In today’s episode of Back Yard Build, we’re continuing the series where I flip cars to save up for my dream ride — a Dodge Charger Hellcat Widebody. This time, we’re diving deep into the 2004 Chrysler Crossfire and finally tackling the weird transmission issue that’s been driving me crazy.
The Crossfire was randomly downshifting, upshifting too fast, and jumping into fourth gear at low speeds… so today, we diagnose the problem, pull the car into the garage, and replace the valve body in the 722.6 automatic transmission. Once that’s fixed, we install the front lowering springs, check the shocks, and give the Crossfire the stance it should’ve had from the factory.
After that, we head out for a full road test, dial in the fluid level, and make sure the transmission shifts perfectly. With the mechanical issues fixed, this build is finally ready to move into the interior cleanup and detailing phase so we can get it listed for sale and move one step closer to the Hellcat dream.
Plus — today’s video is sponsored by VIOFO, and I install their A119 M Pro dash cam in my Camaro and show how well it captures daytime and nighttime license plates thanks to the Sony Starvis 2 sensor and 4K 30fps recording.
