Bake82 Posted March 31, 2023 Report Posted March 31, 2023 (edited) Hello i am possibly swapping a getrag 284 into my car, and curious what people are doing for clutch hydraulics. Rockauto lists both a master and a slave but no inventory. I know the clutches and TOB are different and the push vs pull However the slave cylinder is always pushing out The lever it connects to inside the transmission is just different in their action to engage the clutch I have a known hood setup from a 282. They look almost indentical (minus the vacuum ball in the hydraulic line). has anyone tried 282 parts? If not, anyone have a source for them? thanks!

GTP091 Posted March 31, 2023 Report Posted March 31, 2023 I bought what they had a few years ago and it wasn’t much, I don’t think it was the last but was a final clearout. The slaves were available back then. I can’t say if the 282 master would work for the 284 slave. I’m pretty sure you’ll need a 284 slave. They used to be easier to come by. Assume you’ve sourced the 284 already. Can you still get the rest of the parts? Also think you’ll need the stub shaft for a 284 as well? Quote

(Just realizing this). I’ll keep looking to source as well! Hoping they can stil be found Go4DaMo 1 Quote
GTP091 Posted March 31, 2023 Report Posted March 31, 2023 I just checked RA they have the slave listed. https://www.rockauto.com/en/parts/fte,3100032,clutch+slave+cylinder,2044 and on clearout. https://www.rockauto.com/en/parts/luk,LSC114,clutch+slave+cylinder,2044 you can skip the accumulator as well. Just need the master and the reservoir then. Bake82 1 Quote
Bake82 Posted March 31, 2023 Author Report Posted March 31, 2023 What I find interesting, and I guess I didn't explain why I was skeptical on these Slave cylinders. The cars they list for are 88-93 w-bodies, along with J-body and N-body, which would be getrag 282's only. There is a separate listing which lists for 91-93 only and those are the ones I was thinking were actually 284. But also, why I am thinking maybe they are the same as the separate part# includes the hydraulic hose, which I know was 284 specific. So maybe the only difference is the hydraulic line/vacuum ball think. Quote
carkhz316 Posted April 2, 2023 Report Posted April 2, 2023 You can use the 282 master for a 284 transmission. The only difference is the size of the internal piston. I can't remember if its smaller or larger, but it'll only make for a slightly shorter or longer pedal throw. SuperBuick and Go4DaMo 1 1 Quote

Thank you!!!! I know they physically look the same but figured the internal bore may be a bit different and wasn’t sure what the affect would be! wonder if the slave would be similar situation. And how it would al work together! Go4DaMo 1 Quote
White93z34 Posted April 5, 2023 Report Posted April 5, 2023 yeah I know the bore sizes are different but other then that I can't say. I know back in 2017 when we Converted Matt's GTP (your old one I believe) to 284 we eliminated the dumb accumulator and used a braided hose Go4DaMo 1 Quote
Mach 5 Posted May 26, 2023 Report Posted May 26, 2023 wow thats crazy i had to look in to this. been out of the w-body world for a few years now crazy to find parts are unavailable. the 284 master is larger bore but same slave between both 282-284 trans. so with a 282 master the pedal would be softer and pedal release height lower. I guess knowing this now.. Im going to have to figure out a replacement solution to fix this issue. maybe fab an adapter for a 2 bolt setup something more common and universal. right now im running the 282 master with a braided line to an internal slave setup 284 trans twin disc with pedal limiter. maybe we can make a aluminum adapter that screws in to the firewall? gotta keep these dubya bodys alive!! also. i heard Rodney Dickman is shutting down and selling the business.. crazy! good luck ion your search. ill ask around see if I can find any parts. -Jarek Go4DaMo 1 Quote

White93z34 Posted December 2 Report Posted December 2 theres a thread somewhere here with the part numbers from Summit, we used whatever that was. works good. Go4DaMo 1 Quote

I’m going to talk to the fab guys at my race shop and get their thoughts… @Bake82 I might need another firewall plate temporarily if you have one!!! :-) Go4DaMo 1 Quote
