Putting a Getrag in my 93 Auto? Anyone done it? Pointers?

[sxd217]

I am looking at putting a Getrag from a 91 w350 in my 93 w250 that currently has an automatic in it. Has anyone done it? Any advice?

Yeah, I'm planning on puting an nv4500 in my auto, so any help would be much appreciated.

I helped my buddy swap out his tf727 in his '92 CTD to a Getrag. What do you need to know? He bought a wrecked 1st gen with the Getrag and swapped the trans and t-case. I think he had to have a front drive shaft lengthened and the rear shortened. It was not a fun project. If you are going to go to all that trouble I would put a good clutch and a NV4500 in it. He had to get his Getrag rebuilt 5 months after the swap, go figure.

By the time you buy all the parts and do all the work you could have a pretty beefy auto built, just a thought.

If you have a donor truck it really shouldn't be too bad. It is much easier to find clean auto 4x4 than 5 speeds and they are always much cheaper too. I'd rather change a transmission and put new pedals, etc in than swap body parts, etc.

My 92 was auto, the 93 parts truck that I got for the engine was Getrag. I wanted the 5 speed and do not regret the change. (and yes, I have had to rebuild the Getrag, but I still like it. I suspect that if I had opened it up, inspected it and checked preloads I would not have had the issues I did.)

One issue that I ran into other than the driveshafts being different lengths, was that the yoke on the 92 auto truck was smaller than the yoke off the 93 5 speed so when I grabbed the parts truck driveshaft, I had to install a conversion u-joint to fit the auto's front yoke.

Not a trivial swap, but I think it was good for me as I already had the parts truck.

One cool thing you can do if you do this swap is use the tranny fluid cooler for your Power Steering.

I just ran across the front driveshaft difference myself. 93's and some late 92's have bigger yokes and front u joints.
