Toyota E153 transmission swap

[SgtRauksauff]

On my SPEC stage3 6-puck in my wagon, I babied that car for the first 500 miles, even getting 35mpg for two tanks in a row!! I never launched it hard, and tried not to slip it too much. Reverse chattered like a mofo for awhile, until I got used to the nearly binary nature of the clutch. It did take a day or two of playing around with it to get it to take off nice.

super rock-solid through the rest of its life. After about 3 years, when the tranny was out because of a busted speedo gear, I checked it, and the friction surface was almost to the rivets. So, I tossed in a used SPEC stage3 clutch, but one with a solid disc, and that started slipping soon after.

You should be fine, provided you don't get too much heat into the flywheel or friction surface.

jon, do you have a full face on this application again or not? 6-pucks i don't have much faith in to begin with

[therieldeal]

it is a custom 6 puck disc and an 1800# pressure plate. when i said mazda pressure plate i was just stating the application, not that it was OEM!

i was going to go full faced again but spec wanted $300 for just the disc. they are also the only ones who make it. the last one ate up my flywheel and pressure plate to unusable condition in only 3000 miles, so for that kind of money i decided to try going a different route.

i guess i'll keep babying it, we'll see what happens

The guy that did my fab work is a VERY experienced drag racer. I asked him about break-in on my clutch, and he said there's no need to break one in like you ould on an organic clutch. I've been driving it the same way since install, 15,000 miles ago, and everything's still perfect.

[therieldeal]

well then wtf :/

[Hadoken]

Everything I've heard about puck clutches leads toward them not needing a break in period. They are race clutches so it's not like people are babying their race cars up and down the street for 500 miles before going to the track.

its most likely the pressure plate or as stated above possibly there is slight pressure on the fingers when the clutch is released not allowing the clutch to grab 100% take the slave off and see if the fork moves if it does you know your sitting too close on the fingers. then just shim back the slave.

[Darryl]

dont shim back the slave cos it will automaticly adjust back up then if its loading the slave up its cos there isnt enough free play in the master

[therieldeal]

there is no tension on the clutch fork with the clutch released

i put my .6 bar spring back in the Tial, and it holds that much boost (~9 psi). i'm just going to keep driving it for a few hundred more miles then i'll swap the 1 bar spring back in. if it holds that then i'll hook up my boost controller.

Does the car feel any differently with the new tranny? Congrats on getting this done!

[therieldeal]

the depowered steering feels heavier than i remember, it has been nearly a year though. it could be the extra weight, extra track width, or my imagination.

there is a LOT of vibration because of the nearly solid mounts. the entire shell of the car resonates at high rpm.

[MD323]

There is no break in period on a puck clutch but with any friction surface there is a bedding perio in wich all 3 surfaces will slip alittle while wearing down any highspots. You should drive it how you you plan to drive the. Car normally and just let off when it slips some and then get back on it

Btw who and how much was that clutch? A sprung 6 puck would be nice for my setup

[therieldeal]

the clutch was very reasonably priced, so much so that i'd probably have been willing to pay about 2x the price. however if i HAD spent that much, i would be even more pissed right now.

its still holding the 9 psi fine. i'm going to take it a couple hundred more miles and then try upping the boost.

passed emissions this morning on the 625cc injectors and 2.5 year old high flow cat

btw i'm moving this back to work logs i'll make a smaller more coherant thread to sticky over in drivetrain swaps
