Jon89le Posted September 2, 2004 Report Share Posted September 2, 2004 For those of you who swapped to the Getrag 282/284s into your W-bodies, what was involved? Im looking to see if it would be cheaper to beef up a 282 for the 3.8 i have as opposed to drop $2500-3000 on an automatic. Thanks for any help/opinions.

94CutlassSLCoupe Posted September 2, 2004 Report Share Posted September 2, 2004 The 282/284 components will bolt right into to all the 1st gen W's without a problem. I would only do this if you have a complete donor car. Your biggest problems are: 1) Transmission Strength 2) Flywheel for the 3.8 (west coast fieros have them) 3) ECU programming I really want to do this swap at some point and use an '88 Cutlass Supreme FE3 Coupe like i used to have Quote Link to comment Share on other sites More sharing options...
Jon89le Posted September 3, 2004 Author Report Share Posted September 3, 2004 Is it possible to strengthen a 282 to hold a good 400lbft? Quote Link to comment Share on other sites More sharing options...
Baddflash Posted September 3, 2004 Report Share Posted September 3, 2004 I'm not sure if there is much you can do to beef up a 282 and a 284 would be pretty expensive if it had problems. I know of the 282 being used on L67's with no problems but in much lighter cars, but it also depends on how you drive it. I guess someone need to be the ginnea pig....go for it and let us know how it turns out... Quote Link to comment Share on other sites More sharing options...
henschman Posted September 4, 2004 Report Share Posted September 4, 2004 dude there are fieros with 400 ftlbs and more with 282s. Just get a pressure plate and cindered iron clutch disk from west coast fiero or wherever else has them and you'll be aight. I don't know where you're looking if the only autos u can find are over $2000... u should be able to find a 4t65ehd or 4t60e for more like 3-500. If youre gonna do a manual id go with the 282 bc parts for the 284 are way expensive if you do break it, and i don't even know if anyone makes aftermarket clutches/pressure plates for them anyway. I'm planning on using a 282 in my fiero, which should have about 400 hp and tq also. Quote Link to comment Share on other sites More sharing options...
GrandPrixGTP95 Posted September 4, 2004 Report Share Posted September 4, 2004 Hey Jon, I'm currently doing this on my 90 GP. Its an SE with a 282, and its being rebuilt and cryodipped, has a spec stage 4 clutch, and I have another tranny that I will be building for the power I expect to see later on. The swap is a bitch....and the car has been down for 2 months....soccrplayrgtp is working on it. Oh BTW...i'm TopendGTP95 over on clubgp.. 8) Quote Link to comment Share on other sites More sharing options...

brianteel Posted September 5, 2004 Report Share Posted September 5, 2004 well i am in the middle of doing a 284 into a 96 GP using lumina parts. I will let you know how it goes i hope to have it close to done by then of the week Quote Link to comment Share on other sites More sharing options...
Jon89le Posted September 7, 2004 Author Report Share Posted September 7, 2004 There is no way you can a stock 4t65-HD with a modified motor and expect it to last. Thats where i was getting the up to 3000 price tag from since thats what it costs to rebuild OR purchase a "bullet proof" trans. People are having tranny issues on otherwise stock 3.8s. I wish the tranny could tho . For those of you who did the cryo-treatment, what did you do and for how much? Brian, The 284 you said you are going to be using, is that for the 3.8? If it is, any reason you used the 284 as opposed to the 282? Quote Link to comment Share on other sites More sharing options...

brianteel Posted September 7, 2004 Report Share Posted September 7, 2004 the only differents between the HD and non HD trans is the differental and lower gearing. everything else is the same Quote Link to comment Share on other sites More sharing options...

If it is, any reason you used the 284 as opposed to the 282? i went with the 284 because the parts car that ihave has that trans in it. I am bolting it up to a L67 with MODS: -L67 Swap- 3.2" MPS, 180* T-stat, RT DP, 2.5" Exhaust, summit turbo mufflers, FWI, ZZP poly mounts, DHP PCM, Intense Stage 1x cam, 105 lbs valve springs, steel retainers. I am using a close to stock clutch so i burn that up before the trans does. I am hoping to have it in and done by the end of next week. it all depends on the rain this Quote Link to comment Share on other sites More sharing options...
Jon89le Posted September 7, 2004 Author Report Share Posted September 7, 2004 Even with the upgraded differential between the -HD and non, i didnt think that would be that much of a difference. The problems people were facing i believe were cluctch issues, loosing gears, etc. The upgrade i was refering to was the -HD upgrade that Intense sells. Brian, let me know on the GP forum how that goes. Quote Link to comment Share on other sites More sharing options...
brianteel Posted September 7, 2004 Report Share Posted September 7, 2004 will do i am tearing apart my car today as long as the rain holds out. the upgrade that intense sells is the input and output shaft and the clutches. the automaticis dont really have gears Quote Link to comment Share on other sites More sharing options...
skalor Posted September 7, 2004 Report Share Posted September 7, 2004 Brian, let me know if you need any help with the 284 swap. I've already done one in my TGP and if you need any suggestions just ask. We meet at the Intense/Dynotech mod day if you don't remember my handle. I asked to see your car and my brother has the 3800 SII S-10. What clutch are you planning on running?? I would go with a SPEC unit as they are the only reasonably priced 284 clutches. I used a stock 284 clutch as I heard from a bunch of sources that they were rated for 300 ft lbs of torque. I also saw that the SPEC stage 1 was rated for 380 ft lbs so I figured that 300 ft lbs was about right for stock. Well, here I am 5 months later with a little over 5,000 miles and it's already slipping. I even babied it for the first 500 miles too.

brianteel Posted September 7, 2004 Report Share Posted September 7, 2004 well i am at the point were i am pulling my dash off. I have not run into anything i could not handle. The only reason i plan on using a stock clutch is because i dont want to blow up the trans right away and i can get it really cheap. I am looking at one that is a 9 3/4 disc compared to the 9 5/8 that most are. the only thing i am looking into what i have to do to the flywheel to make it work. i do remember you. my trans started doing the same thing my last one did so i decided to get rid of all the complcated auto and go manual. I want to try to get it done before next wed but it all depends on the flywheel machining Quote Link to comment Share on other sites More sharing options...
skalor Posted September 7, 2004 Report Share Posted September 7, 2004 I don't recall what the stock 284 clutch disc size is, but I know it's bigger than the 282 disc. I just used a stock clutch that I got at advanced auto for like $197 or something like that. I've heard that all stock 284 clutches are made at the same place, but I don't know if it's true or not. People have compared the Advanced Auto one to the GM one and supposedly they are the same. Just keep in mind that your launch is going to go down the shitter. I ran a 2.1 60' in my TGP when it was auto. The best I've managed the first/only time I took it to the track with the 284 was a 2.398 and that was with 245/50/16 tires. I haven't been back to the track yet, but I think I can get it down with some more practice. Quote Link to comment Share on other sites More sharing options...
