You'll most likely have to pry the transmission away from the motor with a screwdriver to help it along. These can take longer to complete and be more difficult to tune. Other major advantages include better fuel economy, less engine wear, quieter cruising on the highway, and in the instance of the typical T5, even better off-the-line acceleration due to a lower numerically higher First-gear ratio compared to four-speeds like the vintage Top Loader. The ratio drops off to 2. You'll have to make a few cuts to the floor pan and install the manual transmission tunnel hump kit. You want a balance between cable tension and no cable tension with the cable slack, yet just short of tension.
The rails are metal tubes where the fuel is delivered to the injectors under high pressure. Chrysler added overdrive units to existing 3-speed automatics: the 904 and 727. . Or talk with Mustangs Plus about a replacement for your project. Other improvements include a 2 inch wide overdrive band, larger overdrive servo, stronger input shaft, and lockup converter clutch rather than mechanical, gear-dependent lockup.

Of course, the most obvious thing needed for this conversion is a manual-transmission pedal set with a clutch pedal.
It comes with a specially designed polyurethane bushing that allows proper driveline angle. It also has the benefits of two gearsets in one, which offers some weight reduction and engineering simplicity with fewer parts. It's time to address the dash area. Dipstick - Maintain the proper fluid level is important and sometimes even critical, to do it you will need the correct Dipstick, Lokare makes a nice piece that will be easy installation and also looks good, they have a flexible and not flexible dipstick, choose what ever you like.

V tool it's embarrassing to call it a tool… that you will get in the Lokar kit will be a littler thinner — 0. Avoid doing the process twice by swapping to a four-speed, then realizing later that a five-speed is clearly the better option. Hughes has 33 different stators with nine fin angle options for this particular 6R80 Pro Series torque converter, giving the team plenty of choices to tailor-fit the converter to a wide-variety of applications. V tool, he explain that the T. This is not an option and is required for this swap.
