I've had significant interest in selling some of the Overland accessories from the LC separately so I'm relisting at a cheaper price with the plan to sell the LC with everything but the crossed out items below.

Current Issues

None of the below are critical in my opinion. They certainly wouldn’t stop me from taking it for a road trip or expedition.

If I were going to keep the LC, the next modification I would make is an manual torque converter lock-up switch. The 4L80E is widely known among the GM guys to sometimes have fickle lock-up (overdrive) behavior. I’ve found a few write-ups out there on how to install one. Another option is to use the TCI TCU programmer to tinker with lock-up ranges. Regardless, I’ve made two trips from Virginia to Colorado/Utah and back, and one trip from Virginia to TX and back (and a few short trips as well). When lock-up is reliably chugging along (the majority of the interstate miles I’ve covered), I move comfortably at 70-75mph.

In my last expedition, the antenna caught a little tree branch action and had to be replaced. After the replacement, the automatic raising and lowering of the antenna doesn’t work. Probably a simple fix, but I never used the feature so I was never pressed to fix it.

The tachometer is disabled. The conversion module to get an RPM reading to the tach came with the Cruiser, but I never got around to installing it.

Notes about the diesel swap

When I purchased the vehicle, it had oil leaks that were a bit more aggressive than the normal Cummins oil leaks/weeps. I had the upper and lower gasket and seal set replaced by a diesel mechanic and now the leaks are more in line with what I see other 6bt and 4bt owners experiencing (barely noticeable). With an 11 quart capacity, I’ve topped off the oil to the tune of a ½ quart at the most - though it probably wasn’t required. But don’t be surprised or panic if you see a few drops in the driveway. It’s normal.

The power steering pump housing was also leaking, but the pump was replaced and the leaking was resolved.

General Notes

I have the 3rd row seat, which will convey with the sale. The platform in the back with various tie-downs and the option for sleeping can convey, or I can trash it. Seller’s choice.

Maintenance records will convey. I’ve kept track of everything I’ve done and I have some of the maintenance and build records from the previous owner.

I also have it listed through the Proffitt's new website (which is kind of full circle since Proffitt's was the original installer of the 4bt).

The vehicle is located in Chantilly, VA 20152


$26,000 $21,000– includes everything listed above; I still have the roof accessories, but a few buyers have expressed interest so if you want them to come with the Cruiser, let me know.
