Part # for largest stock 2004R intermediate Servo ??

[88S10Durango]

Hi all , using a generic 2004R , I want to upgrade to a stock GN servo for 2nd gear ,they gotta be larger than whats in mine ,when I order one from what year GN and whats the largest stock one to use ?? Is there a stamping # on the servo or cover like the Vette ones for the 700R4`s ,, I`ve blocked my 1-2 accumulator and want to do the servo next ,, thanks Bill,,:smile:

I believe there is a TH200 that is preferred by Chris at CK. It is the largest with an actual GM part number but is usually procured at a 'recycler'.

PTS, CK, and Sonax have larger after market units that are larger than any of the GM(Hydramatic) parts.

Are you using one of the HP valve bodies? I am made to understand that not using one can affect shift quality.

You can get excellent shift quality from any VB.
The GN servo with a 694 cover is the largest stock 200-4R.
The TH200 servos will work but they are hard to find.

I have stock GN servos if you need one.

servo

thanks guys the 694 answered my question , this is for my daily driver ( 88 S10 pickup + V8 ) and I`m only running about 225 Hp at the flywheel , I have a shift kit in it & the 1-2 mod ,I checked out a Sonax Super Servo here ( Canada ) but I refuse to pay $ 389.99 for it ,I think that large of a servo would be overkill for me anyway , the only other one that I liked here was made by Shift Technologies ( Superior ) and it is $ 114.00 here ,my tranny shifts good so I just want that little extra bump in the 1-2 & 2-3 shift , Jakeshoe out of curiosity what would you want for a stock 694 , with the 694 will I need to get a piston to match & pin or could I use my stock one ?? I think the shipping to Canada would be ridiculas in pricing but mayby not ,, thanks again Bill..

Arghh Canada shipping.
it's not really expensive but it takes me an hour + to do all the paperwork here.

The servo would be $60, it has a piston, new seals, etc, you just use your pin.
Shipping would probably be $20-25.

Do this,
Check with CKperformance's Canadian supplier. I think it is on his website. They may have one in stock.

The Superior servo is a decent piece. Not as big as the Sonnax but fine for your application.

If you can't find anything let me know.

Thankyou again ,I`ll do some checking on this side and get back to ya later this week ,, Bill

Hi ,, Jakeshoe found this billet super servo at a performance shop next province over from me , they mill them right in their shop ,, $ 95.46 canadian for me with free shipping to my door ,, my ? is will I have to get another piston & pin & spring to match this one as it doesn`t come with either of those 3 parts ? Can I use my stock piston and pin with it ,, it`s a really good price for out here ,, but if I gotta spend 10-50 bucks for a piston setup I wouldn`t buy it ,,thanks Bill ,, It comes with new seals ,,

 

[jakeshoe]

You should be able to use your pin. Check band clearance.

 

[88S10Durango]

Thanks again Jake , I have to wait till next Thursday to order it & will let you know how things work out ,, Bill

I'll start a new thread for this subject.

Hi TexasT I am using a 2004R out of a 1983 Olds that had a diesel engine in front of it ,pretty much a no name valve body ,I believe it was a OM code , anyways I changed out the line bias spring ,the presure reg. spring ,drilled out 3 spots in the separater plate , when I`m into the WOT it shifts out of 1rst at 4800 Rpm now ,, before it would shift at 3000 Rpm ,, I was after gas milage in my truck and the tranny now shifts as par what I wanted other than I want to get a very distinctive firm shift next thus I am going to be putting in a different servo next ,, Bill

Hey Jake, I'm curious, because when I buy stuff on ebay, some sellers moan about the 'paperwork' too. I'm just curious as to what you have to do. I have shipped stuff to the US a fair bit, and the only extra step is to write on the form: what it is, how much, weight, where it was made and if it is a gift or not. It literally takes less than 10 seconds. What are you guys having to do that it takes an hour or more?

 

[jakeshoe]

You have to fill out a Statement of Origin form, another certificate, and find the classification numbers and the site is a PITA to navigate.

Plus all the normal shipping stuff.

If you did it daily and had a good resource reference to know the classification numbers it might not be so bad.

I usually use UPS and it is just a PITA on theirs and the Fedex site to navigate.
It helps though because the forms are mostly automated.

Plus the brokerage stuff. I shipped a 4L80 up that way a couple of months ago and that was a hassle. Customer paid the brokerage but I had to have a broker setup before hand. So it was a lot of delays and back and forth trying to sort it out.

 

[Firechicken]

Ahh I see, it is a UPS thing. The post office is much less hassle.

What Ever Happened To Ck,s Billit Servo,i Hardly Hear Of It

 

[jakeshoe]

They work great

I've used several now.
I don't think you could get a bigger apply area.

Hi once again Jakeshoe , yesterday my truck was taken in and they pulled the valvebody and accumulator , the checkballs were all put back in and the 1-2 accumulator was blocked off as I requested , put all back together ,feels like a totally different tranny now and am happy with it ,not going to put a servo in now until spring time , so I won`t need one of your GN servo`s ,, thanks for all your help Bill..
