Anyone running keisler 5 speed. Seems very hard to get gears at high rpm's.

Call Liberty gear and ask them ,I think they can modify the shift rail to cure this issue .

my uncle has a keisler 5 speed and says he dosent linke how it shifts either.

From what I gather, that's the nature of the beast when running a TKO transmission. I had one that I did NOT get from Keisler, and it was the same way. casual drives around town, I could shift it without the clutch with ease. under light driving, I could clutch it and shift it fast. give it WOT and try power shifting? yea, right! Aint gonna happen!! couldn't even shift it fast by lifting off the gas when shifting.

some guys claim that it's the trans to crankshaft run-out, and that the bell housing is not dialed in.

but, can there really be THAT many people with bells that are out of spec, even after dialing them in? Me thinks it's a TKO problem.

Bulls---! on the bell out of alignment. spent couple of hours to make sure it was nearly perfect. Got offset dowels to tweak it a little to get it true. Like you said, really nice driving around, but as soon as you get into it a little it turns to mush. I don't race and cannot see how you could because you would miss a lot of shifts.

I had a TKO600 and it had a hard time powershifting into 3rd. Seems its a common problem with the TKO. Look at Keislers website and how they advertise their new trans.."no more missed shifts".
In my case there was no ryhme or reason as to why, sometimes you could powershift into 3rd sometimes you couldn't. I'll be buying a new Passon trans once they go on sale.

My TKO 600 has the same sympthoms. Hard to shifts at higher rpms - all gears. It usually don't miss shifts, but won't shift fast.
Rechecked bell runout three times an it's dead on. Verified no clutch drag. My trans also make a notisable whine, mostly in 4. gear and has always been this way. Hopefully someone has a cure. Has anyone had any work done to their TKO at Liberty gears?

General: Yes, it is more of a "WILL IT EVER GET IN GEAR?" than a missed shift. second to third is the pits. It feels like mush.

Mine would whine in 5th.

My understanding of the problem is that its something in the shift rails and yes Liberty has a fix for like $300 if you send in your rails to them.
I wish this would become common knowledge as I have the tools and exp to fix mine if I just knew what they did.

Just how fast, fast is, is somewhat subjective. My experience is that mine is a bit better than some have described it, but I know it's not on a par with the 833 I raced with in the late '60s. I've never been brave enough to attempt a true high rpm power shift ie. no lift, which I did regularly with my Hurst Competition Plus 833. "E" bodies are probably a little worse than others due to additional external linkage. I've yet to see extra linkage ever improving shift quality. Three of the major factors affecting shift quality are the rigidity of the linkage, synchronizer design and condition and clean clutch release. FWIW when I want max performance I shift at 6200 rpm. I lift [ briefly ] and I keep my clutch properly adjusted. As others have noted at lower everyday rpms shift action is easier and quicker. No doubt the Passion 5 speed will be an improvement. Probably Keisler's new tranny shifts better as well. The thing is without the Keisler TKO I would have had to wait at least seven years to enjoy the benefits of overdrive. Back in the fifties with very few exceptions we had to make do with three speeds. The sixties brought commonplace four speeds. Now high end cars have manual transmissions with paddle shifters. Progress sometimes just takes time.

i have the tko500 in my car and i love it, i'm not a spokes person for keisler. i have had the tranny for 5yrs now and except for some leak issues, which they fixed at no charge it's been great. i have no problem from 2nd to 3rd, power shift or otherwise.

what is different internally from the TKO500 to the TKO600? I had the 600 version behind my big block, since I knew it'd be making north of 500 lbs of torque.

I wonder if there's any correlation to who loves their TKO and who can't shift their TKO with the 500 and 600 versions?

Don't get me wrong. I love having the over drive. Have 430 rear and can go 65 at about 2200. Also, i am not talking about shifting 7000. I am talking about 5500 to 6000. Running 6000 chip right now. It's like when you are going from 2 to 3 the trans does not know where 3rd is located. Not a missed shift.

I granny shift my tko-600 at 6000rpm with no problems. Mike

2-3 is not an easy shift with the TKO 600. Higher rpms definitely make it more of a challenge.

I've installed one of the new RS500 trannies. Seems to shift better than their TKO offerings. It wasn't my car so I can't vouch for the 6 grand shifts, but gear selection did feel more direct and positive.

I was able to shift My old 833 a whole lot faster than my keisler. I miss it sometimes. The OD kind of makes it easier to live with, but I'm not totally convinced I made the right decision.
