L92 trans options
Hey guys, I just picked up an 08 L92 which will go into my 72 swb. The guy that I bought the engine from also had the matching trans, an AWD 6L80e. I didn't buy the trans because I understand that the conversion to 2WD is costly, and I'd have to convert to high hump (which I'd prefer not to).
So, if I don't want to cut my trans hump, I think my next option is a 4L60e. But, I think it has to be a current version with ISS. Also, I'm not sure if would need a trans controller to go along with it. Any advice or insight? |

Re: L92 trans options
The 60e is tsking a big loss in strength. The 4l80e woukd be thr next best bet. Its strong enough, u jist lose the 2 extra gears.

Re: L92 trans options
Thanks BR3W, but will the 4l80e fit under the low hump?

Re: L92 trans options
My 66 had the smaller trans tunnel option (idk if my low hump is the same size as yours...pause...) I had a 700r4 in there (basically the same size as the 60e. I switched to the 80e and didn't modify the tunnel at all.

Re: L92 trans options
I've got a 4L85e under my short trans hump...but then again I've had vibrations that I haven't resolved...which could require raising the tail of the trans higher then it is...which won't be possible w/o trans hump modification.

Re: L92 trans options
If a TH400 will fit, you shouldn't have any issues with a 4L80e.

Re: L92 trans options
My thoughts also, work on the rear end +/- difference 2*

Re: L92 trans options
probably.....and yes I need to get the overall angles below 3* for high speed work. The ends have been +/- 0*, 1*, and 2*.....but overall angle is too high tho and why I said I may be changing it.
I want the driveline angle closer to 0 to 1*. I'm up as close to the hump as I can get...thus its coming apart. I've missed racing this year....I won't miss next year!

Re: L92 trans options
Is it a particular rear end setup that is having you run 0-1* on the engine etc? I see most LS's (mine included) installed around 3* down on the engine, and then make up whatever you need to on the rear end.

Re: L92 trans options
With it dropped and the rear now up into the chassis... I'm winding up with a near level (with the ground) driveshaft... yet with more angle on the ends because the trans has 4* down angle yet the rear end isn't much if any below the trans... IS this making any since?
I need the ends to have 0-1* total angle...for little if no movement of the u-joint....at least from what I've read on tuning high speed drive-lines.

Re: L92 trans options
Thanks for the feedback guys. I'm thinking that the 4L80e may be my best option as it should be fairly strong in stock trim behind the 6.2.
But, I'm new to the Gen III/IV electronics. I do have the E38 that came with the L92 and it would appear that I also now need a T42. Regarding the tuning and OS, i understand that this should be from a GM model that had those specific options i.e. L92 & 4L80e. Is this something that a tuner would load in? |

Re: L92 trans options
you'll need a VIN. Didn't happen to get the VIN of the vehicle it came out of?

I'm not 100% sure how this gets on in the e38's, but with the Gen III as an example. Getting a v6 computer would have different colored ECM connectors, and ending up with the wrong ones is just a bigger pain. It shouldn't be that terrible to locate one with your combo. Things like DBW/DBC (At least on the gen III) can be taken care of in the tune as well. I know the e38's have the TAC built in as well, so you may even have some more freedom there.
