Tko600 Warning!!!!

[Excaliber]

The misalignment may or may not acutally be a problem, THATS what were trying to find out all right.

I guess another question is: Is this typical for all TKO's and within specs (3rd gear alignment thing)?

I’m not sure I agree with Jeff. Again, looking at a picture makes it difficult, but if the countershaft gear is setting forward of the main shaft gear as it appears, the countershaft gear will exert way more force on the forward edge of the main shaft gear. This is the problem of an off set and what you see in the failed gears. The teeth start to fail at the forward edge of the main shaft gear and the destruction continues until the teeth are gone. I don’t think only looking at the contact pattern in the middle of the gear tells the whole story.

Because the teeth are at an angle, the front leading edge of the tooth will engage first and as the gear rotates, the force will distributed towards the middle and then rear edge of the tooth, so the loading of the tooth through rotation is kind of complex. At any given time, one tooth will be loaded on the leading edge, while the tooth before it will be loaded in the middle, and the tooth before it will be loaded on the rear aspect of the tooth. I think a mechanical engineer with a background in gear design, transmission, would be the real person to get correct info from on what are the main factors for gear failure in this case scenario.

Greg do everybody a favor, Call G-force and send the trans out for there blue print job!!! Old school, gears should be parallel to each other with main contact spot in the middle of the 2 gears. They now set gears to drive into each other with one being a little head of the other. The play in the shafts, and the air gap between where the gear are engaged are the most important thing. I am no KieslerNick fan but they have given out more help than alot of other companys. Break a motor and take it back to the machinist and see what happens if the bearing are spun, It's all yours 98% of the time. Kiesler Nick Nick I can but a 1K motor to the back of any "stock trans" and it will live for some time. There is a Viper running 8.0's with a STOCK trans but read a little farther down and find that the trans went to G-Force for a blueprint job. I think the your company has helped Greg with his problem. There are too many trans specialist NOW getting into this thread. I am backing out. Nick maybe down the road Tremac should have a trans school like FORD and GM for building trans for racing or blueprinting. Just a thought Rick Lake trans schools for GM 31,5-6 speed trans rebuilt 4, came back blownup 2, putting the right trans application to the right motor, pricless. Clutches don't count

I wouldn't assume Fordfan69 got 'hosed on the price'. The custom PACKAGE he bought which included more than just a trans, may be a reasonable price. The issue is the trans failure, not the price paid.

I just did my trans swap. I talked with Jimi maybe three or four times and got all the "Special" parts I needed to make the exchange. It didn't cost anywhere near what these guys changed.

Ernie, I am not sure what was really delivered to the victim, so you may be correct, but I believe he could have done better by shopping around.

I probably will not buy anything from this Keisler organization for at least two reasons: 1) I would not know if I am getting hosed on the price. 2) I would feel I was abandoned if the item sold to me failed in anyway.

Just my $0.02 to a very long thread.

Sometimes it's better to 'sole source' a product and it's accessories to avoid the hassle of 'shopping around'. Generally speaking you will pay more if you do this. Tech support can be invaluable on occasion. I've found you can ALWAYS get a better price AFTER you've built your whatever.

The sales, the 'what if's', the new really good sources are endless in hindsight! And now that you've 'learned' perhaps you don't need that 'technical' support as much as when you started. Tough call when and where to buy.

[flipper35]

For what you get the price isn't that out of line considering it is a complete package to install in his Charger. When they first started with the TKO II they would even relocate the shifter to fit the stock console. I don't know if they still do, but I would think so.

Forgot about this being in a Dudge.
