(CAUTION: allow the vehicle to cool down fully before attempting any work)
Begin on the vehicle by removing the battery tie down, and disconnect the positive and negative battery cables(10mm).
Remove the battery from the car, and set it aside. Remove the 2 x 10mm bolts securing the battery tray.
Remove the factory air intake box. If you have a short ram, cold air, or custom intake equipped, you may not need to remove it, since there is space around the piping to install the TMM. However, if you wish to remove it for more working space, refer to the manufactures instructions.
Continue by properly supporting the vehicle in the air, and then removing the undertray (if the undertray is not equipped, you may not need to lift the vehicle).
Place a jack underneath the transmission, with a soft material such as rubber or wood, as to not damage the transmission casing, and apply enough lifting pressure to support the engine.
Remove the factory shift cables from the transmission selector with a trim removal tool or open end wrench, then remove the cable brackets, or remove the cables from the brackets.
Now it’s time to remove the factory TMM (if you have an aftermarket TMM, refer to the manufacture's instructions for removal) Use a 17mm socket and remove the long thru bolt securing the factory TMM together.
Next Remove the 2 nuts and 1 bolt securing the TMM base to the transmission. Set the base aside and hold onto the 2 nuts.
Now remove the 4 x 14mm bolts securing the top TMM piece from the frame, and remove the TMM piece. Note, you may wish to un-mount the fuse box to gain better access to these bolts, or use a universal joint to access these bolts.
Install the Damond Motorsports TMM Base on top of the transmission, and secure it to Transmission with the 2 nuts removed before and the new 19mm bolt provided. Tighten to 65lbs/ft.
Now install the Bushing Carrier into the TMM Base. Note: There is a lip on the base, this needs to face towards the engine as show. Insert the 16mm bolt and 19mm lock nut. Tighten to 65lbs/ft.
With the parts installed it's now time to install the top piece. The engine may need to be lowered or shifted to gain access to for the holes to line up on the frame. Begin by threading in all 4 x 14mm bolts by hand, ensuring the holes are lined up. Once the bolts are threaded in partially, tighten in the sequence shown A, B, C, then D to 50-70lbs/ft.
Raise up the engine and align the bushing carrier to the top TMM piece. Once the hole are aligned, slide in the 2 x 15mm provided bolts and tighten on the 15mm lock nuts to 30-40lbs/ft.
Reinstall the shift cables/brackets removed earlier.
Reinstall the battery tray removed earlier, and secure the tray with the provided 10mm bolt and lock nut to the mounting point atop the TMM.
Reinstall the battery, as well as intake if removed. Install is reverse of removal.
Lower the vehicle if supported, and start the engine. Go for a short test drive to ensure the mount is installed properly. There may be added NVH after installing the mount, and the NVH should settle down a bit once some miles are on the mount.
Congrats! You have finished the DM TMM install. We hope you enjoy all our mount has to offer.
