I just went to an automatic transmission specialist here in the Philippines.
He recommended that we change the 1-2 and 3-4 shift Solenoid because he said that this is the most common part that gets problems. Labor here is relatively cheap (about USD60.00 equivalent). The 2 shift solenoid is about USD30 each.
I also asked him if we needed to change the (TCC) Transmission Control Circuit Solenoid and the Transmission Fluid Temp sensor, and he advised not to.
No mention of the Pressure Control Solenoid though, nor the Accumulator spacers.
What do you guys think?
Also, if we change the Shift solenoid, is it also easy to change the TCC once we remove the Shift Solenoid?
Thanks all.
