Direct Connection 727 shift kit

[challboy728]

I had a Direct Connection / Mopar Performance shift kit installed in the A727 transmission out of my 1970 Dodge Challenger. I don't like how the transmission shifts and I would like to take the kit out. I saved all the parts that were removed from the transmission and saved the instructions, however, now I have misplaced the instructions. Wondering if anyone might a copy of the instructions that they could post. Thanks in advance!!!

If the kit is P3690633, the following images show the instruction sheet and an original kit:

The reason you probably don't like the shift is the kit has you crank up the line pressure. What they say to do makes it way too high. You can back that setting off a couple of turns to correct. The accumulator blocker rod and front servo mods are very good. You want the quick firm shift as it helps the trans lifespan. Cranking up the line pressure does not do so.

Thanks for the info. I'll give your suggestion a try. I manually shift it up and down now. If I leave it in D, it immediately shifts into second then third when I start out. Also, the transmission doesn't kick down if I get on the gas.

That is a classic example of the kickdown setup not being adjusted properly. Unless the valve body is setup to be a manual shift only, the kickdown lever provides throttle pressure to the bands/clutches and is vital for the health of your unit. Is the kickdown lever functioning? There are two levers on the driver side of the trans, and the kickdown lever is on top. It connects through a series of rods to the carb so when the carb is opened the lever is pushed back. You might try adjusting the adjusting rod at the carb to be longer which will provide additional travel of the lever at the trans. See if that helps with the quick shifting issue you see. Proper adjustment of the kickdown is vital, and the trans can be damaged if left like that.
