Kickdown band lever ratios

Not necessarily. It's all in the combination. As long as you have enough springs in the front clutch, 2 springs (or 1 real strong one) in the front servo, and the front clutch clearance isn't too tight you should be ok. Seen many that were ok, but also seen some that aren't. Hopefully it doesn't overlap because that's real detrimental to a trans. It's really not too hard to change a lever if you do have problems. Just drop the pan and VB and take off the torque converter cover and you can use a 1/4" drive ratchet and extension to take out the plug that leads to the lever pin. Then slide the pin back just far enough to get the lever out and the new one back in. Hopefully you don't have to worry about it

Thank you Tracy! btw.. My 340 is almost done.. probably 3 wks out. But I have a long way to go on the body. If all goes well I'll let you know how it runs in July 2014. :D
