long run to get the master slave first because i dont want to **** up my transmission.

Oh and by the way! before i did the a4 to t56 swap i read everywhere 2.73s were gonna suck, it definetly does not! lol not bad at all actually, although i cant use 6th till at least 70mph lol

BALLSS

you need a series 3 carrier (rear end) for the 4:10's

you read wrong on the 2:73 & T56 being a good combo...3"73 are "OK"...4:10 ideal.

$300 won't get you where you need to be for gears...fix the MC

FWIW you can just buy a stock MC unless you feel you need a ajustable

Bengtson95

Okay that's too bad, and I was looking at the tick because I have another motor I'm going to bore and stroke and b pushing quite a bit more hp, and no I read it wasn't a good setup with 2.73s but I don't think it's half bad, 1st and 6th suck lol but thats all, anyone running tick master slave how is shifting different? I have mgw short throw and it's not as smooth of a shift, sometimes grinds, mostly just harder to get into gear, gotta Rev match often, is that a master slave problem or syncro problem?

BALLSS

you may have a hydraulic problem if hard to get in gear.

jack car up in rear and put on jack stands. Start car with tranny in 1st & clutch all the way in...do the rear tires move?

if yes you have a disengagement issue because of failing hydraulics (MC or slave but MC more likely)

I use the McLeod MC (Wilwood). It and the Tick that have a adjustable rod alllow you to extend it slightly if you need more stroke for full disengagement.

wiith that said for single disc clutches a stock MC/slave should work fine. You can buy a MC/Slave pre-bleed for around $125. If it is the 20 year old original...likely tired

Bengtson95

Not sure how old the master is, off the doner car, but yes my clutch doesn't fully disengage, I don't want to spend 300 on the tick but I will b putting alot of power into the car so I might as well...they are warrantied for life

Bengtson95

Another question I had my doner car had a 3.43 gear ratio can I take the rear end out of that one and eventually put 4.10 in it

BALLSS

yes...

BALLSS

did you transfer the donor hydraulics as a sealed unit or detach the braided line and install the MC & slave separate?

if so you may just need to bleed the hydraulics better.

is the plastic cup still on the slave rod tip?

Bengtson95

Transfered as a complete unit, it's been like this for quite a while, 5+ months, and my question about the rear end I meant can I swap 4.10s in it without buying a series 3 carrier is what I mean. Lol I know I can put 4.10s in mine just more $$

BALLSS

if you use the donor rear end (complete unit) that has the 3:42's you can put 4:10's in that. It is a series 3. You need to swap in the whole rear end from donor car

Bengtson95

Okay yeah that's what I was thinkin, guess I'll have to contact the guy I sold it to, he's using the shell to build a pro stock car with 800+ horsepower, so I'm gonna guess he's not going to use the 10 bolt lmao

You can certainly put gears made for 2-series carrier in a 2-series carrier. like this:

sometimes you might want to put perfectly good on-hand 3-series gears in a car with a 2-series carrier. In that case, you'd need a spacer to make up the thickness of the ring gear. Like this:

Bengtson95

Ahh okay I didn't know you could do that, I may do that in the future, although, is there any difference in th carriers? Is one stronger than the other, I'm guessing since the adapter is to makeup for thickness I'm guessing series 3 carrier has thicker gears then mine? Hence they would b stronger than mine? This is out of my relm, havent messed with differentials thanks for all the help

BALLSS

^^^ I didn't know they made 4:10's for 2 series 7.5" GM 10 bolt

are these gears "thinner" than ones for a series 3?

It appears OP's post link of the JEGS gears they are for series 3 carrier based on the min gear set they are replacing are 3:23

I didn't know either, but it's been a while since I looked. I have a 94 M6 car with 3.42s in its factory 3-series (3 channel ABS) rear and have another 94 A4 car with 2.73s in its factory 2-series (also 3 channel ABS) rear. I bought 4.10s for the M6 and was planning to install the 3.42s with a spacer in the A4. Most people with stock-ish A4 cars are happy with the 3.23s in most A4 cars so I thought a touch higher with 3.42s would be a good fit. Now that I see there are indeed 4.10s for 2-series carriers, I might consider 2-series 3.73s for it. I'm cheap, so I thought I'd do my best to use what I have.

2-series ring gears are thicker than 3-series. The higher the numeric number, the more teeth on the ring gear and the more potentially fragile the ring gear becomes because more material is removed from the ring to make teeth. I'd think that a 2-series 4.10 ring gear would be stronger than a 3-series 4.10 ring gear, but I'd need to look at them side by side. Maybe on a 2-series set, the pinion teeth are longer and the ring gear teeth are deeper, negating any gain in apparent strength from starting out as a thicker piece before machining the teeth.

Here is my advice, on a T56 car and a 10 bolt don't do the 4.10 gears. I've been there and done that, even after having them mikronited I killed a set of 4.10s after a trip to the track on street tires...

Save up and do it right, once. If going to a 4.xx gear get at a minimum a 12 bolt... My Moser 12 bolt has held up well with 4.11 gears.
