Engine/Transmission (1998.5 - 2002) Auto Trans Swap

[Dieseldaddy]

I'm looking to do 47RE to NV5600 swap and was just curios as to what kind of problems to look for? Electrical, Mechanical, Ect. Do I need to swap ECM's also? Any assistance with this is much appreciated!

I know a few guys that have done the swap and are still running there stock PCM. No need to swap ECM. If you need a 6spd flywheel i have a few here. .

Thanks, so is it pretty much just a straight forward swap?

Straightforward ?. Nothing is ever that simple. I put an auto in my manual. Just details. You will have to get your driveshaft(s) length changed. You will need a new trans mount. You will need to put a spacer in your starter. Of course you will have interior details as well. As far as the electronics, I am not sure as I went the other way.

The drive shafts need to be lengthened? Is the trans mount the same just in a different location, or all together different? All the help is appreciated!

I swapped a NV 5600 for a 47RH. My rear shaft had to be lengthened. Yours should be the opposite. The trans mount was different. Not just relocated.

I converted my 47RE to a NV4500 in my '01. Still have both my PCM and ECM but no cruise control, I think the PCM may need to but replaced with one that is the same year and trans. I did have to cut a hole in the floor for the shifter but nothing to bad. The electrical is not bad for the back-up lights. If you have any questions PM me.

So this sounds like it is really a pretty easy swap, just new driveshafts, and a new trans mount, and possibly a pcm if I want to keep cruise control. Thanks alot for the help it's much appreciated!

Don't forget the spacer for the starter

Don't forget the spacer for the starter

Why does there need to be a spacer?

 

[Partyat33]

The flywheel sits closer

Not all trucks require a spacer for the starter.

Mine did not. I have an early 2001.

You guys taking out your auto, I have a 98. 5 5 spd 3500 4x4 that I am thinking about swapping for an auto in mine. Where are you all at? I am in northeast Texas and might be interested in buying or swapping pieces.
