But.....you can see, it has plenty of usable parts to sell and help cover some of the cost of rebuilding the LT1350. I was wrong though and it is an Automatic Tranny.

Anyone know what Transmission would have been in this car?

4L60E automatic overdrive

Automatic 4L60E.

Jonboy · 06-19-2013, 11:12 AM

Should be a 4L60E. The swap is actually a pretty good swap. If it is low mileage, you might not even need to go through it. I had one in a '79 SWB, and I really liked it. For the stand alone harness, check out www.fuelinjectionconnection.com . I bought mine with the swap started, but had to fix a lot of the wiring. Since the connectors are almost 20 years old, a lot of them were damaged. Mine also had accessory brackets from Alan Groves. They are pretty nice pieces, and nicely priced as well.

Would this be a good tranny to possibly just keep with the motor and use with the truck? Right now my truck has a Turbo 350.

I will have to check and see how many miles are on the motor. I dont think it was all that many but I am not 100% sure just how many.

Jonboy · 06-19-2013, 12:19 PM

The 4L60E is just an electronically shifted 700R4. If you have a long tail TH350, it should swap right in. I would leave it, since the PCM will control it.

Sounds like it could be a fairly easy swap.

Looking4shade · 06-19-2013, 10:05 PM

That looks like to Good of a deal to pass up. Unless you're just stuck on ls1 or something that's the way to go. Like the post above lt1swap Has all the information to do the wiring. I sent them my ECM and they reprogrammed it for $75. used original wiring harness and just added and subtracted the wires from there instructions. My wiring expert that's a good friend did it actually I was the helper . There were a few bad Injector and alternator plugs That I had to go to the junkyard and scrounge up But that's half the fun. I'll try to find some pictures of the engine stands And wiring harness that I used .

Looking4shade · 06-19-2013, 11:05 PM

Here's a picture of the engine stands. The Right stands Back edge actually hangs off the crossmember A little bit To give clearance for the compressor. You can Build and L bracket to bolt it or just weld it to the crossmember I can't find my picture of that right now . I made a bracket and bolted it down. If you buy the bracket to move the compressor to the other side You can move the motor mount forward in the bolthole for the compressor And solve that problem. Gas tank is out of a jeep wrangler look at post above.

The most expensive one piece I had to buy was the transmission tail housing kit To make the speedometer work But you have to buy that for any engine and transmission swap. If you don't take the Trans Am let me know and I'll come get it lol

Yes, as mentioned, it is essentially a electronically controlled 700R4 (later 700R4s actually got the 4L60 designation, without the "E"), it is a good transmission, and you will gain overdrive.

Sounds pretty good. I had a 700R4 in an Iroc Z years ago and thought it was a pretty nice tranny.

I've got a 96 LT1 in my truck and love it. I moved the passenger motor mount on the motor to the the standard sbc location. Had to grind the bracket a little. I notched my frame for the AC. Basically the part that is bent up from factory, I bent that portion down. I got my harness from techrods and works awesome. Tell him what you want and done. $410 with the fan option I got. The fuel system will be the biggest expense. Got my lines from pure choice motorsports. I went with a tanks Inc PA series fuel pump. Went with the bigger one for $10 extra. Fired over fist try. Oh, you'll need posi now if you don't have it.

That looks nice. Yeah, I am figuring on a new posi rear end for sure.

Jonboy · 06-20-2013, 11:46 AM

Don't sweat the electric speedo. You can do an aftermarket gauge setup with an electric speedo, or use a Cable-X box from Abbott. The cable X is about $300, the gauges would be up to you. I looked at swapping the tailhousing out on my '79, but ended up using the 90-91 suburban electric cluster, as it is a bolt in in that truck. The VSS signal comes from the PCM, and it is already buffered.

I hadn't even thought about the speedo. Can it be made to use a stock speedo?

Trsmotrhed · 06-20-2013, 02:44 PM

There's all kinds of little things that come up for sure. You'll have to get the box to convert electronic to mechanical or change out the tail shaft. Both seem expensive. I went with a new electronic speedo.

Nice looking. And then you get gauges instead of lights.

That's where the Cable-X comes in. There is a plug that has switched power, ground, & VSS signal in, and teh box converts it to a speedo cable end. You can fine tune it for pulses per mile, tire size, etc.

Oh......I see.

Still learning all the ins and outs of this stuff. Trying to read up on what I can when I can find it.

**jayoldschool** · 06-20-2013, 06:19 PM

You can also use the LT1 Camaro cluster. I swapped one into my Impala SS. It would fit decently in the truck bezel.

Fits the truck bezel well....

JWheeler331 · 06-21-2013, 01:22 PM

Well that is cool. It does look to fit pretty well.

JWheeler331 · 06-21-2013, 02:10 PM

Question;

I am wanting to rewire my truck with a new wiring harness. The LT1350 will be a while before it is ready to drop in so I want to continue to drive my 283 V8 while that one gets pulled and prob. rebuilt.

Do I need a special wiring harness for the LT1? Can I order a regular harness made for my truck from somewhere like LMC or Painless to run the 283 and then it fit the LT1 when its time?
