got it back 2 the trans shop and they got 2 washers out so i only have 1 in there with the servo and it still shift hard ( barks the tires at 1/4-1/2 throttle) almost just as hard as it did with 3 washers

so i called WFM 2 see if he can tune it down a lil and he said that he dont like 2 do that 2 go back 2 the trans shop and get the other washer out
and maybe take the servo out

i dont know what 2 do

How big did they drill the holes in the seperator plate?

he said the max

That's probably the reason right there.....get another transgo plate and drill the holes to the smaller of the two sizes. The larger is for applications with a high stall converter. Try that and leave the one washer and the servo in.

At first I had 2 washers in and it shifter really hard-barked the tires @ half throttle. I took all the washers out and it shifts a lot better. I have the holes in the seperater plate drilled the smaller size. I also have the vette servo with a longer pin. I hope this info helps you out.

Mr. Sandog

There are at least three physical modifications in a shift kit affecting the 1-2 shift:
1) Number of washers
2) Size of hole in separator plate
3) Size/type of accumulator spring

I know of someone who had issues and wasn't happy until all three components were returned to stock. It is much easier to program a soft shift into a firm one than it is to tune down a harsh shift into a softer one.

Personally, I put zero (0) washers in the accumulator and it was still kind of harsh, but I was able to soften it up with programming. I've heard that if you don't have a high stall converter then you don't want any washers in there.

Don't forget, shift kits were made to be the only modifications to be installed, so if you are installing a Vette or billet intermediate servo, you are also firming up the shift, so this compounds the issue.

My recommendation for installing the Transgo + Vette or billet servo in a truck with the stock torque converter and no other programming, is to drill the smallest 1-2 hole in the accumulator plate, and put zero washers in the accumulator.

If its still electronically controlled you can reduce the pressure alot with the tune, tell your tuner to use the pressure modifier table for the 1-2 it works well.

Mr. Sandog

Actually, that's a good point - you can also modify (lengthen) the 1-2 shift timing, which is what I did to fix my problem. If you have access to programming tools, this is a little easier than digging into the transmission again, but you may not be able to avoid getting dirty again.
