Hi, i'm new to this forum and i would like to congratulate and thank's everybody who is responsible for it. It is a highly valuable tool for us volvo owners.
Here it is, i have an apparently strange problem with mine, i searched this forum and found nothing quite near.
First i must say that last year i had a problem with my neutral switch (PNP), that i fixed, and i did'nt have the code erased since then.
I would call this problem a loss of power or a tranny slip. Sorry if i give many details but i think it's the best way to get the best advices.
Take note that it does this problem in manual or auto but since the last 200 miles i drove it in manual mode only to identify as precisely as possible.
1st example: when on a higway (plane surface) in 5th at 55mph, if i press the accelerator to get to 65 rapidly, most of the time it accelerates hardly. When i reach 65, i drop the accelerator slowly and sometimes it makes a bang! and it looks like coming from the tranny.
2nd example: if i climb a hill in 5th at 55mph and i floor it, most of the time, it does'nt accelerate or it accelerate hardly, if i downshift it 4th, it begins accelerate then no more acceleration, then it comes back or i have to downshift in 3rd.
Usually i can go up these hills in 5th.
3rd example: if i floor it from a stop, it is so powerful and fast in 1st we feel no problem, we begin to feel a problem in 2nd and in 3rd gear it still accelerate stongly then it stops accelerating like if i lost 30 hp then the power comes back then it goes and it comes back and it's more apparent in 4th and 5th. If in auto mode with cruise control, climbing same hill, sometimes it looses more than 10mph before it finally downshifts in 3rd to be back at set speeds. And on an easy hill with the cruise control on, sometimes after getting back the set speed, when it stops accelerating, it makes the bang! apparently in the tranny.
I know the 3 examples are related but i wanted to explain it well.
I flushed the tranny and used Mobil 3309 and no change. The serial number of my tranny is not included among the ones with the B4 cover issue, should i check it anyway?
Is it realy a tranny problem or is it with the turbo? My car is not even 90k and i own it since 75k, the previous owner told me he just changed the oil
in the tranny but when i changed it when the problem began, it was black.
Beside that, the car goes well, in city driving you feel nothing wrong, engine idles well and when the problem occurs no rpm drop.
I tought of changing the fuel filter but what about the bang i hear? Same thing if i go to the dealer (100 miles away) if the problem is coming from the tranny, will the upgrade get rid of that bang.
Any advice or opinion on this problem ????? :(
