WhiteOut Posted May 26, 2004 Report Share Posted May 26, 2004 Okay, so I was just reading the post about the L67 that was plopped into a cavalier and they used a Getrag from a sunfire. The page also mentions that this tranny should bolt up to the 3.1 and thus it should fit the LQ1 as well. Has anyone done this to a W-body??? Those Getrags are easy enough to come by since tons of J-bodies have them now days, and the aftermarket has got to be huge compared to the 284 market. Does anyone know why this would be impracticle in comparison to a 284 swap??? Quote Link to comment Share on other sites More sharing options...
WhiteOut Posted May 27, 2004 Author Report Share Posted May 27, 2004 Okay, here's all I can find. Its a Getrag 287 and it can handle up to 250Nm of torque, which is only like 185 ft. lbs. of torque. So it would need some beefing up as previously noted by the guy doing the L67 swap. Its got a first gear ratio of 3.58:1, and it has a dry weight of just under 100 lbs. Basically judging by the specs it looks about like a new and revised 282. So, can it be swapped into our cars with some adjustments??? Anyone???

Baddflash Posted May 27, 2004 Report Share Posted May 27, 2004 I'm pretty sure it could work cause I saw a guy with a cavi who swapped it out for a 282 but they're pretty wimpy trannys ,that's why he swapped it. Quote Link to comment Share on other sites More sharing options...
Heza Posted May 27, 2004 Report Share Posted May 27, 2004 the tranny was designed to work behind the 2.2 4 cylinder...not the 3.4 DOHC. if you could find hardened internals, then maybe it could work. Quote Link to comment Share on other sites More sharing options...

This I'm aware of, and yet you can take your Cavalier or Sunfire directly to a GM dealership and they'll be happy stick a supercharger on the engine for around $2000. AND it doesn't void the warranty from the dealer. Since the supercharger boosts HP from 140 to around 200 at the flywheel, I'd have to imagine torque making a gain to at least 180 up from 140. And the trans is still covered by the factory warranty. So the thing can't be too wimpy. Plus you can get a brand new 5 speed for around $1300, and used ones for around $300. A little work could yield a nice $500 5 speed car. Quote Link to comment Share on other sites More sharing options...
slick Posted May 27, 2004 Report Share Posted May 27, 2004 Interesting.... I didn't even think of that until you posted about it. I bet you could have hardened internals made, for a nice price though. Quote Link to comment Share on other sites More sharing options...
WhiteOut Posted May 27, 2004 Author Report Share Posted May 27, 2004 Well, the guy who did the L67 swap only had a custom flywheel done, and then some modificatoins to the clutch assembly before bolting it up to said engine. And that thing makes WAY more torque than an LQ1 could ever hope to (260 compared to what 200 ft lbs???). I guess I should e-mail the guy and see how his trans is holding up to the punishment. I mean if it can handle an L67 dealing with an LQ1 should be a piece of cake, or at least not much worse than a supercharged Ecotec. Quote Link to comment Share on other sites More sharing options...
slick Posted May 27, 2004 Report Share Posted May 27, 2004 Whats the redline on an L67 anyways? I know i have mine set at about 7100 rpm. I wonder how well that tranny would like that. Quote Link to comment Share on other sites More sharing options...
WhiteOut Posted May 27, 2004 Author Report Share Posted May 27, 2004 I think 5500 RPM is redline for a L67, and LQ1's will go to about 6500. I can't imagine that the trans will have a problem being as it sits behind a DOHC 4 cylinder that reaches peak power at 5600 RPM and has a fuel cut off at 6500 RPM.

GPdriver1986 Posted May 27, 2004 Report Share Posted May 27, 2004 I have been doing alot of research about j-bodies (because I want to buy one) and the 1995-1999 got the Isuzu 5 spd tranny, the 2000-2005 have the getrag F23. On j-body.org they have said that this tranny is built to withstand alot of torque, but alot of them (not all) are complaining of a certain noise these trannys have. You could buy that tranny but get it from 2003-up I heard its better and replace all of the stock GM stuff on it like clutch,bearing,pressure plate,etc, cables, perhaps rebuild it inside.Some people have reported that these changes fixed the problem some of them just put in different fluids to help reduce or eliminate the noise. Overall I'm hearing that its a smooth shifting tranny and its built in Italy. I'm sure its good for w's Quote Link to comment Share on other sites More sharing options...
WhiteOut Posted May 28, 2004 Author Report Share Posted May 28, 2004 According to the Getrag website the 2000+ J-Bodies are using a Getrag 5 speed model 287. What interests me more is what has to be done to this tranny to make it withstand supercharging of the 2.2L Ecotec engine. That and I'd like to know what 5 speed is being bolted onto the 2.0L Supercharged Ecotec thats in the new Cobalt and Ion Redline, that engine puts out a comparable 205hp, and 200 lbs of torque. Almost exactly the specs of an LQ1. I can't find any information anywhere on what transmission this is. Quote Link to comment Share on other sites More sharing options...
GPdriver1986 Posted May 28, 2004 Report Share Posted May 28, 2004 GM still hasn't released any info about the tranny for 2.0L ECO SC but it's gotta be good. From I heard the getrag 2000+ j's can withstand alot of torque (not sure about numbers), I know that GM will be offering a 2.2 ECO supercharger very soon so if the tranny's don't hold its gonna suck.

WhiteOut Posted May 28, 2004 Author Report Share Posted May 28, 2004 Thats it. I'm getting one. Anyone want to buy a 4T60e that was rebuilt about 15,000 miles ago? The rebuild cost me $2000, and included ALL internal parts (clutches, bands, drums, valves, etc...) as well as a new planetary gear set and torque converter. Make me an offer. I'm gonna see what I can do about finding a 287 and having it beefed up a tad for an install into my car. Quote Link to comment Share on other sites More sharing options...
Canada Posted May 28, 2004 Report Share Posted May 28, 2004 So what are the gear ratios for this Getrag 287 (or whatever its called)? I don't know if you guys have noticed this or not......but on gmpowertrain.com GM has the torque ratings for all their transmissions...the only thing is, the transmissions (automatics anyways) usally are rated at the highest peak torque of whatever group of engines its bolted to. So *maybe* this trans has an ACTUAL max torque rating higher than what GM says. If you are going to send any serious form of power through this transmission I would dissasemble it and send the parts off to some place that does cyrotreatment...........its cheap....and, depending who you talk to, dan give a strength increase of 150%-200%. Something to consider at least. Quote Link to comment Share on other sites More sharing options...
WhiteOut Posted May 28, 2004 Author Report Share Posted May 28, 2004 Actually, it turns out I can get the whole trans assembly from a http://www.uneedapart.com vendor for about $250 if I pick it up, and $350 if I have it sent from Detroit so I'm not too woried about blowing it up. I'm actually thinking about trying the swap on my ex-girlfriends 92' GTP. Its been sitting in her yard for about a year now after she rear ended someone, and is basically useless since it doesn't have a front bumper/hood etc...But the engine and frame structure is all there and functional so it would make a good dry run. Wouldn't want to ruin my car if things don't work out. ::EDIT:: My ex's GTP is a 94' not a 92' as I had previously thought. GREAT!!! More issues to deal with!!!

Baddflash Posted May 29, 2004 Report Share Posted May 29, 2004 Not that it's a bad idea to do a practice run, but a 5-speed swap is not the sort of thing you want to do more than you have to especially to a car that you feel is not worth it. It would really have to be a nice car for me to do another swap. Quote Link to comment Share on other sites More sharing options...
loominaz34 Posted June 7, 2004 Report Share Posted June 7, 2004 Is it possible to use a trans out of a land rover freelander? I was wondering because I looked at the getrag site and they have a model 283 that can handle 200 ft/lb. exactly what the LQ1 puts out.

I was wondering because I looked at the getrag site and they have a model 283 that can handle 200 ft/lb. exactly what the LQ1 puts out. Very doubtful, since I'm assuming the freelander is FWD, and the bellhousing is probably completely different. -Tony Quote Link to comment Share on other sites More sharing options...
loominaz34 Posted June 7, 2004 Report Share Posted June 7, 2004 The getrag site shows one pitcure and labels it 281/283/287 and yes this version of the freelander is apparently FWD (front wheel drive). and the weight of the two is within two of whatever they used to measure it. here's a link http://www.en.getrag.de/179/179 I'm assuming by fwd you meant Four Wheel Drive?

5speedz34 Posted June 7, 2004 Report Share Posted June 7, 2004 By FWD i mean front wheel drive, but still I don't think you could use that trans unless the bellhousing is the same. -Tony Quote Link to comment Share on other sites More sharing options...
dbtk2 Posted June 8, 2004 Report Share Posted June 8, 2004 Well, the guy who did the L67 swap only had a custom flywheel done, and then some modificatoins to the clutch assembly before bolting it up to said engine.

I mean if it can handle an L67 dealing with an LQ1 should be a piece of cake, or at least not much worse than a supercharged Ecotec. Stock L67's are rated for 280ft.lbs., but that is actually significantly UNDERRATED. Some people have put out 270 to the wheels. IIRC that is ~325 crank torque. Whats the redline on an L67 anyways? I know i have mine set at about 7100 rpm. I wonder how well that tranny would like that. The redline on an L67 is 6000rpms stock. The stock rev limiter is 5800rpms, and most stock shiftpoints (depending on model) are 5500rpms. The bottom end of the engine is capable of 7500rpm or so, but the topend can't really handle much over 6k without valve float problems. That is easily fixed with the proper mods though. DHP chips in L67 cars run the RPMs up to 6500 RPMs. they shift out of 2nd at 93 MPH. i just read posts at ClubGP on it. A regular DHP will set shiftpoints at an even 6000rpm...with limiters at 6200 IIRC. People with upgraded valvetrains (cam/rockers, valvesprings, retainers, pushrods, lifters, etc...) usually have a custom PCM made with a higher rev limiter and shift points. My dads '02 GTP has 1.9 rockers/85lb. valvesprings, modified retainers, and different pushrods. His rev limiter is set at 6600rpms and his shiftpoints at 6150rpm. He had 3.29:1 final drive gears put in when the tranny was rebuilt...stock is 2.93:1. With his shorter gearing when it shifts to 3rd at 6150 the car is going 88mph...I'm guessing it would do 95+ before hitting the limiter. With the stock 2.93 gears thats like 104mph IIRC...if it was wound out to 6600 it would be like 110+. Anyways, a mildly modded L67 would mostlikely DESTROY one of those trannies if properly abused.
