I tot i posted this already but dunno where:
Problem: i had been receiving 'Transmission Failure' warning on several occasions and usually when going downhill. i don't have any transmission slams or jerking so I have always just restarted my car and the message will go away. I had then since been more aware of my driving style and made sure i did not stress the car too much. Out of 5 times, 4 times I will get the 'Transmission Failure' warning when going down a slight slope from my moms place. I had then since tried to 'press the brake' method and ensured that my leg was at either the acceleration or brakes when going downhill to avoid the message but never 100% effective.
Bigger problem: Last week I had the same darn thing appear again on my screen and this time restarting the car did not make the warning disappear. Thus, I had to go to my mechs. All ready to spend the 4-5k needed to change the necessary, I told the guys my dilemma and pointed out that I felt NO gear jerks or slamming as well. One of the foreman then suggested i change the IBS or negative battery thinghi (with the since i have never done so. Nearly fell of the stool when they told me the price but I figured why not!
Solution: After changing the Negative Cable, I did not really want to 'test' to check if it was really the culprit cause my heart would just sink if the 'Transmission Failsafe' thinghi came out again. Thus I drove my usual style not trying to invoke the wreath of my car. Ultimately tho, I had to go up and down the hill at my moms and I noticed that the gear change down gear had no more drama! Ekekeke....not wanting to celebrate yet, I tried it a few time releasing my feet completly off the brake and acceleration as i went down the hill and...all is well! I drove like a mad person just now as well (not intended, just the way my mood went) and again...smooth power of the car all the way! So I can 'pre-maturely' say....that the culprit was indeed the IBS Negative Cable for me (I really really hope).
