Ordering the vette servo, I notice they have a long pin kit and then a kit with just the servo(which I assume uses the stock pin). Which one is "better"?

 

although i have a built tranny, when the tranny was stock i only had the vette servo with stock pin

 

any idea what the difference is? It's a $15 pin, surely it does something? lol

 

couldn't tell you. maybe some more people will chime in...

 

The longer pin is to reduce 2-4 band clearance for a "supposed" quicker apply. A pin that is too long will cause the band to drag and burn up. Realisticlly speaking, 80% of my transmissions, the stock pin is just right.

 

So you're saying that the long pin could be the incorrect pin for my tranny? On the other hand, does that mean that the short pin could be wrong and the long one correct? Excuse my ignorance....

 

Correct. Odds are, that pin will be too long, but it could be just right. Usually when I sell servo's, I include band adjustment shims (from the TransGo kit) at no charge, so if your current pin is OK, discard the shims and if its a little short, then use them accordingly.

To know if the pin is the correct length, assemble and install the servo minus all seals. Put the cover and snap-ring in place and measure the travel of the servo cover. The cover should have between 1/16" and 1/8" travel. Once correct, dissasemble and install all seals and reinstall.

 

Well to support the business of active members here........you wanna sell me a servo kit with the shims you mentioned or will that come with the HD2 kit when I order? I was just going to order the servo kit off of ebay from OPT, but if you have the kit and are willing to sell at a comparable price, I'm game
