just thought id comment on shifts are the HD2 kit was installed. First off my tranny guy says that its tired and will need a rebuild soon. He installed 3 washers to compensate for the "tiredness" and left line pressure up. Man im not liking the shifts from 1 to 2. Really hard and not to my liking. Anyways comments are welcome and TIA guys!

even with a "tired" tranny?

Another problem could be if he installed the 1-2 accumulator valve sleeve upside down in the bore of the valve body. By doing this it blocks the circuit for the accumulator and the result is very similar to what you have described.

Start by getting at least two of those washers out of there. Then you can check the accumulator valve while you're in there. And it's always been considered a no-no to have your line pressure jacked up in addition to a shift kit install. If the shifts still seem harsh after doing the first two items, I'd go back to a factory line pressure setting - at least on the 1-2 shift.

Personally I dont use any washers in the accumulators, 1 may be aceptable however but three is too much IMO

I never use any on my builds or in my modified TransGo Shift kits. Having firm to very firm part throttle shifts will shorten the life of the transmission. It does nothing for longevity.

When you say sleeve are you talking the piston in the accumulator tha goes into the cylinder? It goes like this Accum housing-spring-piston?-spring-seperator plate. The reason I ask is because I just put in a transgo kit and removed ALL of the washers I just have the spring and cup with the piston tuned upsidedown (as per insructions) and my 1-2 shift is a little too hard for my tastes.

As a note this is in a '03 S10Blazer with a 4.3L V6 and I think part of the problem is I don't have enough power to turn/chirp the wheels on the 1-2 shift (well right now at least, I'm working on an eaton Blower for it) I initially had 1 washer and removed it last weekend and while not as harsh it still is harsh. Another contributing factor is the 285/40ZR18 KDW's I got hanging out back, just too much traction at the moment.

I would appreciate any advice you guys can give.

Oh and it also has a Vette servo installed.

so you guys suggest that i have the washers removed? what about the "tiredness" of my tranny...i guess i should be lookin at a rebuild soon??

If the Line Pressure Tables were modified in the Tune, then all of the adjusting of shims will most likely not help a harsh engagement. Those tables need to be set to stock in order for the new mods to do their jobs properly!

If it is tired, he builder is referring to clearances... clutch pack clearances, bushing clearances, pump clearances etc.....

It sounds like it would be best to begin to plan for a well built unit now, rather than trying to scramble for a replacement unit when and if it fails.

Good Luck with it.

same thing my tranny guy said. so with the rebuild, i guess all tranny settings(except for shifting pts. and torque management) should be set to default or stock?

Better to leave all springs, and washers out than to install 3 washers= same thing, less trouble.

There is little difference in 1-2 shift quality between the 1-2- or 3 washers. The biggest change comes with the apply orifice.

Check that the 1-2 accumulator regulator spring isn't cocked in the bore!

In my experience 1, 2 or 3 washers completely owns the 1-2 shift quality. Better to go with no washers on the 1-2 accumulator as the re[lacement spring is already firmer than stock to start with. Any shift quality can be bumped in the tune due to the extra available line pressure after the kit going in.

I've had my out valve body out 3 times after I installed the shift kit and I found that doing exactly as the instructions say for feed hole mods is perfect. On the 2-3 hole I went way too big and my ECU set the car on limp home LOL

No washers would be the go, 3 is too extreme IMHO

Personally, I have one washer and I really like my 1-2 shift quality. With an aftermarket stall, you may want to increase your shift feel a little bit. Especially with the SY3500 which is known to feel pretty soft. But I wouldn't go more than that.

yeah im starting to think my SY3500 is alot softer than most other stalls. I think this is where my tranny guy felt the soft shift and tiredness feeling...... thanks RevGTO

What size feed hole for the 1-2 shift did you drill the separator plate too? And whta color spring did you use on the 2nd gear accumulator that is in the valve body? Red or White?
