4th Gen Trans Swap Auto To Manual And Vice Versa

**Calibrated Addiction** · 05-11-2014

Ok, some of yall know we did a swap on my truck to a manual trans.

Lucas from East Texas came out to albuquerque and spent a few days.

My truck- 2011 Crew Cab 3500, auto, 4x4 (now a dually also)

Lucas truck- 2012 Single Cab 2500 manual.

The swap went pretty easy for the most part.

The biggest thing is that we needed to get the 2012 to shift the auto. going from auto to manual is the easy part. manual to auto is a headache if you don't have patients.

My truck BARELY fit on the lift.

I got the auto out and truck off the lift so Lucas could pull right up onto when he pulled into the driveway.

Lucas came in and we tore his stuff out. Had the auto out and on the ground in 1.5 hours.

This monster is going into my truck now.

We removed the shifter for the auto from mine. very straightforward to do.

The only thing we had to do was tap the holes for his column to accept the shifter. everything was plug and play.

I did however require to jump 2 wires from my harness to release the key from the ignition.

The clutch pedal mounting is already there in all of the trucks. just need to unpin the pedal and install into mine

Installed a short shifter also (P.O.S. as it transmits EVERY noise inside that transmission and amplifies it into the cab).

Making the template for the shift boot. also moved the cigar lighter to the side.

Dropped the truck off at my buddies upholstery shop to get wrapped in leather.

Used Dzus fasteners so i can remove the boot and get under the console if needed.

Overall the swap was easy.

H&S was a super star in helping us.

Lord knows we called them to fill them in on the swap enough.

The 2012 shifts awesome and we even swapped t-cases.

The 2011 and older trucks have the np case and 2012 and newer have borg warner.

To make the NP273 shift Lucas just had to repin 2 wires on the C130 connector on the firewall.

For the borg in the 2011 I had to run 2 wires from the drivetrain control module inside the cab at the passenger front under hvac unit to the C130 connector on the firewall.

Each of us had to modify the driveshafts since his is a single cab and mine is a crew cab.

Other than that it was fun.

I went with a Southbend 3250DD clutch and larger hydros.

The noise is not bad at all with the latest design from Peter.

I also bought a stock shifter since that short throw is a pile of dog crap.
