Ok I got the kit in, and after the stupid manual linkage rod slipped loose during the install and scared the crap out of us (no reverse or neutral)....we got it back in place and took RAIF out for the test run. At first we hung in 1st and 2nd, but finally with a click things started shifting right thru 3 & 4. Common problem so I have read. RAIF is running great and shifting strong in a gears...

So on to my question...in the 1-2 accumulator set up, you could go with 1 to 3 washers. 1 for a lighter smoother 1-2 shift and 3 for the firmest shift. Directions said go with 2 so I did. Not as firm as I would have thought. I want to go up to the 3rd washer...

So what are you guys running on your 1-2 shift accumulator? How many washers? What do you think of it? I think I want to go to 3... Anyone running 3?

I have a 700R4...

I put 3 washers in, and even with my 2600 RPM stall converter, it shifts real firm. It definitely chirps the tires between 1st and 2nd.

curt86iroc

i believe i also have 3 washers. shifts nice and firm and fairly hard.....

I have three washers in and my car lays about 5 feet of rubber at the transition from first to second...

With three washers installed, how are your 1/4 throttle to 1/2 throttle shifts? Firm?, Very firm?, Extremely firm?, and what torque converters are you using on these units?

I would be very interested in that info as well.

I used 2 washers and my shifts aren't that quick. I do have a Vigi 2600 though. Maybe that accounts for the semi-weak shifts. Is the 2-3 shift "adjustable" as well? I seem to recall something about the washers in the servo on the side of the tranny case.

GMTech

The higher the stall converter, the more it "asorbs" the shift feel. As far as the washers in the servo, TransGo uses those to adjust band clearance. It does make the shifts a little firmer, since they replace the servo cushion spring, but added/deleting washers doesn't adjust the shift firmness, only band clearance.

Acceld Z

Is their any way to adjust the 2-3 firmness? I plan to add the 3rd washer to the 1-2 accumulator.

Pro Built Automatics

Changing feed hole size in the plate will change firmness. Installing more quality clutches in the 3-4 clutch pack will change firmness. Adding the Corvette servo will change firmness. Changing the release hole size for the 2nd gear band will change firmness. All these can or will change 2-3 shift quality.

I was under the impression that the commercial Transgo kit(the one with the video) came with the vette servo.

SSC

The shifts were alright but not firm enough with 3 for me so I used the B&M accumulator HD setup in the accumullators. Shifts nice and firm but not to hard like some other I have driven.

Edit: I still think firmer accumulator springs are the real answer, washers are cheezy.

Thanks for the input you guys...I will plan on adding the 3rd washer. We planned on adding a chrome pan anyway...

My 2-3 is my best shift after installing the kit...but I only have a 2.8L and I don't have an aftermarket torque convertor yet. We are planning on having one custom made this week with a 2800 stall. I know its a 2.8, but we have it cammed, heads & intake are ported, all the free mods, larger injectors, and a custom chip... and soon long tube headers...

For future engines....I plan to go to a 3.8 turbo motor (GN or TTA) as soon as we find decent one, get it ready, and I can get my 82 done, so I will have a car to drive while mine goes down!

I used a TCI rebuild kit with the trans go shift kit. Corvette servo and a few other goodies, and the car kick's sideways every 1st to 2nd shift.(still have rebuilt stock converter though)

Pro Built Automatics

Working with the 1-2 accumulator is the best way of changing the firmness, not blocking it. There are several ways to change firmness on the 1-2 shift, you can keep the fairly smooth part throttle shift and have the shifts get firmer (progressively) with more throttle by changing springs, hole sizes, and changing the spring in the accumulator or the accumulator itself (the one in the valve body), this is assuming you already have the Corvette servo.

Acceld Z

Is the corvette servo an upgrade over the servo assembly that is included in the Transgo commercial kit that is sold by places like Summit?

redraif

I would like to know the answer to this too...

Acceld Z

I was under the impression that the servo assembly included with the transgo kit is a generic corvette servo

Chris Etemadi

There is a guy that is willing to build me a 700 he said it would include... Borgwarner clutches, corvette servo, superior shift kit, 3-4 wot valve bigger boost valves. and somthing else I have never heard anyone of talking about. I belive he said that instead of springs he would install pistons? HE said it would firm up the shifts alot.
Also he was talking about something that would firm up the 3-4 shift. does anyone know what he was talking about?

25THRSS

I think the servo in the transgo kit is the exact same thing as the corvette servo.

Pro Built Automatics

Chris Etemadi, putting in pistons to replace the springs on the 2nd gear accumulator will produce 1-2 shifts that are very firm (if not violent) at light throttle openings. The main reason that people do this is they "do not" understand accumulation, if they did they could get "best of both worlds" in their 1-2 shifts. As for the Corvette servo, it does not matter if is generic of OEM, they are the same, only difference is price. As for the Superior valve body kit........

Acceld Z

Is there a an upgrade over the corvette servo? What's the "monster servo" i've heard about?

ZaphodB

I only have 2 washers, but my car lays rubber and goes sideways on the 1-2 shift if I get on it...

Could have to with both the Shiftkit and the Supercharger. But the car got much more fun after installing the shiftkit.

Conclusion: I am happy with 2 washers in the 1-2 accumulator.

91wtROH17's

Ya, I'm guessing the supercharger has something to do with it!!
