700 r4 shift kit

Ok, I got the 700r4 transgo kit.

I want just a little more. Can I leave the springs out of the accumulator beside the valve body and the springs out of the servo/accumulator beside the dipstick instead of using the stiffer(blue) springs?

Also it did not say anything about changing the springs on the 1/2 & 2/3 shift valves. Can I stiffen them to increase performance?


-Thanks

Cool

stiffer springs on the shift valves will only change the shift points to very late.

You do not change these springs for performance.

It only takes "ounces" of a change in tension on these springs to alter the shift timing of the tranny.

If you are wanting firmer shifts , changing shift valve springs is not it

Thanks Crosley. I have a feeling I'll have the VB out once the trans is in the car to fine tune it. Luckily it is on the bench right now so it is easy to get to.

You say that the shift valve springs alter the timing of the shifts. I'll remember that.

What about those accumulator springs? It seems like there should be a lot of room there to work. And there was another two springs across from the 1/2, 2/3 & 3/4 shift valves I had to put stiffer springs in. Can I leave those out...or stiffen them up to increase firmness?

Any tips would be greatly appreciated on top of the help you have already given. Thanks for your help.

Well since the other post with the link talking about 700Rs not being able to shift solid was locked....


Is that why nobody has told me how to make this trans shift like I want?

Hello Crosley,

i am looking for very firm and positive shifts
in the 1/2 & 2/3 area.
The 3/4 is not really a lot of concern b/c I probably will not be giving 3/4 full throttle upshifts.

I am not exactly sure of the year 700 but it does not have the aux. accumulator. Also it is the 30 spline input shaft. I'm not sure if you need that info but....

Thanks again for your help.

TransGo Kit

Follow their instructions and video exactly and you will be fine.

Example:
Step 3: 2nd Accumulator Discard original springs. The SPACERS adjust the 1-2 shift firmness:
Full Race and High Stall converter use 3.
Very Firm street and strip use 2.
Crisp to firm use 1.

Clearly TransGo spent countless hours and dollars developing one of the best kits on the market. Why would you buy a $120 kit to think you can improve on the package they have developed. Why try to mix and match parts when a proven kit will do what you need? Unless that is, you are trying to shift so hard you break parts and require neck braces be worn by passengers (lol). Maybe you should consider the "Stick Shift" option? But then you will need to have them sign a release form before getting in your car. IMHO, you will be making a big mistake to even consider deviating from their instructions. Best of luck, Ed

Cool

OK, you have a late 1987 tranny unit or newer.

Which TransGo kit? Does it contain the mentioned accumilator spacers and springs or did you buy a Jr Kit?


Do you have a vette style or billet servo for the 2 - 4 band? This will firm up the 1-2 & 2-3 shift


Did you buy a larger main boost valve? A .500 from TransGo or there is a .570 valve availible.

There are 2 boost valves, low & reverse and the main

Thanks Crosley.
I've been biting my tongue for quite awhile on this one.
