Hello<p>Theres a trouble with my geartronic 2006 s40 T5 with BSR PPC. When accelerating with some weight onboard (like me + 3) people or when accelerating heavily uphill the geartronic seems to have troubles locking up the gear <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0"> <p>Happens mostly in D mode but when in geartronic and locked 3rd gear with me + 3 guys and uphill flooring it happens too. Rev limiter bounces between like 3000 and 3400 and you can really feel the car pulling like you would be pushing the pedal to the floor for like half a sec, then releasing it and pushing down again then flooring again and so on. <p>Maybe the trans cant handle the increased power? I have 25k miles on my car and this is troubling me because i dont want to broke it.<p>I can try to explain better if you dont understand how it happens.<br>I know this is kinda of repost but the problem is getting worse and maybe someone knows whats wrong instead of leaving the car to dealer for a week and paying $$$<br>

Re: Problems with geartronic (gg)

That is a heavy load. Four big guys. Sounds like it is slipping. Time to change out the transmission fluid. I'm at 27k and plan on changing it at 30k. I haven't notice the yoyo effect you seem to be describing. I do notice the RPM goes high for a bit and drop about 500 after each gear change.<p>I don't usually have a lot of load in my car, but when I do 1/4 mile tests, I do notice it slips even at high rpm. I would brake torque at 1500rpm. Then when I floor it, the tires chirp all the way up to 6000rpm. At around 6300 RPM, the tires stop chirping and I see the RPM falls back to 6000 and increase again up to 6500. I think at 6000 RPM is when the torque really goes South which enables the torque converter to fully engage. I don't do this often. Just after every performance change, so I can see if there is a difference.

Cheers mate ill try that. Damn trans fluid is expensive <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/eek.gif" BORDER="0">

Re: Problems with geartronic (gg)

i used toyota type T-IV when i changed out my tranmission fluid.. it was $24 for 4 litres compared to the $160 that volvo was going to charge for the same amount.<p>so far, its been running very well and smoothly. a lot o fmy friends with S60s and S40s have also been using the toyota fluid.<p>some of my friends did quite a bit of research on this. apparently its because its JWS 3309 spec. even the lexus's use it, cos they also have aisin-warner boxes.<p>we partly suspect that in fact the volvo fluid might just be repackaged..<p>

Re: Problems with geartronic (Mistral)

I've noticed "weird" engagement in 3rd gear as well, been meaning to ask about it on here. When accelerating from a stop, I notice that shifting from 2nd into 3rd gear seems to have two fairly distinct stages. For example, the tranny may shift out of 2nd and into 3rd at 4500rpm. First the tach will drop down to say 3800rpm, then it'll "settle" down into 3rd at 3400rpm and accelerate steadily. Its like there's a 2nd 1/2 gear. <p>What's the deal? Related to comments by posts above?<p>Oh, and i basically hate our (any?) auto transmission. Coupled with the huge throttle delay, 1st gear takes way too long to engage from a stop... followed by a huge surge... then less power until it shifts out of 1st. When accelerating normally, I feel a huge peak in power during 1st gear, made worse because the peak doesn't last all the way until the shift into 2nd gear unless I add more throttle. If it was a bike I'd be riding a wheelie, then slamming the front down before shifting into 2nd. Normal??

Frankly, I think I'd pay the $750 (or whatever) to smooth that out. Or perhaps just trade for a manual transmission... meh, I dunno. I definitely miss the manual tranny on my last car - seems like a turbo car would be much more enjoyable with a manual transmission. <p>Sorry to hijak, but I'd be curious if others with chips have noticed smoother power in 1st. Also curious about any decrease in throttle lag?

When shifting, and when initially spooling up in the next gear, the torque converter is unlocked to smooth out the transition, and provide the engine rpm to develop torque and spool the turbo. Once the power curve starts to flatten a little, the torque converter is locked to deliver it. The 5GT performs the lockup function in all five gears.<p>Tom.

Re: Problems with geartronic (tmtalpey)

I went to the dealer today and got my 40.000km maintenance in a few weeks but they sayd that my tranny problem is probably not caused by trans oil. Thought they said they are going to try to fix it <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> Hope they will find the problem.<p>They also sayd that normally the tranny oil should be changed at 80.000 km but i think if the car is chipped and not driven so smoothly always then maybe its time to change the oil at 40

tmtalpey, is correct. it is the torque converter. i have a 2.4i GT and it does the same thing. for 1st and 2nd gear shifts you cant really do anything about the torque converter but i've found that if you rev to atleast 2400rpm in 3rd gear and then shift into 4th that the torque converter will lock automatically cause there is enough torque after the shift. though i'm still not sure why that even if you rev all the way to the redline in 2nd and shift to 3rd there is still a delay. <p>its terrible because when you are redlining it you dont get a smooth torque filled movement from 2nd to end of 3rd.

Re: (Syaoran68)

Anyone has upshift problem with their Geartronic? Mine is so reluctant to upshift that it takes two or more tries in order to move up a gear, even with 3000+ RPM.

The 2.4i and the T5 have different shift programs. The T5 is designed to slip to allow boost to build quicker. Ultimately though its a nicer program as it doesnt take to down shifting as much. I had my 2.4i changed to the T5 program, as I found the car too rev happy before.

Re: (Revolve40)

I am talking about when the car is in D. If your having problems talk to the dealer about it, if anything they will reset the adapters so the trans has to relearn based on your driving.<p><TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD><i>Quote, originally posted by <b>Revolve40</b> »</i></TD></TR><TR><TD CLASS="quote"><p>How'd you do that?</TD></TR></TABLE><p>Well they gave me a T5 loaner when I got my oil changed, when I came back, I told them that I didnt like how my car was too willing to shift and that I had troubles on the 2-1 down shift (that it was too willing to do). Then I told them that the T5 they gave me shifted perfectly, so they just flashed the ECU to the new program.<p>My torque converter is locked up whenever im in the manumatic mode. Its very nice. Other then that If Im light with the pedal in drive, it will spend most of its time over 2000 rpm locked up.<p>Alot changed with the T5 program for starters the traction control was much more forgiving, and the car now has more of a tendency to stay in a gear unless Im really on the gas. It just feels more like a luxury car.<p>

Re: (zerocover)

I did complain about the jerky transmission and the dealer did a software update and now the automatic mode is just perfect. It now even downshift automatically for engine brake (new software).<p>But in manual mode, however, I am very concerned. I rev the engine in 1st gear to 5000+ rpm but the transmission still refuses to shift to 2nd. And when I downshift to 3rd to pass and want to upshfit to 4th after passing, it wouldn't upshift until several tries. Sometimes I just push the lever in the "+" side but the gear still doesn't change. <p>Is this part of the torque converter programming? But I've driven 2 loaner cars with T5 engine and their transmissions in manual mode are fine.<p>Please help! Thanks!
