Has anyone installed the recent shifter upgrade that supposed to eliminate vibration? If so, how difficult was the install and did it work?
Thanks.

 

several of us have experienced vibration in the shifter at specific rpms. Keisler is shipping upgrades to resolve this.

 

First I have heard of this can you go into more detaill about the vibration problem and what the fix is regarding the shifter ?

 

In my case, after replacing driveshaft with one balanced by Keisler, replacing flywheel with a new one balanced to 8,000 rpm and correctly aligning tailpiece and differential, I still had an irritating vibration in e shifter from about 2750 to about 4000 rpm in all gears,

Keisler shipped me a replacement shifter of a different design that is supposed to fix things.Haven''t installed it yet.

BTW, I have a 383 with keisler 5 sp and 3.08 rear.

 

What do you mean, the shifter lever, handle or ?

I have a vibration at 3200 to 4000 RPM but only in 1st and 2nd

 

I want to see this shifter,I might need one too!

 

motor head,
My vibration is felt anywhere along the shifter shaft or ball. According to Keisler, it's a shifer design problem, not a trans problem. I'll find out this week when I install the replacement.

 

I just emailed them as soon as I read this. I to have had a vibration through the shifter as you others. I have also checked everything out. I emailed them ealier this year and they seem to act as if there was no problems. It shifts great no matter how hard I drive it, but has a rattle like vibration around 2500 to 4000rpms. Seems to go away once I am in overdrive at 2300. thank you for the info

 

Mine has been in the mail since June. I've also never got an answer as to why they sent me two AFU cross shaft ball studs with manufactured bad threads. They have had them since May when I shipped them back for them to inspect.

Did you get these directions? I could not stab my 383 on the front the TKO 600. so I ended up pulling the tranny and installing my motor first. It would have been the perfect time to do it if i would have had the new shifter.

These directions seem pretty straight forward. The time is the tranny R&R. i managed to get those upper two out of the 4 tranny bolts with a thin wall 3/8th drive with a swivle extension and rachet with an angle head.


You will need to drop the tranny and remove the 6 bolts from the base plate that the shifter tower is on. You will see the shift dog that is on the shift rail. Very carefully drive the roll pin out of the dog and be careful not to let it drop into the tailhousing or you will have to seperate the tailhousing from the main case. Slide the dog off of the rail and you are going to replace the dog and the link that goes back to the shifter assembly(the link where you have to drive the roll pin in to hold the shifter stub). The new shift link doesn't use a roll pin, it is actually a 2 piece link that is bolted together using 2 allen head screws. The new link also uses a carbon impregnated cup that actually has a lip around it that grabs hold of the ball of the shifter stub. The new cup and the fact that you use the allen head screws is going to take all of the "slop" out of the equation.
When you receive the new pieces, please call or e-mail me if you need further explanation and I will be glad to try and explain it better.
Hope this solves the rattle problem for you.

 

Must be like a stock shifter I got for my T5, there is nub off the shifter than an extension is bonded to it with a rubber medium to isolated the vibration

 

We just returned a "defective" flywheel that was part of their "over-drive" package. We couldn't mount it on the crank register. Someway, somehow they managed to make a "square" hole. Haven't got a clue how this occurred? At this point I hadn't opened the box the clutch was shipped in yet. Showed the customer the first problem, the flywheel, and he had to decide on a repair or return. He chose return.

Customer dropped off another brand of wheel (no problems here) to balance for his existing unit along with the pressure plate from Kiesler. Upon inspecting the clutch at this point I instructed the customer that I wasn't getting involved with either the original flywheel OR the original clutch. No "safety" factors built in on any of their parts from
what I can tell, even the bell-housing.

I've placed a photo of the clutch he brought in to balance. I told him to take it elsewhere. Thanks, Gary in N.Y.

P.S. This flywheel/clutch ***'y was going behind a 500HP unit, so I explained to him he was taking too much risk with his "limbs" to run any of the pieces. The new flywheel did have an "SFI" sticker, but as I said neither the "bell" nor the clutch was approved. I was really surprised when we took the clutch from the box. You'll see by the photo! We are really getting fed up some of the "quality" of some of these components, we feel the many of the manufacturer's can do much better. Please don't read this as vendor bashing, but we want no customers getting hurt from parts we've worked around. There's already a large element of risk just by the nature of this business!

 

This is not A DESIGN PROBLEM but rather an updated design on shifter assemblies.
Because we did not engineer this newer design to be sold as an after the fact part, my engineers thought it better to write explicit instructions on how to install the newer design. I have been in touch with 6 of you members regarding this update and we are actually including a few more parts besides the pieces we originally discussed(hence the need for instructions) It should be ready to ship this week.

Does this mean that Keisler is going to recall all of your vibrating shifters???

 

Don't get on them about the stock looking shifter. It was just solid shaft made to look like the real thing. It was not designed as an isolation vibration free unit

 

Very interesting...shifter vibration....a Keisler upgrade to the shifter...but not a design issue ??? I'm getting confused with how all this is being explained...not bashing here,but I follow all these questions/responses......

 

 

GKull,
The stock looking shifter is great. Apparently the vibration is coming from the manner in which the shifter shaft connects to the trans. The fix includes different fasteners to prevent the vibes.

 

Richard:

Which do I have (was shipped the week of June 5th)? Is this even a concern for my '64? If there is an upgrade, now is the time to do it while the mechanic is putting it in. I would hate to have to pay the labor to change it, if it can be avoided now during the initial install.

Thanks,

Todd Brody

 

I did not word that right. Keisler actually out of the blue contacted me and several other TKO600 users and said that they were sending these vibration free new style shifters. I thought it was a very nice jesture.

Yes, the original design was functional solid and in the correct position for our C-3 consols. It just vibrated. I've had the pleasure of driving a few circle track cars in my life. Those big straight cut gear boxes are so loud that you can't hardle even hear anything over the gear whine next to you. So i might not have liked the vibration, but it is nothing compared to other big transmissions.

 

I just got my Sept. issue of Corvetter Fever today and it contains an article on installing a Keisler 5 speed. It has pictures of the new "redesigned" shifter. Looks more solid than the old unit I have.

Will all us previous customers be sent a new unit?

Ralph.
