1993 GMC 4x4 350 ot 5.3 swap

[chevyracer8262]

I've been reading and researching the swap and have found the different adapter plates and flex plates and things of that nature. One of my questions i have is in reguard to my 4L60E thats in my truck. Can I use this transmission with the ls pcm? I'd really like to use it since it was just rebuilt about 10,000 miles ago. can someone pleas shed a little light on what all is involed in a ls swap in a 4x4 truck?

Thanks,

From what I have found out in getting ready for my swap, your tranny will work just fine but you will need to swap the internal tranny harness and the tranny plug for a 95 and newer harness. Someone correct me if I'm wrong

Thanks but I got the tranny situation resolved. I ended up getting the entire engine and tranny from a 2001 chevy truck. Now I have a few more questions can someone please help me with. Does the powersteering lines have the same ends as the OEM p/s pump for the truck? And also how are people integrating the a/c lines? I'm looking to keep the stock accessory configuration on the 5's so i'm gonna make any frame mods I have to mae everything fit. I have a buddy that gonna help me with all the wiring problems and I bought a tuner to take care of all the vats and claibration needs. Anyone have any suggestions or recommendations as to what I may run into doing this swap?

Thanks,

I think you can just use the PS lines that are on your 95 now. Seems like they are the same, not 100% on that though.
For the AC, go to docsblocks.com , they have the adapters you need to go to a standard -8 and -10 set up. There are 2 types of compressors for 2001, so pay attention to the fittings. Some have 1 block for both lines and some have 1 for each.
Use your shifter cable and bracket from your 95.

The PS lines from the 02 Camaro fit right into mine.

Ok thanks I'll give those a try, my buddy told me that if we couldn't find any that would there's a couple places around town that can make me a set. Looks like I'm going to go ahead and freshen up the tranny since I have to disasseble it to change the output shaft anyway I found everything I need to reuild it for $250 convertor included. Also I have the interior with all the wiring for a 98 truck how difficult would it be to make the 98 gauges work with the 5.3? My wiring for the 93 was butchered when I bought it.

Here's some updates of how my swap is turning out, I'm almost to the start up point now and loving the ls motor even more (even thought it's not running yet). All I have left to buy is the radiator hoses and 1 trans cooler line fitting which I will purchase tomorrow..

Here's how my 93 GMC looked when I bought it...

and after I bought and installed my HD Backwoods 18"x9" wheels and 285/65/18 Nitto Terra Grappler Tires

Here's a little before shot of the engine bay and interior as it looked when I bought it..


Here's my 5.3 as it was after we pulled it from the wrecked 01 truck a friend of mine had..


Here's how the 98 dash looked before a couple coats of Duplicolor charcoal grey interior paint...

Now for the fun pix The 5.3 is in and the wiring modified to a standalone harness and installed on the engine... Oh yea all that was after rebuilding the 01 4l60e due to the input clutch set being worn out..

and now all that's left to wire up is the 98 gauges and the hot wires for the engine harness..

And some updates on the 98 interior install...

nice build man how hard was the dash swap to get all the ac vents working and all the wiring?

[chevyracer8262]

Thanks, the dash swap wasn't to bad the hardest part is getting it back in in one piece because they're brittle from the sun. With my swap I swapped everything havc ducting, evap core, dash wiring the whole nine yards because i was able to get everything i could possibly need with the exception on the brake pedal assy (which is a major pita to remove 93 has 6 spot welds the 96-99 has 4 + adheasive) from a parts truck my buddy bought the engine out of and the guy threw in everything else for free so i got both doors towing radiator and as much interior and wiring as we could haul.
