chadz34 Posted October 12, 2007 Report Share Posted October 12, 2007 I was wondering if a 284 getrag transmission would work electrically with my 1996 Lumina. I know everything will bolt up, and Bake82 figures we can do it in about a weekend. I just happened to wonder about the electrical issues, since a MTX was not used in anything after '93. So, I have a transmission lined up, and a good motor. If this will work the Lumina will be 5 speed. Any input? Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted October 12, 2007 Report Share Posted October 12, 2007 youll have to do something along the lines of jumpering the tranny to make it think that the ATX is in neutral, or something like that IIRC, so that it's not trying to tell a tranny to shift. someone else will chime in, im sure, but i think thats what you need to do to run it on a newer computer Quote Link to comment Share on other sites More sharing options...
Bake82 Posted October 12, 2007 Report Share Posted October 12, 2007 I know on my 88 OBD1 as far as wiring goes I had to change the reverse light connector, and wire the yellow and purple 8 gauge wires together(this makes the car thinki t's in gear all the time) and ofcourse a 5 speed memcal. It's on the OBD2 that I am not sure of, and where this question comes from. Anybody know how it will work with OBD2 and how to get it to work?

Psych0matt Posted October 12, 2007 Report Share Posted October 12, 2007 i thought about that after I posted, not sure if its the same for obd2 Quote Link to comment Share on other sites More sharing options...
Bake82 Posted October 12, 2007 Report Share Posted October 12, 2007 i thought about that after I posted, not sure if its the same for obd2 Me either Chad I think you should maybe post on 60degreev6 or search around over there to see if you find any answers. Also oldskoolGP has a 3.4 dohc 5 spd running on OBD2 so it IS possible! Quote Link to comment Share on other sites More sharing options...
slick Posted October 12, 2007 Report Share Posted October 12, 2007 It will work fine, tons of people are running 282'd 3100/3400 swaps. Quote Link to comment Share on other sites More sharing options...

slick Posted October 12, 2007 Report Share Posted October 12, 2007 Just as Phsychomatt said, I think they trick it into think it's in neutral, or something like that. Quote Link to comment Share on other sites More sharing options...
Bake82 Posted October 12, 2007 Report Share Posted October 12, 2007 Just as Phsychomatt said, I think they trick it into think it's in neutral, or something like that. In the computer? So basically he'll need a tuning software and to play around with it? And then to ground the neutral switch so it will rev above 4k rpm.... I'm only interested because I've offered to help Chad, and I wouldn't want to have everything physically fit in, and then be screwed when it comes to the tuning!

Nah, I think they just grounded out the switch, and everything was fine. Nothing was done to the computers, until they could afford to do so. I wish I had some direct links to these topics, but I don't. Hopefully someone can chime in soon. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted October 12, 2007 Report Share Posted October 12, 2007 You have to wire the PRND321 all into the Neutral. Quote Link to comment Share on other sites More sharing options...
chadz34 Posted October 12, 2007 Author Report Share Posted October 12, 2007 You have to wire the PRND321 all into the Neutral. And other than that, the car will rev to 7k rpm as long as it's rolling. For some reaosn my Lumina rev limiter is not active when the car is rolling, only when in park or in neutral completely stopped, so it must be something for wheel speed?

slick Posted October 12, 2007 Report Share Posted October 12, 2007 The engine should not rev past 4000 while in park. Quote Link to comment Share on other sites More sharing options...

Chad, I think you will want to talk with Josh (oldskoolGP) He has an OBD2 swapped 3.4 5 spd GP. From my brief searching and reading over on 60degreev6, you need to have a tuner to turn off all the transmission codes and maybe someother things( I didn't read it careful enough to know if the other stuff was because it was a 5 spd, or if it was just issues because he switched from OBD 1 to OBD II) this is DEFINETLY doable for you Chad, you just need to figure out the tuning aspect and we can get it done(although probably take longer than first expected due to the dash removal and refitting the steering wheel support.

Yeha I was just on 60DegreeV6 and his car runs a 14.6 I have to find out what all he did to make this happen sure, if we can do it simple enough lets do it. But I don't wanna have it not work and have a hacked up car I could have sold. Pretty much if a 5 speed wont work more than likely I will sell the Lumina and just mod the Z34. That car has been out of sight out of mind for me...I have just been driving moms car, becuase the Z34 needs new rubber since they are original lol.

ns87 Posted October 12, 2007 Report Share Posted October 12, 2007 What about 4t60e from your z34 into your Boomina, and 5 speed the z34? that would be way cooler Quote Link to comment Share on other sites More sharing options...
chadz34 Posted October 12, 2007 Author Report Share Posted October 12, 2007 What about 4t60e from your z34 into your Boomina, and 5 speed the z34? that would be way cooler I've thought about it...but The Z34 has only 46,000km and it works completely fine. I don't wanna tinker with major stuff on that car just yet. I only bought the LS Lumina for winters, or an all season car...so selling it and putting money into the Z34 is what might happen. The Z34 was practically given to me from my parents....they have no interest in it anymore. I am sketchy about driving it alot all of a sudden since it's a garage queen thats why I havent went to get it, my luck the engine would fall ouit or soemthing.

White93z34 Posted October 13, 2007 Report Share Posted October 13, 2007 and Bake82 figures we can do it in about a weekend. :lol: :lol: :lol: Quote Link to comment Share on other sites More sharing options...

Granted my Z is OBD1, but I attempted this tonight, and found that even when rolling I could not rev past 4500RPM. Quote Link to comment Share on other sites More sharing options...
White93z34 Posted October 13, 2007 Report Share Posted October 13, 2007 You can if you are above a certain speed, i forget what it is now but from about 30ish you should be able to free rev all you want. Quote Link to comment Share on other sites More sharing options...
Bake82 Posted October 13, 2007 Report Share Posted October 13, 2007 and Bake82 figures we can do it in about a weekend. :lol: :lol: :lol: Without swaping the firewall plates I don't see why it couldn't be done in a weekend. Have motor pulled Friday night, engine bay cleaned, clutch master hole modified, cables run, pedal mounted(cut brake pedal) and then bolt the motor/tranny back together and back in on Sunday, finish bolting everything back up and fill up the car with fluids and you're good to go! Ofcourse that would be without and hiccups along the way...but I think it could be done.. Ofcouse I totally forgot with the 96 they don't have the clutch pedal bracket already in the steering wheel support bracket, so it would be impossible to do it in a weekend...... But To Chad, looks like this can be done if you want to do it, all depends how badly you that 5 speed manual over the auto Quote Link to comment Share on other sites More sharing options...
