Transmission Mods

[Huskymaniac]

I have been doing a lot of reading and have attempted to compile a list of transmission modifications. I don't want to start an argument but I would like to get a list of mods that will help prolong the life of the transmission and rank them in order of their effectiveness. I am not concerned with feel or improving the 0-60. This is strictly reliability related but, of course, anything that improve both would be great. Here is what I have so far:

1. Transmission cooler
2. Transmission filter for post 1993 models
3. Upgrade valve bodies
4. Upgrade TCU with unit from ecutune.com
5. Harvey's quick change
6. Shift kit from smallcar.com
7. Remove the transmission resistor
8. Increase the resistance of the transmission resistor to 20-100 Ohms
9. Add switch to engage power mode
10. Switch to synthetic ATF

What are people's feelings about these? Which will help reliability and how would you rank them? I have read that removing the resistor or using the shift kit may actually hurt reliability. The power mode switch will change to the better shift maps but doesn't it also prevent torque converter lockup and doesn't that actually cause more heat to be generated? It would seem that the effects cancel each other at least somewhat. I'm not sure what Harvey's quick change does or how it is installed. The TCU upgrade would seem to change shift maps while still allowing lock up. It also forces lock up and sets off the warning light at a lower temperature. I don't see a drawback. The bigger valve bodies seems to be a nice upgrade but complex and expensive.

If the tranny cooler is installed between the condenser and the radiator, does it matter exactly where? High or low? Passenger side or driver side? Does it need to be attached to the radiator or is the sandwich force between the radiator and condenser enough to hold it, especially if it is a small one? Does it need to be cushioned or insulated from either?
