Anyone have one or seen one? I read in a mag where the last one's (np 205) Chevy put in there trucks had a VSS.

With my chevy FI and my dreams of a 203/205 doubler one day it would be sweet to find one with the mentioned VSS for a cruise and electric speedo :D

Anyone??

Thanks!!

Yeah I had one,and have some of it left somewhere.

Yep they exist ... had one a couple months ago ... it came from a 90'ish 1T 3+3 mated to a SM465.

I have one in my garage, Part of a th400/205 setup for when my 700 blows. I can answer any questions about it.

90 & 91 "V" series crew cabs and possibly cab & chassis trucks had VSS 205's.

So they do exist!!

Some pics would be great it possible!!

Thanks for the info guys.

I installed a 205 in my 91 burb. I bought an aftermarket speed sensor, had a reluctor out of a 241 machined and sleeved to replace the speedo drive gear, and had the output housing machined to accept the speed sensor. Works great now!

Cool!! Sounds like a possible fix. Will have to check the 241 I have and see if the VSS is still there.

Got any pics? What did the machine cost run ya?

Thanks for the info!!

I have a 203/205 in my jeep xj with a speed sensor I bought for the ford 205. Mine is a 3 wire VSS and it works. Only problem is they are different and it shows me doing 90 when I'm actually doing 45! I'm looking for a true speed type device that will get the pulses right and not break the bank. The guy I bought the speed sensor from will make on but it will cost + $120.

I'm selling a Superlift Truespeed that came out of my 94 GMC. I'm not positive if it will work in your application.

Go with the gear drive and inline pulse adapter-then you just have to change the colored drive gear for you ratio application to get accuarate speedomter readings....or you could add an adjustable speedo gauge with the toggle switches on the back.

I've been trying to find a solution for this aswell... has anybody used one of these?... I'd like to get some input before I lay down the cash

I spoke with JTR some time ago about getting a VSS signal from an NP205 and was told their speedometer cable-based adapters would not work (at least in my application). The only suggestion they had was to use their externally mounted 40 tooth reluctor ring and sensor.

If anyone has found another workable solution, please post it up . . .

Im also in search of the same thing. I need 40 pulse for mine.

I tried just about every option I could find, including JTR.

I finally settled on having the reluctor machined and the tailshaft housing machined and then used an aftermarket sensor, works great.

I can post pics if you want.

definitely post pics please. I am open to all options. If I can come up with something different I will post it up.

and if you would, post the pics to the NP205 thread too... thats good info we could use there.



and if you dont, im stealin em anyways!

I have a ford unit with a vss I bought from a guy in California. I'll try to find the shop name and number if you guys are interested. www.speedometerplus.com is where I got my sending unit. I hooked it up and the speedo basically was double my actual speed. I did a little research and just ordered this from a guy on ebay: http://www.dakotadigital.com/index.cfm/page/ptype=product/product_id=126/category_id=287/home_id=59/mode=prod/prd126.htm

From what he tells me it can be adapted for just about any spedo sensor to just about any spedo.

the 2, 4, and 8, pulse per revolution is not a problem to obtain. thats a readily available part. Its the 40 pulse thats hard to find without fabbing something up.

The other problem is VERY few 205's have any kind of VSS. So there is no signal to convert with that unit from dakota. And in order to get the correct reading regardless of what gear you are in you would need the VSS to read the transfer case output shaft revolutions.

Yes but if you call the guy at the spedo shop I'll bet he either has or can get a unit that does pulses. All I did was tell him the hole size in the 205 tail cone. Don't all the 205's at least have a hole there for some type of VSS weather it is mechanical or electronic?

seems my statement is false. You want to read the tranny output shaft.


Taken from JTR site :

4L60-E 4X4 APPLICATIONS
A two-wheel-drive output shaft is shown on top. With 4X4 applications, a short output shaft is used, which connects to
the transfer case. With 4X4 applications, the speedometer cable or speed sensor normally attaches to the back of the
transfer case.
The reluctor ring must be installed in the governor area because the ECM would get an erroneous speed signal if the
reluctor ring was located on the output shaft of the transfer case when the transfer case is in low-range.
Installing the speed sensor in the governor gear area requires drilling and tapping a 3/4"-16 UNF thread into the transmission
case.
If you are using an aftermarket transfer case adapter and output shaft, the output shaft probably has the governor gear
as shown above. This requires Stealth Conversions part # 4L60-002 which has an inside diameter of about 1.42 inches
to fit over the governor gear.
The governor gear has a slight crown which requires that the reluctor ring must be installed as shown with the clamp
towards the front so that the clamp is directly over the crown of the governor gear so that it does not slip off.

I would imagine this would apply to transmissions other than the 4l60e as well.

The question I have to ask is, "Is this for your trans in the sig line?"

If so, then why use the 205 sensor at all? Have you checked to see if you can get a vss reading from the rear speed sensor in the 4l80e? 2wd 4l80e's use the rear speed sensor for everything, 4wd's don't use it, and even though the sensor is there, there may not be a reluctor on the planet inside.


Does any of this make sense yet?

Yes this is for my 4l80e. When I first posted I thought I would need one in the np205.

yes makes perfect sense. AFAIK all 4l80e's (wether 2wd or 4wd) have 2 VSS reluctors built into the transmission. The 2wd 4l80e use both VSS sensors. The 4wd 4l80e only uses the front one(front) and has a dummy plug in the second one(rear) There is a 3rd VSS in the transfer case on a 4wd 4l80e. But only the 1st and 3rd are used. And from my understanding the reluctor is part of the hard parts of the tranny. It is not a seperate peice but actually built into the drum(?) I believe. Not 100% sure what part it was part of. I can look it up again if needed though.

And you are correct. I will be able to just use the sensors in the tranny for my setup.

Whoa, hold on just for a minute yet. Ok, so since GM cheaped out on a lot of late 4l80e's, they didn't put the reluctor in for the 4wd's that didn't need it. All 2wd's and early 4wd's have it, and if you are lucky, your four wheel drive case will too.

So, pop out the rear sensor, and look inside the hole now to see if your planet has the reluctor or not. If not, you could swap out the planet, or you are going to have to continue with the 205 vss.

I have a 2wd 4l80e.
