Thread: Auto Gearbox Strangeness...

Steve,
your problem sounds a little bit like what I had, albeit, mine is a tdi.

It would sit on about 2,500 revs at 100kmph, give it a kick to move on a bit or to overtake, I would only notice this with the tacho, the revs would jump 2 or 300, over what it was sitting on, but the car would not increase in speed, had me wondering, torgque converter, don't have cruise control.

Anyway now it sits on 2250 at the same speed, what fixed it, wouldn't have a clue, but after I had the timing belt replaced, in december, everything was fine, I did find out though the timing on mine was out by a tooth or maybe two not exactly sure. ( dealers did the previous, recall, change)
Since you mentioned you had it chipped maybe the chip isn't timing correctly, just a thought, i think the auto boxes are the same.
Perahps a more learned 'chip' experts will give their view.
But the similarity is uncanny.

Thanks John...

car runs fine... and does increase in speed when it has this problem.. to be honest it pulls like a train, im stunned at the difference.. so im not thinking engine problems.... im just thinking an occasionally lazy torque convertor lock.. or over torque protection... but the inconsistency is whats confusing me (easily done) seems strange tho... it worries me as i dont want it slipping hitting a big hill towing.. if it doesnt need to!

Thanks

Steve

Yes mate, mine now does the same, almost to the speed of the batmobile, in pickup, but there is no lag when i give it a bit of boot, a lot of boot makes it kick down, like it is supposed to,
thats what made me wonder what was wrong with it pre new timing belt.

john

been doing it again today.. watched it a bit more carefully.. but i still honestly dont know what causes it to start...

down the freeway on way back from work... 90kph... give it a toefull and instand pickup... no lag.. however after a very short period of time (maybe half a second) the torque convertor starts slipping but only by about 2-300 rpm above its locked speed. car increases speed in normal rapid way.. ease of the accelerator and it comes back down to 'normal' locked rpm none of the usual pull felt that i associate with the torque convertor locking at 80k's all nice and smooth....

its definitly not a lack of power as the car increases in speed and pulls like a train its not kickdown as the slippage is controlled.. so please is this normal? as far as landies can be 'normal'

Thanks again

Steve

how long since the oil was changed?

thats a very good question.. i have only had the dII since december.. and its due its 100k service very shortly.. but it does have full dealer service history (not that this means much)

could that be a symptom? this is my first time with an auto... and its only been noticed with the extra power..

thanks

Steve

.....I don't seem to have this problem in the Series IIA.


NOTE TO SELF: Ask Uncle Ho whether he has this problem in his Series

my habit was that anytime the auto did unfamiliar things i had it serviced.. they usually stopped when i did.
