WTB-NV4500-Bellhousing-NP241
 

Looking to locate a good used NV4500 out of a 4wd and a NP241 T-Case and Bellhousing. I want the bellhousing with the external slave cylinder (not inside the bellhousing). I believe the early (93-95?) models were external.

Would prefer a matched set but will take them separately.

Thanks, Mike

I have your NP241. It was in a 91 silverado and behind a SM 465 manual trans.. I dont know if it will work for you, but its like new. Your in luck, im in AZ also...

I dont think it will work if its out of an IFS truck. The drop has to be on the Pass Side to work with my Dana 60 in my 69. I have been searching hi/low and have been "schooled" since posting this ad. I should have put it in the 73-87 section, since only the trucks will have what I need up to 87 (Burbs to 91).

If however, its a PS drop, I'm interested in it. Let me know. If not,I'll have to pass. Thanks for your time either way.

Be careful to check any NV4500. Count splines to make sure the input and output are GM.

There are 2 different transmission to bell housing bolt configurations.

In about 96 they quit using the GM bolt pattern and went to the Dodge bolt pattern for the 4 12mm x 1.75 bolts that hold the trans to the transfer case

External clutch slave cylinder is 92-94 with the oddball bellhousing to trans bolt pattern. GM input shafts are all 1-1/8" 10-spline with a pilot snout diameter of 0.590". The 4x4 NV-4500 has a 32 spline output shaft. Look for an NP-241 that is behind a TH400 or 4L80-E to find the correct 32 spline input gear.

Worthy to consider: Build the correct case from 2...go ahead and find a driver's side drop case from an IFS truck that has the 32 spline input gear, then source a 241 from a square body, split it and put the correct gear in. :D :D :D

I am collecting parts for my NV-4500 swap, so I've researched as well. I started with a 2WD trans and I've collected the 4WD tailshaft, I need the Mainshaft, the balancer, a spacer, and a couple little internal doo-dads + whatever else my trans might need in R&R. I removed it from a '93 C3500 with a seized 6.5L-TD so I didn't get to test it. I have 2 NP241s, both of them out of 90/91 squares with Electronic VSSs, one has 27-spline input from a TH700-R4, the other is the correct 32-spline from a 4L80-E.

Need trans parts? Looky here, they have good used & tested parts for decent prices: http://www.tbtrans.com/transmission_parts.htm
