I wonder if you could give us some insight on a few things with that motor tranny combo to see if there is really a difference?

What is your RPM at 55mph, 65mph, and 75mph in 5th gear?

What speed are you showing in 1st at 5000RPM, 2nd 5000RPM, 3rd 5000RPM, 4th 5000RPM.....oh and 5th at 5000RPM!! :wink:  :lol:

Better idea, what is the final drive of the L-Body 282?  Get that, and go here...

Find your Speed per RPM up to 8000 :wink:  even better, and you can actually get it to 5000 in 5th gear :P

well my hopes of using a Getrag 282 from a J/L-body went right out the window.  my brother and i went down to Denver today to go junkyarding.  i immediately found a 2.8/5-speed Beretta and found some big problems:

- the slave cylinder setup is way different.  on a W-body 282, the slave cylinder attatches to the transmission and actuates the throwout bearing shaft inside the bellhousing.  however, on an L-body 282, the slave cylinder mounts onto a bracket, and actuates the throwout bearing outside of the bellhousing!  hard to explain but it's very easy to see once you take a quick look underhood.  now for a minute there i was thinking that i could simply switch over to the L-body style slave setup (which would require swapping out the TO bearing shaft too), but there is one big problem with that - the slave cylinder and bracket is placed right where the turbocharger on an LG5 engine would be :icon_confused: 

- the other HUGE problem is the L-body 282 case itself.  it simply CANNOT be used in a W-body because there is nowhere to bolt up a W-body 282 tranny mount.  there isn't even a boss there that you could drill & tap - the case appears to be a completely different casting.  the L-body 282 doesn't use a mount that sits between the cradle and transmission itself like a W-body 282 does.  it uses what looks like a dogbone style mount on the front lower side of the transmission, and another one on top of the transmission in front of the throttle body.  the upper tranny mount actually doubles as the slave cylinder bracket.

i must have found at least 10 Getrag 282s in Berettas and Corsicas.  every one of them was between '88-'90 so a later year L-body may be different.  i did not find any Getrag 282s in J-bodies, however i did find a '91-ish 2.0/Isuzu 5-speed Cavalier and it had the same wierd external slave cylinder type that the L-bodies had.  one thing i noticed was that the Izuzu trans (RPO MK7) looks wayyy different than a Getrag 282.  i only found one W-body Getrag 282 which was in an '88 or '89 Grand Prix.  i grabbed the shifter, cables and shifter boot from that car so i would have some extras.  the j/y that had this GP was selling transmissions for $29.99 today but i decided not to pull it.  fluid was pretty low/dirty and the outer end cap for the TO bearing shaft was missing.  likely would have needed a full rebuild so i didn't bother with it since i already have an extra perfectly good W-body 282 sitting in my garage at the moment.  oh, i also got a nice sunburn :icon_lol:

anyway, i think the only way you could gain the benefit of the L-body 282's lower 1st and 2nd gear ratio (numerically) would be to have L-body 282 internals installed into a W-body 282 case.  or at the very least get the W-body 282 rebuilt using 1st and 2nd gears from a J/L body 282.  i am not sure if this is possible or not?
