Message: <blockquote data-quote="Iylia H" data-source="post: 612678" data-attributes="member: 18548">I had this on my e34 for a couple of times. The first time it happened was when I crossed a puddle of water, didn't expect it to be that deep. Had to drove all the way from shah alam to my home in subang jaya, with the trans fail. It was nightmare trying to get the car moving every time i encounter a traffic light. Arrived home, off the engine, and turn it on again, everything went normal.The next few encounters, are all due to me driving in slow traffic, and when the road clears up and i accelerate, the gbox refuses to switch from 3-4. Can feel the gbox slipping, as the needle goes 4k in normal driving condition for a while. Like any other auto gbox, what i do is, i accelerate and pull my leg off the accelerator to force the subsequent gear in (did it over and over as gear still didn't shift). However it then followed with a loud thud and a jerk, and the car went into transfail mode. So what I do after that is stop, off and start the engine, and things turn normal again.Since then, if the gbox decides not to shift, I don't force it to change by pressing and depressing the accelerator. I just let the gbox sort it out itself. After about 5 sec of constant 4k on the rpm, it will subsequently shift to the next gear. Suspecting the gbox cooling system is faulty, that's why it happens in traffic jams for me. Thank god, it has not happen for a long time now. Now I less rempit from standstill, preserving the gbox.</blockquote>
