Hello folks,



On Nov 27 Flight704 inititated a (to me) very intersting thread about using a NV3500 tranny in his/her Dart. Good discussion with certified wizards contributing, but to me it kinda died out. Well this weekend a board wizard rang my bell and made me remember that thread with a suggestion I look at using a New Venture NV3500 (Getrag (HM290 or MG5) tranny. I was down the T5 road but suspicion a T5 may not last long in a 5300 pound vehicle.

My application is a '64 D100 with a built slant six and a 3.91 sure grip on an 8 3/4 axle set. I did the A833OD 4 speed swap, now want to try a 5 speed, but not the NP with the granny gear. Seems the NV3500 for a '00 to '04 Dodge Dakota might even bolt directly up, according to urban legend.

(1) But I haven't found the gear ratios for a 2000 3.9 litre engine Dodge Dakota 4x4 toploader ranny I picked up, and hope someone knows or knows a site to look at so I can think about the gears and their spacing.

(2) The tranny has a flange on back for the transfer case, but no transfer case came with it. Is this any problem with using it for my 2wd app?

(3) I have seen sixinthehead's in his car, but think his was a 6 cyl tranny...will the 3.9 fit a slant six, and does this then get into changing flywheel and clutch plates to accomodate the splines on the NV?

Thanks!

Well, the forum never fails.

While not knowing answer to my flange and clutch quest's, within minutes of post a forum member sent me this site and this ratio set:

http://dodgeram.org/tech/transmission/nv3500_spec.htm

NV3500 and the narrow ratio used in 2500LD's is close to the T5 at:
1st - 4.01 1st 3.49
2nd - 2.32 2d 2.16
3rd - 1.40 3rd 1.40
4th - 1.00 4th 1.00
5th - 0.73 5th .73

Getrag Corvette
1st - 4.23 1st - 2.97
2nd - 2.53 2d - 2.07
3rd - 1.67 3rd - 1.43
4th - 1.23 4th - 1.00
5th - 1.00 5th - .71
6th - 0.79 6th - .57

best wishes to all!

The 3.9 V6 uses the LA (small block) V8 bellhousing pattern, not the same as the G (slant-6) bellhousing pattern.

Dan,

Great advice, as always! I have one of AndyF's tranny adapters. Since Andy's fits the V8 automatic and will go to a 318, might it be possible to use the 3.9 with Andy's plate onto a slant six? That would be a pleasant finding!

An adaptor that'll put a V8 automatic transmission behind a slant-6 should work just fine to put a V8/V6 bellhousing + manual trans behind a slant-6. You may need to do some clever figuring on how to take up the extra space created by the adaptor plate.
