improving shifts... DIY shift kit possibilty?
Ok, so I was looking at the smallcar website at their stage 1 shift kit or whatever they call it. Seems like a good idea and everything. Also, I've heard of folks just unplugging that sensor in front of the battery and that does the same thing, but makes for not the most friendly driving otherwise.
Well, maybe this has been done, maybe not, but here's my idea. Why can't you just cut one of the wires that goes into that sensor thinger and splice in two wires that run into the cabin to a switch. When you want firm shifts, you just flip it (so the circuit is open) and then when you're done you just put it back. That way, the tranny acts normal under "normal" driving, and when you want aggressive shifts, you can have them. Would this even work, does this make sense... Has anyone ELSE done this? Please, if you have information regarding whether or not it will work, please let me know as I'm trying to learn about the car while NOT destroying it. Thanks in advance. peace out homies. -nevin

You will need a resistor across the switch, or you will generate unwanted TCU codes...not to mention the dreaded 16 blinks from the Power lamp on startup...

The thing beside the battery is a resistor. The specific value of the resistance (the numbers of ohms) governs how firmly the trans shifts. Some people have swapped theirs for different rated resistors to get firmer shifts. Your switch idea could work, but as processengr said you'll need some sort of resistor in there to keep the TCU thinking straight.

The dropping resistor has a special function and this does not involve line pressure adjustment. Disconnecting same does increase line pressure, but importantly as a result the designed function is lost. This factor should be carefully considered.
If you go to my locker, you will find information under Transmission Solenoids, which includes details regarding the true function of the dropping resistor circuit.

What is considered a firm shift? Does this mean an increase in power between shifts, fuel increase in between shifts and/or lack of stall time between shifts? There's so much going on in between the shifts that they all seem cumulative to the lag/slow shift. I hate it!
