timg Posted June 2, 2003 Report Posted June 2, 2003 I'm sure most of you have seen the pics of my turbo setup. To make a long story short, my tranny's definitely not happy. It seems that a complete 284 setup will run me $1500 locally and a 282 setup is only $350 for everything! Would this tranny be able to handle 300+ hp and shifting at 7k rpm? If it will, but not for long, is it rebuildable and for how much $$$? Are there any differences between a 282 and a 284 swap? The only built 4T60E's are about $3k! Tim Quote
Redfox340 Posted June 3, 2003 Report Posted June 3, 2003 Oh yeah, the Getrag 282 will hold. Some of the Fiero guys with 5.7L V8's are using them and haven't had a problem. There's been a few posts about this and the 282 is the better choice due to parts, compadibility, and of course the downright fun factor. You should have no problem holding the power. The concern you may have is that doesn't the PCM for the OBDII run the automatic transmission? If so, will 'getting rid' of those sensors or no signal input effect performance or give a Service Engine Light? Perhaps someone has an answer for that! - RedFox340 Quote
patgizz Posted June 3, 2003 Report Posted June 3, 2003 i wish i could find a 282 with everything for 350. Quote
89oldscutlass Posted June 3, 2003 Report Posted June 3, 2003 The guys using them in thier fieros and bolting up 350s to them arent they still having to buy that adapter for their bellhowsing on thier tranny.I looked at the v8 adapter kits from V8-Archie.com Quote
Guest TurboSedan Posted June 3, 2003 Report Posted June 3, 2003 and a 282 setup is only $350 for everything! Tim where 'ya getting the Getrag 282 from? btw, i'm in Gillette today and tomarrow - i'll keep my eye out for your car. joshua Quote
timg Posted June 3, 2003 Author Report Posted June 3, 2003 The car's only OBD 1 so there's very rudimentary tranny control from what I can tell. It shouldn't be too hard to make it work with a manual, though I could be really wrong about that. I'd need to do a lot more research into it before I'd have any idea. Right now I was just wondering if it was even a viable option. Tim Quote
brian89gp Posted June 3, 2003 Report Posted June 3, 2003 A manual on a ECM that thinks its an auto will probably lead to some stalling and other bizzar problems. So, what did you do and how bad is your trans now? Quote
timg Posted June 3, 2003 Author Report Posted June 3, 2003 Ever since I got my intake and exhaust on, 2 or 3 years ago, my tranny has slipped sometimes shifting from 1st to 2nd. I found out that I'd gained maybe 25 hp at redline and I guess it just didn't like that. It would try shifting and take a few seconds to complete she shift and it seemed like it would lower speed halfway, pause, and then go all the way down to where it should have been. Now with the turbo, either it goes into 2nd, or it completely misses and bounces off the rev limiter. I've been lifting between 1 and 2 to try to extend my tranny life. It's working if I only use 3/4 or 1/2 throttle when it tries shifting. Something I've heard is that a lot of w-body computers have a manual tranny flag in the automatic ECU code even if that motor was never offered with a manual. I'd be very interested in seeing if the 94-95 ecu did, but I'm not sure who could find it. Tim Quote
SmokesGTP Posted June 3, 2003 Report Posted June 3, 2003 Couldn't you use an older computer from a 5-speed DOHC? Although they were MPFI and the 94+ are SFI, that might mess stuff up a little. It would probly be hard to find one too. Quote
Guest TurboSedan Posted June 3, 2003 Report Posted June 3, 2003 you probably already know this Tim, but you are going to have a helluva problem getting the clutch pedal mounted since your car was made after '93.... just something to consider. actually i think that's the reason brian89gp sold me his Getrag 282. joshua Quote
brian89gp Posted June 3, 2003 Report Posted June 3, 2003 Yep, a smaller brake booster is needed as well as tearing apart the dash to put the 88-93 style clutch pedal mount bracket. Quote
LukeZ34 Posted June 3, 2003 Report Posted June 3, 2003 But it can be done.. Someone on clubgp (and I think their registered here too) did a 284 swap on his 94 (i think) GTP.. Quote
timg Posted June 3, 2003 Author Report Posted June 3, 2003 Yep, a smaller brake booster is needed as well as tearing apart the dash to put the 88-93 style clutch pedal mount bracket. That's not that bad. I saw the pics on club gp about the swap and how the clutch and brake pedals used the same style frame/bracket on both the MT and AT cars. I figured that wouldn't be much of a problem. I think the biggest problems would be the braking system, the computer, and the center console. Tim Quote
midstar Posted June 5, 2003 Report Posted June 5, 2003 I have a 96 GTP with a 282 5 speed, just got done with it about 3 weeks ago. I have just about all the problems lined out. It runs great. The only problem I had was it would sometime die at stoplights and it would hesitate after 1st, but it was corrected when the speedometer was hooked up. Now it idles at 1400 rpm until the car comes to a stop, and no hesitation. Awesome wow factor to. If you decide to go for it get a hold of me and I will give you some pointers. It took me a month and a half though, I worked as soon as I got off of work until 10-12 at night and 9am-11pm on weekends. I went through some extra BS though that could of been avoided. Quote
timg Posted June 5, 2003 Author Report Posted June 5, 2003 I'm definitely be looking forward to hearing about it. 1.5 months is quite a while! I'd like to find out as much as I can about the swap before I actually decide anything. Tim Quote
soccrplayrgtp Posted June 6, 2003 Report Posted June 6, 2003 yeah if you are doing a cable clutch talk to him but if you are doing a hydrolic clutch talk to me lol between us we have it overed Quote
Guest TurboSedan Posted June 6, 2003 Report Posted June 6, 2003 can a Getrag 282 hydraulic clutch setup work with the 284? the 284's system seems so much more complex altho i have never really got a good look at a 284 setup. and how/where did he get a cable clutch? homemade? joshua Quote
midstar Posted June 7, 2003 Report Posted June 7, 2003 Slightly mixed up. I have a hydraulic clutch with my 282. I used all the stock components in a 90 STE If you want E-mail me and I will give you my cell #. I won't get you e-mail until I get to work on Monday. I would also like to know about your turbo add-on. I have a friend with a 96 Impala SS and me and him run side by side up to about 100 or so. I kinda need to go faster, he is looking into putting a big block in the SS. Quote
Guest TurboSedan Posted June 7, 2003 Report Posted June 7, 2003 he who? he who is using a cable clutch. i have never heard of a cable clutch for the 282 or 284... joshua Quote
soccrplayrgtp Posted June 7, 2003 Report Posted June 7, 2003 http://www.drivetrain.com/transill_hm282.html thats where I found the info Quote
Guest TurboSedan Posted June 7, 2003 Report Posted June 7, 2003 thanks for the link. i had no idea they actually made a 282 with a cable clutch. did they go in the Fiero's? joshua Quote
soccrplayrgtp Posted June 7, 2003 Report Posted June 7, 2003 actually that was for the chevy's as it says under the tranny pics. So im guessing cavs or luminas or a monte in some year they made em Quote
midstar Posted June 9, 2003 Report Posted June 9, 2003 A cable release might be a better route. My clutch petal barely comes an 1" or so off the floor board and then it grabs and really good too, so it barely releases but it seems to work. I need to make a extension on my clutch master cylinder actuater rod so that I will have more petal travel. Now the clutch petal sets about an 1/2" behind the brake petal instead of infront of the petal like the in the STE. Quote
