NP205 Customization

June 22, 2015 - Author: CourtneyN

Question: Hi, I am looking for an NP205 to put behind a GM 4×4 NV4500 for my project truck. I think the simplest option would be a customization round pattern, 32 spline input with an Advance Adapters spacer. I think these were used with the TH400 transmission. Is this transfer case one that you can provide or build or possibly recommend alternatives? Thanks!

Answer: We can build a customization round pattern NP205 but there will be tail modifications that you can make on the NV4500 to be made due to the space needed for the shift rail.  A 712529 bracket will also be needed to mount the shifter for the NP205 your cost $75.00. This transfer case is part number TCGM003 cost is $1000 outright plus freight.

1968 Corvette T5 of T5WC

June 4, 2015 - Author: bartbarton

I have a 1968 Corvette.

Question:  I’m looking to drop a T-5 in my 68 vet. Was T5NWC_MTFRD033looking for a world class 1352-176, -182, -196, or -213. They all should be about the same. Was also wondering what kind of torque they are rated for. The engine I am running is a mild 327 with a rear gear of 3.08. I’ve seen some rated for 300 ft lb of torque and others for 600 ft lb torque. I don’t want to tear it up. I see that most of these sat behind a 5.0 liter F-body so I would think they would work behind a 327 with about 350 Hp.

Answer:   The T5 will be a little light for the 327CID with 350 HP it will work if driven only  and not a drag race car.

You would want the T5 Camaro World Class unit and this would have the mechanical speedometer provision required. There would be drive shaft mod’s, cross member mod’s and poss tunnel mods to be made

These are hard transmissions to come by but we could find and rebuild one cost would be $1700 outright no core required, plus freight. Give Scott a call toll free 888-824-2012 he can help you. You can find a complete list of transmission, rebuild kit and hard part for T5 transmissions on our site.

Problems with Dodge NV4500

May 26, 2015 - Author: bartbarton

Question:   I recently purchased a dodge cummins with a nv4500 tranny the clutch was weak after doing a couple engine mods so I decided to replace the clutch along with that I decided to upgrade to the bigger input shaft. When setting the end play of the new shaft I took 5th gear apart and went back together fine or so I thought, it no longer will go into 5th after reinstalling the transmission all other gears work fine including reverse except 5th. I have scoured the Internet for a manual before I take it apart to see what’s wrong so I know how to put it back together. And have turned up nothing. Do you guys offer a repair/ manual?

Answer: Sorry we don’t have a manual for sale. We assume something went wrong with the syncro slider assembly during the reinstall

nv4500The slider will go on backwards…. The pointed engagement teeth need to face the rear.

Why Tire Size is Important

May 8, 2015 - Author: CourtneyN

Question: I have a 1992 4WD GMC Sierra.  The transmission gets stuck in neutral and reverse when it is backed up with transmission in 4 wheel drive any ideas?

Answer: As far as  being stuck in natural or reverse, it shouldn’t make any difference to the transmission if it’s in 4WD or not as far as the transmission shifting unless there is a drive line bind like mismatched front and rear gear ratio’s or mismatched tires Not sure what the problem is suggest you verify it has not had any differential work as in one of the differentials being changed and creating a gear ratio difference… then I would check all tires.. should be within ½” overall diameter.

Give Scott a call 888-824-2012 once you have check these things he can help you.
