Does Keisler use Mcleod shifters? I"ve seen pics of those and they look pretty nice.

 

 

lol no they do not use McLeod they have there own design.

 

Let me try to answer everyone's concerns here and explain the new PerfectShift3 advantages and how you can get one:

The previous shift design is a two year old set-up that offers nice short throws and a narrow pattern. When introduced this was a huge step forward from the first generation. We have this design in the Keisler Maximum Overdrive Corvette and it has served us and many of you very well.

However, some of our customers have asked for a more positive centering action to shift quickly from second to third. The springs built into the body of the transmission are not strong enough to move the linkage quickly to third, so we went to the drawing board and came up with PerfectShift3.

There are several advantages to the new shifter design:

1. Easier installation - the roll pin that holds the linkage to the shifter is now gone, replaced by a bolt together yoke that makes installation and de-installation much easier. Many of you know that the roll pin is easy to put in and a bear to get out.

2. Quicker more positive shifting - with a simple adjustable spring rate the mechanism can be "tuned" to your desired shift action. This can be done in minutes.

3. Vibration reduction - the previous design used the original cup and ball design from Tremec, which required grease in the cup to maintain tolerance. Over time, some of these cups loosen up causing vibration. The new design uses a Keisler designed graphite impregnated constant grip cup that keeps contact with the shifter at all times. This significantly reduces vibration from being transmitted into the cabin.

This PerfectShift3 is now available on all Corvette PerfectFit models. A retro-fit kit can be ordered for those who would like to upgrade. The install is diy and very straight forward but you will have to do a little wrench work to put it in. My opinion is that it is worth the trouble.

Please call us at 865.609.8187 ext 1 so we can explain the retro-fit and the special pricing we are offering to those who want to upgrade. We know that some of you have some vibration issues and we will want your old one back for R&D. We will certainly take special care of those who have had specific issues with the previous design.

Experience the best shifter to ever grace a TKO. Give us a call.

 

Yikes, what a question. Catch my last post for a full explanation of the Keisler PerfectShift3.

 

So, if the unit for my '64 was shipped June 5, 2006, which did I get???

If the shift tower has a blue anodized finish then you got a PS3. Gray.

 

Wow... glad they figured this out! Keisler, Please see this thread:

You guys were helpful back then... but I wish the vibration would of stopped. It seems ok sometimes and other times it is vibrating a lot. I've replaced the drive shaft with a balanced one you sent out... It is still vibrating in 3rd though. You can feel the shifter handle vibrating in that gear. Other gears seem ok through.

 

The mechanic says that it appears to be a black/(dark gray?) irrodite (but definately not a blue anodize). He's not installed the trans yet and actually had to take it out of the box to see which it was (driveshaft arrived just this week so he hadn't started).

What do we need to do to make this right? You can contact me offline.

Thanks,

I have noticed this many times. A few times while drag racing I have missed the 2 to 3 shift and winged the motor or ground 3rd gear a little. If I take my time it will go in but who wants to do that while drag racing the car. I just stab the clutch and shift. This shifter might help out.

 

I've been through this whole thing, got the Kiesler TKO 500 tranny, wrong slip yolk. They sent the correct yolk. Installed tranny, did the whole bell housing runout thing, and since the first drive, vibtating shifter, unbalanced drive shaft. They sent a new drive shaft (balanced by Kiesler). installed drive shaft. Still vibrates, relocated E-brake cable, got tailshaft centered better, improved drive line angle. Adjust diff pinion yolk, improved drive line angle more. I just keep working on it.

As this continued the vibration has become less and less. The thing shifts and runs as smooth as glass as long as the RPM is less than 5000. From 5000 to 6000 the shifter rattels enough that passengers ask WTH is wrong with the thing.

Keislers customer service has been fair to me, they have always done what they said they would. But with this relentless vibration, how do I know there isnt something else wrong here and if I continue to drive the car that this expensive piece of equipment isnt going to come up lame on me someday soon?

 

This is the same exact thing I went thru,

 

Please give us a call so we can get you upgraded to the PS3! 865.609.8187 ext 1 for sales.

 

The other thing you have to do with any of the Keisler shifters is remember not to force the 2-3 shift. Just put your hand on the back of the ball and slam! If you are moving the shifter in a z-pattern you will hit the 3-5 stop in-between gates. This gets worse with adrenaline and frustration. Take the car out for a few practice runs, put the car in second and slam third. After a few times you will be much more pleased with your track results. I demonstrate this at shows and I am pleased to see the smiles when the light comes on for customers.

All of this being said, the PS3 is quicker to center and more precise and would improve shift quality when you're in a hurry.

 

When identifying the PS3 you will have a blue shift tower, not the stub that the shifter bolts to. You may also, in early cases, have a bare aluminum tower with the Keisler logo engraved in the side. Only PS3 shifters have this engraving. Gray.

 

Was that something I was supposed to know? I do know that it would be odd that so many people had vibration problems with the McLeod shifter. That's ok though......now I know that it's a "Keisler Rig".

 

Does the tranny have to come out to install the upgraded shifter??

 

I started a thread a long time ago about missing the 2nd to 3rd shifts and was asking at that time if anyone else was having this problem, I was bacically told I didn't know how to shift properly

I would never take this car to track the way it is. While I can hit third most of the time, it would be a crap shoot at the track

 

I'd like to know this too... anyone know?

 

Does the tranny have to come out to install the upgraded shifter??
Anyone?
