maybe stupid question, but: why does noone use the complete Dodge truck trans (I think they are called NV5400)? Are they that huge, I eman the A518s are usable in muscle cars too? Wrong gearing for street car? Would tehy fit into a C-body (I got one...)?

The NV4500 is about 100kg, has a 6:1 first gear and a monster shifter coming right out of the top of the transmission. It would be a conversation piece, that's for sure, but I wouldn't want to try to drive a car with one!

Clair,
this is a Bellhousing from a 1987 Dakota V6. What do you think? Does it fit?
Btw, I just bought the Supra tranny...

the NVG1500/1550 replaced the AX15 in 4cyl jeeps and 4cyl daks, and that's a very weak tranny--I wouldn't put it behind a V-8. the NVG3500/3550 was behind 5.2's in dakotas and rams, but they are physically very large, and have an integral bellhousing, like an auto tranny. IIRC they're rated from NVG for 300 ft-lbs, and because of that were never offered behind 360's in 1/2 tons, only 318's. I had one in my truck, ratios were nicely spaced, but I don't think it would be worth the hassle (you'd have to do MAJOR surgery for this one--it's physically larger than a tremec TKO) the NVG4500 was in 3/4 and 1 tons, it's a cast iron 5 speed with low (6:1ish) first gear, and is very beefy, but not performance oriented, and larger than the 3500. the 5600 is the cast iron 6 speed that was offered in 1 tons. it makes the 4500 look small. I used to work for the company that built all the shifters for NVG and the Tremec T-800 tranny in the GM pickups (In fact, I did some of the design work on the tremec shifter)

That would work with the A-435? 5-speed, but not the Supra trans. You have to use the bellhousing from the AX-15 transmission, as it bolts up the same as the supra. You can see how strange the supra trans bolt pattern is when you take the supra bell off.

Clair,
a 143 tooth 318/ or 340 steel crank flywheel 10.5 inch clutch? Is this good? Or does it has to be a Dakota one..........?

I *THINK* that any 143-tooth flywheel will interchange, but don't quote me on that, I haven't verified. The Dakota V-6 flywheel I've got looks the same as my 130-tooth flywheel, except larger diameter. I need to put them on a flat surface and compare critical dimensions for depth, but they LOOK to be the same. The nice thing about the Dak V-6 'wheel is that it uses a 10.5" clutch & pressure plate, just like the OEM 340's. The smaller clutch disk will shift easier since the synchros in the trans don't have to stop as much mass as a larger flywheel, and the lighter rotating mass on the flywheel will let the engine rev easily. Going to the larger/heavier parts really hurts performance. A nice combo MIGHT be a 143-tooth aluminum flywheel with a 10.5" clutch disk & pressure plate.

Clair, any news from your project?
For me it's hard to find the bell and flywheel etc... in other words the US parts...

No progress on my end, I've been putting all my time (all 3-4 hours per week ) in to getting my EFI running better, now that I have it running at all. Another resource for you might be the little 4-cylinder diesel engines in the Jeep Liberty, and perhaps others over there that use the same engine. They use (from what I understand) an identical flywheel/bellhousing setup. I haven't compared them up close and in person, though. The bell is the magic part, I think just about any 11" flywheel would do the trick.

Clair, do you think the 3.9 and the Diesel Bellhousings share the same P/N's? These parts in
used condition are really hard, would say impossible, to find here in germany. And new? Cant belive the price.... 4 digits w/o a dot in it!!!
My 904 gone down these days and I saw that my crank has the drilling for the pilot bearing. Good to now...

What Efi are you running? Think I can take advantage of your knowledge...

You'd have to check the PN's on the 3.9/diesel bells to see if they were the same. My only real concern with the Jeep diesel bell is that Jeeps frequently have the starter on the passenger side for space, but I don't know if the Liberty is the same as the Cherokee/Grand Cherokee in that respect.

My EFI is from a 1990-1992 Camaro Z-28, and I'm recalibrating it to like my 72 340 with cam, headers, etc. So far, it's very frustrating. Think of tuning a carb where you have to choose from an infinite quantity of jets, air bleeds, and emulsion tubes... Getting closer, but I'm not very patient...

It appears that the CRD Jeep bell has the starter on the driver side like a "normal" car.
I'd be surprised if it wasn't the same as the Dak part, but never say never, especially with the late Ma Mopar.

If you simply can't find the parts they can always be shipped over there. I know that's expensive but it can be done.
If I was planning on another trip over there, I'd carry them with me. I am overdue for the trip. My last visit was for the Grand Prix of Europe at the Ring in 2005.

duh, what a nice offer! Can you figure out what shipping would cost? Bell & flywheel?

If you are coming to europe/germany - let me know...

Two friends of mine will come over in September... They might have some space in their suit cases too.

Flo, if their suit are big as a trunk - would be great. Please ask them.

The other problem is that I still can NOT find any of these parts. Not in the States, not in Europe..... (bell, flywheel, hydr. clutch.)

Hi Clair,
can you see by the picture if this bell fits?

Seller says 1997 3.9L V6 Dakota with all the conversion parts (for a Dakota tranny swap).

That looks like the stuff. I think my bell is also from a 97 V6. The flywheel should work fine, as would the pressure plate, but the clutch disk will have a different spline than the Toyota disk. If you used the AX-15 trans, it would be a non-issue. The driveshaft yoke will also have a different spline, as far as I know. I'd have to do some searching to verify that the driveshaft yoke was the same spline as a 727 or 904, though. I'm not sure how Mopar handled that one. I've got an AX-15 in the garage, I guess I could check that one of these days...
