Ok, at least we have a whole week to think about it.

Re: Putting 4.7 V8 from 01 GC into 03 GC

Okay, so I just swapped the wiring harness. I had to disconnect the transmission cross member and lower the transmission/transfer case to make room to slide the thick bundle of wire between the top of the throttle body and the cowl, and I had to remove the starter to get to the crankshaft position sensor. What a messy, knuckle-busting, frustrating pain in the a**. It took me about 3 1/2 hours. It would have been 3 1/2 minutes if I had done it with the engine out of the car. Oh well.

Re: Putting 4.7 V8 from 01 GC into 03 GC

And I made an extremely boneheaded mistake which I now have to fix. After I got the harness in place and all plugged in, I was raising the transmission/transfer case back into place so I could reattach the transmission cross member, then I was going to work on reconnecting the exhaust system. There is an exhaust hanger bolted to the passenger side of the transmission. Mine was loose, and as I was jacking up the crossmember, somehow the hanger got wedged up against the transmission oil pressure sensor (generic picture attached) and broke it off. The end of it is still in the transmission (everything from the outer blue O-ring to the very tip). I don't know how I'm going to get it out. It's got a hole in the middle, so theoretically I could use a drywall screw or an easy-out, but I'm afraid I might push it all the way in and never find it again. Goodbye transmission.

One possibility is if it's accessible from inside the transmission, I could drop the pan and fish it out from there. Looking on the bright side, this gives me a chance to replace the filter and fluid, which I wanted to do anyway. Frango, you seem to be the only one who's reading this thread, and you recently replaced your transmission. Do you know if the sensor tip is accessible from inside the transmission pan area?

Re: Putting 4.7 V8 from 01 GC into 03 GC

I was looking at auto parts web sites to find out who stocks transmission filters and how much they cost and some of them show an external filter that looks kind of like an oil filter. Where would this be located? How do I know if I have one or not?

I got it out

I bought some fish hooks and straightened one out, stuck it down the hole in the middle, hooked it behind the remnants of the plug, and pulled it out. See attached picture.

What's left?

Here's a list.

Definitely to do:

- Wait for new transmission oil pressure sensor (the one I broke) to arrive from RockAuto.com and replace it
- Reconnect exhaust system
- Replace broken ground strap between exhaust pipe and transmission
- Plug in the O2 sensors
- Reinstall and connect starter
- Replace front and rear driveshafts
- Re-connect track bar (I had to lower it for clearance to remove engine)
- Reconnect heater hoses to engine
- Bolt in A/C receiver dryer (I will wait til later when I am ready to recharge the A/C system to actually hook it up, but I need to put it in before I replace the radiator overflow tank and battery tray)
- Replace battery tray
- Replace radiator/condenser/power steering cooler/cooling fan/shroud assembly and connect all hoses
- Replace radiator overflow tank
- Fill radiator with coolant
- Fill power steering pump
- Put in battery and start it up!

Might do:

- drop transmission pan and replace filter. I've already lost so much fluid because of the broken transmission oil pressure sensor that maybe it would be a good idea to replace the filter and put in new fluid

Re: Putting 4.7 V8 from 01 GC into 03 GC

Sorry, i overlooked your thread the last few days.
You got the broken piece out already, but there is no way to access the line pressure sensor from the inside.
There are two filters inside the tranny pan, the oval shaped inlet filter (take care to get the one for 4x4 drive) and a round spin-on return filter. Not sure about the quality of non Mopar brands, but there where issues with the spin-on filter from Mopar in the beginning, a checkvalve inside the filter was not closing off properly causing the torque converter fluid to drain back to the pan. This caused delayed engagement at first startup after several hours being off, due to the torque converter which had to be filled up first. The Mopar filters are ok now. I used once a non Mopar filter which also showed this drainback problem, but donīt know which brand it was.
A good place to buy transmission electrical parts and filters is: www.electricaladvantage.com. They use OEM parts.
Also when changing the oval shaped inlet filter, take care of the following: the seal on the filter neck has to be installed in the pump inlet first. Put it in place with the butt end of a hammer or alike until its completely flush and then install the inlet filter. Installing it already on the filter neck can result in detaching of the filter and a pump which will suck in air only, so loosing the transmission functions and a change of severe internal damage.

Re: Putting 4.7 V8 from 01 GC into 03 GC

Well, I finally got it all put back together and it's running - I actually drove it today! There were two major last minute glitches that took a lot of my time to fix. One was the starter. I reused the starter from the 01 engine. Believe it or not, the starter changed from 01 to 03, not the starter itself, but the electrical connector. I broke the outer plastic part of the connector which encloses the actual electrical connector that's attached to the starter during the engine swap and I crazy glued it back together. For some reason the electrical blade connector would not line up. I had to take the starter loose and then I broke the part that I had glued completely off, which made it easier to plug it in, but now there is nothing locking the connector in place, and it's exposed to the elements. So I need to figure out some way to make that connection better, but not right away. The other thing that caused me a problem was the power steering system. It was low on fluid and full of air, causing it to make a lot of noise. Frango, I just stumbled across another thread in which you advised turning the steering wheel lock to lock 20 times to de-aerate the system. It was easy for me to do this because the car is up on jack stands already so the front wheels are in the air. I had one of my sons turn the wheels with the engine off while I looked into the power steering reservoir, and I could see the bubbles coming up, until they stopped. I ended up having to put a lot of fluid in there, but no more sound.

So I'm done. This was a huge project for me, and it took nearly three months, because I am working outside and the weather has been really bad this year. After I recover a bit from this hellacious experience, I might post some more photos, but for now, the engine swap looks to be complete. In the future I need to tweak the car with other, more standard type repairs (brakes, suspension, etc.), but for now, I need to relax.

Congrats on the result. It always gives a good feeling when you finish a job, especially a big one like this.

Re: Putting 4.7 V8 from 01 GC into 03 GC

Thanks! Actually the engine has given me no problems. The car continues to be a little bit of a project, but I can drive it while I'm working on it, which is how I like to do it: always keep your car on the road. Since I replaced the engine, I have also replaced the tie rod ends, tie rod and drag link, steering damper, front brake rotors and pads, control arms, and axle-mounted front upper control arm bushings (I could start a whole new thread on that nightmare!) Last weekend I finally (now that it's turning cold!) finished putting the A/C system back together, and discovered that I have the dreaded broken blend door issue, with a broken recirculation door also thrown in for good measure. I think I'm going to be taking the dashboard apart soon, which saddens me greatly.
