Just posted this on another thread, may as well update here as well.....
Bought a new Bosch GT40r coil and fitted it.
I had my TPS off today, gave it a good soaking in WD40 (sprayed in every gap I could find), and cleaned it with a 'modified' soft bristled toothbrush and dental pik. Let it drain and dry out, and put it back on with a slight adjustment. All the connections got a spray and good clean as well.
Holy crap, what a difference it made! So smooth between gears, and smoother to drive in general. TC still not locking up, but so much better.
Going to book it in with my gas guy for a decent tune-up, and then I'll start pricing reco-ed TC's. Definitely gonna get an oil cooler for the transmission as insurance for the future.
