Project WT Waggy - Part 3 - Heart Transplant

[ProTouring442]

Great info guys!

Austin, do you think I should get a tranny from the same vehicle as the transfer case or go with a newer tranny? Im looking for the 6-bolt versions, correct?


How about this one? http://denver.craigslist.org/pts/4114455293.html

it would be nice to get a tranny and transfer case from the same vehicle just so you have all the hardware. if you don't just try and get a tranny with the adapter.

Just watch your Engine/ECM generations. I don't know how much work (if any) is needed to switch the transmission between generations.

I recommend a 96+ 4l60e for ease of installation due to the PWM TCC operation. An older 4l60e can supposedly be made to work, but solenoid and programming changes will be needed to make it work. If mine ever runs, I'll let everyone know if it works or not. My trans is a 94, kind of a bastard.

Just when I think I have viewed all the 5.3L swaps I stumble upon another one!

As stated earlier welcome to the club!

There is good availability on parts/upgrades, and it has the necessary electronic VSS mounted to the tail housing to work your speedo and cruise if you choose to hook it up. You just have to wire up the 4x4 wire from the PCM (Gray with black tracer if I remember correctly) to a switch that goes to ground to tell the PCM you are in 4-low or your tranny won't shift right when you are in low-range.

Question on this. If I am going to keep the stock dash I will need a TC that came with the cable type speedo, correct? I know the SYE kit can either be VSS or Cable. Does the PCM need to know speed or just when its in low-range.

Check this link at. They have some sensors that let you keep the cable speedo and still have vss for the computer.

Also keep in mind that you can change the number of pulses per rev in the computer. So any sensor with pulses can work with ECM programming.

I totally forgot about that site but I think those are for TBI and TPI setups, correct?

[FSJ Guy]

I think the point is that you can get adapters that will give you a cable drive as well as an electronic VSS signal. That way, you can source a t-case easier and have less worry about the VSS signal and speedo signal.

In the link above the #3 option should work just fine. (40 pulse per rev AC sine wave). thirdgen.org has a lot of go info on their site. Here is a good link:

Thanks for the info guys. I plan on hitting the JY tomorrow to look for a 96+ NP241c TC and floor shifter. Wish me luck

Wish you were closer. Have one sitting in the garage.

Me too!

I didn't find a TC at the JY today but I need manage to find a decent floor shifter assembly and trim. Another piece down, many more to go!

Anyone have a recommendation for an affordable radiator? BJ's is out of stock and won't have any in the near future. The Novak radiator is twice as much as the BJ's!

What's wrong with the stock one?

Check out this thread:
http://www.fsjnetwork.com/forum/viewtop ... 075#p27075

The lower hose is a Dayco 71989 which is an upper hose for a GMC 1500 with a 5.3.

The upper hose is a Dayco 71690 which is an upper hose off a Buick Century 3.1 V6.

He had to trim a small amount off of each for proper fit. They look like they were made for
the conversion.

Thanks Lobie, I didn't realize he was using the stock radiator in that thread. I never really thought about it, I guess there is no reason why not if you have the correct hoses. It's hard to tell from the video but I think he is using an electric fan. I planned on using the stock fan clutch and that lower hose may be in the way of the fan.

[msh227]

I kept the stock radiator as well. I had a local radiator shop swap the ports for $100 to match the stock gm ports. Money well spent.

Yes he has an electric fan. He's in our CFSJC. It would hit a mechanical fan. Any reason why a mechanical? There's great advantages to the electric and can control it with the ECM. I am also going to put a switch to manually operate it as we'll as use the ECM

Summit of jegs has some electric fans for a decent price. 16" would work.
The only reason I used a different radiator was because I had it laying around. Otherwise I would have used the stock one.

Also a good option. Then get a straight water neck like I'm using in my build thread.

I have a aluminum radiator, shroud and electric fan in my garage now I can use. I think I will see if it can be modified, although modifying a aluminum radiator will probably be much more than a stock radiator.

updates?

[ProTouring442]

I don't know if you've solved your radiator conundrum yet, so I throw in too. CAPTSmith and I (and maybe a few others) used a Griffin radiator made for an LS swap into a first Generation Camaro ('67-'69). Through Summit Racing it's part number GRI-8-00009-LS RADIATOR and it currently retails for $267.39. The disadvantage of this unit is you'll have to run a separate transmission oil cooler (it has no internal cooler) and a thermostat to ensure you bring the transmission fluid up to temperature. The advantage is that it bolts right in to the Jeep's radiator support, and is readily available if something were to happen to yours. CAPTSmith also used the GM fan, fan-clutch, and an aftermarket fan-shroud, but I don't know the manufacturer on the shroud.

updates?

No updates right now, still trying to get the $$ for a transmission. I did get the engine moved over to my buddy's shop where we will be doing the swap.
