Engine Level or narrower transmission?
Engine Level or narrower transmission? Trial fitted the plastic LSx engine with a GTO front sump oil pan and empty 700R4 (4L60E) transmission housing into my Benz. The transmission is about one inch too wide (13") to fit up in the tunnel. If I leave the transmission below the tunnel opening, the engine is sitting at an angle in the engine bay, nose high and looks like it will make a rather interesting angle for the driveshaft to accomodate. I didn't really want to modify the floor pan of the Benz as it's multiple layers thick under there and very strong. I might be able to modify the pan to drop the engine an inch or so.
So, here's the question: can an LSx operate somewhat nose high or is there another automatic transmission that will take an LS6 output but is narrower than 13" across the pan?
Thanks,
Mike R.

I'm not sure about it being narrower, but a 2004R transmission is definitely shorter and still has overdrive. See the dimensions here: http://www.tciauto.com/tech_info/trans_dims.htm
They can be built to handle the power behind a built turbo V6 so they should be able to handle and LS6 too. Do you need to run a front sump pan like the GTO pan or can you use a F-body pan? If so the stock F-body pan might work or you might be able to use the Street and Performance modified (clearanced) pan or I think John B has a guy that can modify them. There's probably more info on the pans in the stickys at the top of this forum.

There is interest in a kit for my "LSx into Benz" work, and I really don't think including a five-pound hammer in the kit would be looked upon as a reasonable solution! :-)
Good idea though.
aww comeon, a singlejack is a man's best friend. next best thing is get a cutoff wheel and fabricate/find a tunnel that can fit.. or a transmission that doesnt affect clearance, like 350ss said...

2. vote for the 200R4! But its low tech and i think a Benz owner would love the new features a 4L60E and up transmissions have on the CPU side.
I guess the way to correct the angle is the K-member and Oilpan choice !

I went back out and took another look at the clearance problem and it looks like I only need another inch in width for maybe 4 inches at the front of the tunnel. I'm not thrilled with the idea of using a BFH, but I think a bottle jack (singlejack?) would do the job. Same result, move the metal out of the way of the transmission. That way I keep an electronic transmission in there, which is a good thing.

Instead of a bottle jack see if you can find a porto-power. You may be able to rent one. Since it is designed for body work it will do much better than a bottle jack. I agree the best solution is to modify the tunnel, even if you have to cut a small section out and put some new sheet metal or even fiberglass in there. Having the engine placed properly is critical to a smooth running car, especially in a high performance application. My $.02

you could use a porta-power, (kinda like a specialized bottle jack) but i would just cut the tunnel and mod it.
sure its "strong metal" but its still no match for normal cutting tools.. yea it'll be a PITA welding back together, but its not impossible.. doing it this way will yield the nicest result..

If it's a one spot the hammer trick should be OK. If it's the whole tunel I would cut it out and get your drivetrain set and then take it to someone fab up another piece of metal and weld it back in. GL

I'm using a plastic LS1 engine with the GTO oil pan and an empty 700R4 transmission housing to do sizing, motor mounts, etc. Since I'm working out of town, I have had very little time to mess with the Benz to figure out things like this. In fact, since I put the engine/tranny in there, I haven't had enough time to even jack the car up enough to really get under there to see what's happening. Not good progress so far. :-(
I can look down from the top and see the interference, but it's going to take a short trip underneath to determine the extent of the problem. Maybe this weekend I can put it up on jackstands and get under there to see exactly where the interference is occurring and how much the tunnel actually needs to be moved.
Thanks for the suggestion though.
