I've had a VLT BT1 auto for about 9 months now and it has nearly 300,000kms on the clock and getting a bit tired. The car has developed a really bad slipping problem in the last couple months. It seems worse when its cold too. Basically you put it in drive, put the foot down gently and it slips serverly, then shudders a bit then seems to "vibrate, grab and kick in" and lockup the driveline for normal driving. If you try to acceralate faster, the thing slips worse and then "bang" big time shudder through the car and then no more slip. With the faster takeoff's you can get axial tramp bigtime. It is amazing how the thing goes from about 5% drive to the wheels to 100% drive in a 1/10 of a second. It happens when the car is warm in normal driving too. People, wonder why the car is taking off really really slow from the lights but the motor is revving fairly high. I reckon I should put up L plates and pretend I'm learning to drive a manual I'm trying to "nurse" the car because I can't afford to get the trans done. But its a pain when the traffic is queuing up behind you and you only have 5% drive, unless you floor it and then "bang" and you cross you fingers that you haven't broken anything. I'm leaning towards the trans, stall convertor, but maybe it could be something else slipping ? I don't think the diff is LSD. How about the driveshaft joints ? What do the other VLT / Commodore experts reckon, and secondly how much to fix ? and thirdly, how longs it gunna last if I nurse it ( 2 months so far) Thanks everyone. Stapla. Some original photos have not been recovered yet.

Firstly check your trans fluid level (asap!) if thats o.k then you are going to have to rebuild the trans. Mine cost about $2200 with a 2800 Hi-stall. I got it done at Yarra Valley Automatics in Lillydale. Has been going great for 5 years with 450hp.

my cars just started doing it, i drained the auto fluid, topped it up with some quality ****, took it for a long drive, and it seems to be ok now.. im driving mine like citizen grandma at the moment coz i cannot afford a rebuild... for a while!

i have the same problem and it is my tranny also , my tranny is leaking fuid in a big way , it only happens when it is low on fluid i am going to change the filter and pan seal and top it up hopefully this will get rid of the problem also this is my 2nd tranny and last time i just bought a vl tranny out of the trading post for $250 and slaped it in BTW my ride is a Ser 1 R31 Skyline
