billyjones454 Posted December 31, 2020 Share Posted December 31, 2020 Hi, I'm doing an LS3/4l80e swap. I've got a Camaro oil pan under the engine, and the 4l80e transmission pan sits way lower than the pan, and is the lowest part of the drive train by a fair amount. My cross member has a ride height of 4", and my transmission oil pan is at 2" from the ground. Are there any aftermarket pans for the 4l80e that would give me a little more clearance? Is there anyone out there that has done a swap with a 4l80e that could chime in on how they set up their engine/trans mounts to accommodate the lower pan? Thanks!

Spdrcr Posted January 2, 2021 Share Posted January 2, 2021 I am doing a 4l60e and it’s tight! If the 4l80 is bigger I don’t envy you. do you know how you are going to run the exhaust? I’m worried it is going to be low. Quote Link to comment Share on other sites More sharing options...
Spike243 Posted January 2, 2021 Share Posted January 2, 2021 I've done an ls/4l80 swap in a 280zx and I didn't have any issues with trans pan clearance. I'm not sure which chassis you are using so it may be different for you. I used a stock pan on mine and with a custom trans mount my pan is above the frame rails. Are your driveline angles looking good? I ask this in case the tail end of your transmission is sitting very low causing both clearance issues and angle issues. Like Spdrcr said, the 4l80 is tight. I had to do some serious clearance work to get things to fit and my exhaust exits below the engine bay. Quote Link to comment Share on other sites More sharing options...
Spdrcr Posted January 2, 2021 Share Posted January 2, 2021 I’ve got a 280z. The angles look good. I’m using the JCI kit and they seem to have everything sorted out. Quote Link to comment Share on other sites More sharing options...
