There isn't a modulator on this trans as it is electronic
You can have first gear going forwrd but no reverse. It is possible. The low/ reverse clutch isn't needed to go forward.

bottom rear of engine on the passenger side, the starter is serviced from under the car. it is held to the engine block with two bolts, then u must remove the battery cable and starter solenoid wiring as well, always disconnect the battery before doing any work on the starter.

If the dash is removed you've saved about 9 10ths of the job endurance. Look around, what you believe to be, the perimeter of the heater box. I cannot, and no one else can, tell you exactly where the bolts and nuts that mount the heater box are. Therefore you must viually sixe the box and check outide in the engine compartment and inside under the dash for the mounting bolts.You'll want to start by removing the heater hoses. Then starting at the passenger side engine compartment look for a group of 10mm or 7/16ths nuts retaining the housing and remove them. Do the same inside. The housing is usually held together with screws or clips, it changes year to year. Keep a log or pix of the wires and cables and hoses(vacuum) that are connected to the housing for reassembly. You'll need to "roll" the box out from under the dash depending on how much of the dash has been removed. The core is easy to spot for is has two hoses sticking out, and, is encircled with clips or screws . Also make sure you remove the bracket around the two entry hoses if it has one. Thank you, Dana

First jack up the truck from the front axle use a floor jack under the front of the truck, take off the drivers side tire beforehand.
Once in the air reach through the drivers side fenderwell and unloosen one of the exhaust bolts, then crawl under and loosen the other. There is NO doughnut gasket as my pipe simply slips into the other and is held in by the pressure of the two pipes nutted together. Next remove the flywheels cover. 6 bolts I believe. It's aluminum or pot metal whichever you call it and slide it around out of the way or else the nose of the starter will hang on this piece.
Next unbolt the 2 bolts holding the starter in place and gently drop it down. Next it may take 2 people to undo the wiring from the starter one from beneath the truck one beneath the fenderwell. Remove the wiring and whoever is beneath the truck should gently wiggle the starter out from between the frame and exhaust and there ya go, it's out.
I just did it so I know my method works. Takes about an hour to an hour and a half to get it out.
