The adapter has a provision for a factory GM transmission mount. The adapter kit includes an adapter housing, new long input with 32 spline, input gear bearing, gaskets, seal, fastening hardware and adapter instructions. The adapter assembly fits GM NP with a figure 8 front bolt pattern, and is designed to replace the 10 or 27 spline male inputs. The transfer case will require machine work for the new input shaft in this kit. The 4WD 4L80E must have a 2. Both of these transfer cases used various input splines.

As a general rule, all of the transfer cases that couple to a TH automatic are normally a 27 spline input; when coupled to a manual transmission a 10 spline input; and when coupled to a TH a 32 spline input.

The NP was used from to The TH was equipped with a female 32 spline input, while the SM retained the male 10 spline input. These model transfer cases had a figure-eight front bolt pattern. In to vehicles, GM started using a different version of the NP The input spline for both the TH and the SM transmissions was a female 32 spline, and the front bolt pattern changed to circular bolt pattern.

InGM introduced the NP chain-driven transfer case. The NP also has a circular bolt pattern, and had either a 27 or 32 spline input.

InGM next introduced the NP chain-driven transfer case. This transfer case, as far as bolt patterns and splines are concerned, is identical to the NP The NP is sometimes hard to identify. The data plate for this transfer case is located on the upper front of the case; but many times this information has been worn off, and subsequently a NP gets confused with a NP transfer case. The easiest way to identify the NP is by the rear 3 bolt cover on the idler shaft. NP 3-bolt cover.

The casting numbers on these cases are of no help. The Ford transfer case is the easy one to identify since it is a left hand drop front driveshaft on the driver's side. The cases are identical, both having the figure-eight bolt pattern. Counting the front input gears are the easiest way to distinguish between the two.

The Dodge NP was either a male 23 or male 29 spline input gear. The 32 spline stick out is important to know when adapting to a different transmission. The NP input gears, no matter what vintage or model, are always the same internally.Welcome, Guest. Please login or register. Hello, This is my first post to this forum.

Here's my story. I am swapping a 6. My dilemma is with the transmission and the transfer case. I know the bolt patterns are the same but the adapter on the transfer case won't bolt up because the Transmission mount bolts hit the transmission pan. Does anyone know where I can find the correct adapter?

I've looked and there are hundreds out there and I'm not sure which one fits.

Heres a pic. JPG Any one from a 90's Chevy that had the 4l80e should work, I'm fairly positive that all the transfer cases had the same bolt pattern, at least the Borg Warner I had did, and it was the heavy duty one Sent from my iPhone using Tapatalk. Thank you very much. That's will get me in the right direction Sent from my iPhone using Tapatalk. It's everything. Yeah it's the off the The bolt patterns match it's just too short Sent from my iPhone using Tapatalk.

It is the 4lc kit and made to adapt all the NP cases to the 4l80e. This is my plan when I get to that point! I assume you didn't get the 4L80E to New Venture transfer case adapter with the tranny. The yard goons seem to like to pull the adapter and pitch it in the smelter or evilbay em. Pick one up from Amazon and try it for fit. I'd be willing to bet this will take care of your problem.

If it doesn't fit return it. The TH and 4L80E have the same 32 spline output shaft so that shouldn't be an issue. That should clear up the issue Sent from my iPhone using Tapatalk. Quote from: nighthawker5 on June 12,AM.

Right now it's definitely the adapter. Sent from my iPhone using Tapatalk. If the output shaft is a little long that's not the end of the world. When you swap sides like that the transfer case may hang too high or too low If i do that do i need to do anything with the front differential or driveshaft?Display Options.

These part time, chain driven transfer cases include the New Process, and models. The full time, chain-driven NP transfer case was introduced in the model year.

It was also used in ZJ's. The part time, chain-driven NP transfer case has three major variations.

Not Specified 4.Second question is if I get a 4x4 4l80e do I need to install a speed sensor in the transmission for the ecu and use the current sensor in the t case for the speedo? Or is there better options? Thanks for any help you guys can offer. When using theyou'll need a '94 or later 4L The ' have a force motor that isn't compatible and would need the ' ECM instead.

The forward sensor on the transmission is the input speed and the aft one is output. I'm not an expert on them, but I believe you could use either the one on the transmission assuming it has one, could be blanked off on a 4x4 or the one on the T-case for output speed. Your '87 probably has a DRAC instead of VSSB built into the gauge cluster, I don't recall if that year has a cable drive speedo, but if it does, you'll want to swap it with an electronic speedo.

If it's already electronic, there might be a way to use it with the signal from the VSSB, but I'm not sure. Thanks for the info. Does a 98 4l80e have the same wiring connector as say a 95?? Watch the aftermarket fittings Local GM dealer is selling someone else's fittings in little baggies with GM number on them. This means you might be able to find a guy that can form ends for you.

Possibly AM General for "real" Humvee?? I may have part numbers around. We were using them in buses until tool became available for quick connect ends.

BTW, billygraves, do you know a "real" name for those fittings? We also know to use steel lines here. When high temp paint burns off of cooler lines you know things are hot. Old school bus is a great source for 4L80E trans. We use Parker fittings on the Trans side. I'll probably going the custom steel line all the way to the cooler. Not sure what cooler I'll put on it yet. FYI only. Friend of mine has a 06 he said he'll give me.

Is this something I can use or is there a cut off on the years I can control with the ecu. I picked up a 4l80e with convertor last night. Would I be better running a ecu since that's what came in the tbi trucks with a 4l80e or will the work just fine.

4l80E to TH400 NP205 Adapter/Spacer Kit

I have a ecu I just need the Eprom for it.InGM produced a newer version of its electronically controlled 4L60E. It has a hex bolt pattern on the output side of the transmission, similar to a TH The adapter was designed to make this style of 4L60E look just like a R.

By incorporating a new clamp-on reluctor ring and sensor on this adapter, a 40 pulse per output shaft revolution signal is generated for the drivetrain control module. This adapter kit comes with a new clamp-on reluctor ring that should be installed on the new R output shaft that is also part of this kit.

This clamp-on reluctor ring clamps over the stock governor gear on the R output shaft. We have provided two reluctor sensor locations to choose from in the adapter. The hole not being used will need to be plugged with the plug provided. The one piece GM R4 output shaft used in this kit is made out of alloy steel.

This output shaft is manufactured with the highest quality materials and standards as the OEM output shaft. Both of these transfer cases used various input splines. As a general rule, all of the transfer cases that couple to a TH automatic are normally a 27 spline input; when coupled to a manual transmission a 10 spline input; and when coupled to a TH a 32 spline input. The NP was used from to The TH was equipped with a female 32 spline input, while the SM retained the male 10 spline input.

These model transfer cases had a figure-eight front bolt pattern.

The 32 spline stick out is important to know when adapting to a different transmission. The NP input gears, no matter what vintage or model, are always the same internally.

This allows you to swap the input shaft between the various model transfer cases. One difference that must be taken into consideration is the front input shaft bearing.

4l80e to np208 adapter

The last thing that should be noted is the bolt pattern change that occurred on the case of the GM NP transfer case. Inthe case was changed from a figure-eight bolt pattern to a circular-six bolt pattern. The stock adapter housings that GM used are similar; however, the NP stock adapter housings have a notch in them for transfer case shifter linkage clearance and the housing is 1. NP originally coupled to a TH This transfer case, used in vehicles betweenhas a male 27 spline input.
