mounting holes upward towards the top of the shroud. If you cannot gain enough clearance before the
holes are too close to the ribs in the shroud, you can also do the same to the radiator mounting flanges
where it bolts to the grille, but this is almost never necessary for drop TT installations. Not that if you are
using a body lift without a motor mount lift, you already had to make a fan shroud correction that may
have not been sufficient for use with the TT. Flat TT installations will usually require some adjustment of
shroud position depending on the amount of body and motor lift used.
Issue: Manual transmission sometimes pops out of first gear. If you have a late production 2003
Wrangler or have a ’00-‘03 that has the NV3550 transmission and have had transmission work done, the
dealer may have updated your shifter to the new design described in step 18, and you will need to
perform that step. If you have an ‘04+ Rubicon and did not perform step 18, this problem confirms that
you need to do it.
If you have an older Wrangler, this issue should not occur, but if so, read on.
Solution: Snap the rubber boot around the bottom of the shift lever loose from the center console bezel.
Underneath you will see a ‘fat’ area on the shifter cane – this is both the connection of the lever to the
stub from the transmission, and a large rubber isolator. You will likely find that this ‘fat’ area is now high
enough in the opening that it now can touch the front of the console opening when in 1
st , 3 rd , or 5 th . The
solution is to grind a small amount of the metal housing away on the front side of the isolator (removing
material from the plastic console opening will usually not work since there is a plastic frame around the
base of the boot which is necessary to snap the boot in place). Mark the appropriate area to be ground
and remove the shifter by loosening the set screw on one side. Grind the metal away down to the
rubber, but do not remove much if any of the rubber itself. DO NOT use a torch or plasma cutter to do
this – you will light the rubber on fire and need a new shifter! Reinstall the shifter and test to confirm the
fix, then snap the boot down if the problem is solved.
