Was at the junkyard back in November looking for some parts for a friend and caught a Panther HPP basketweave wheel out of the corner of my eye. Wandered over and saw there was a wrecked 1999 Marquis GS with the HPP package. Opened the door, checked on the trans code and it had a 3.55 open differential.
The car was hit HARD in the rear and the fenders were jamming the wheels. Driveshaft wasn't folded and tailshaft/housing on the transmission were still fine, so I figured I'd take the gamble on the axle not being bent. It only had 80k miles, so way less than mine.
Took some work and swaptronics to get it in my car. Still don't have the speedo working right ... Apparently an orange speedo gear is right for a 3.55 1999, but on a 2001, it's for 3.27 gears. I'm waiting on the speedo gear that USPS lost.
These cars should have all come from the factory like this! It can get up and move now! Still not fast, but at least it can bet our 1.8L/ CVT Sentra to 60 and I'm able to get to speed on onramps easily. I can even light up the tires now on dry pavement
I believe this car has some sort of JMOD done when the transmission was rebuilt at some point. But it works reallll well.
It does need a tune. The computer is programmed to shift out of first at 53MPH at WOT. The problem is, it is no longer capable of that so it'll sit at the rev limiter at like 48 until I let off, then it shifts. I just won't floor it. The speedo gear won't help that problem.
Fuel mileage ( calculating for the inaccurate speedometer) is exactly the same in my daily commute.
