Hello ,

I have a hydro 400 Transmission . 
1St to 2nd gear shifts at 40 k thats okay 

2nd to 3rd shifts at 80 k which is to high 

I would like to lower that to 60 k 

which spring would I use to lower the shift point (colour of spring ) 

thanks 

A quick look on line found me this,

And from what I understand, the primary adjustment is in the weights. Lighter=Later shifts, with the springs fine tuning the points. I always thought my 400 was awfully early with the stock governor, but I just got used to it.

Not sure if these are the universal spring colours in general use.

I AM NO EXPERT 

But what I learned while adjusting mine is a few things

1 whatever you adjust on the governor ( weights or springs or both)

it changes BOTH shifts 

You can buy a kit 

or you can adjust what you have 

using 6d nails to replace the pins

the hard part will be finding springs without buying a kit

lots of info online

Thanks Mark for you information 

stay safe 

Couple pics of my before and after

And buy an adjustable modulator.

Hello 

thanks for the pictures,

I will change the springs , what spring did you use 

did it lower the shift point or increase the shift point 

thanks 

Hello 

I do have an adjustable valve , I adjusted it and it did soften the shift .  The hose is good I checked it

Thanks for the great information,

 Which is before, which is after?   It looks like one is blue (or maybe purple), and one is green.

I see a heavier weight with the same spring, lower image.

 Now that I'm on a different device I think I see the same thing.

Sorry for the confusion 

top pic is the modified inner weight

springs were never changed

Also this governor is for a turbo 350

But from what I understand the part is the same

only difference being the gear on the end and the fact that it

rotates in the opposite direction 

Hi Greg 

Thanks for the information 

I will just have to play with the springs to get a good shift point.

great information 

stay safe
