I have a 99 S70 N/A. The car starts and runs fine but when you put it in any gear, the engine stalls.
If you rev it and neutral drop it, it goes and the tranny seems to function fine. Am I looking at a torque converter
or is the whole tranny shot? Other ideas?
Thanks.

Please enlighten me. I just picked this car up for $600 and I knew it had issues. This is my first foray beyond a 98 model so tell me what's up. It is in excellent shape inside and out and I don't mind spending money on it.
It drives just like a car that you can't put the clutch in.

neutral dropping any car will result in destroying the tranny. its just a matter of how many times till its fucked. anyone else gonna back me up on my special mechanic skills.

Has it had the ETM serviced?
Any CELs?

if your converter is stuck in the lock postion you wouldnt be able to keep the revs up when you drop it in gear.

if these cars have an idle air control valve id start there and see if its gummed up

Does it stall when you come to a stop with it in gear after driving? If no, then the issue most likely lies outside of the tranmission. Before you go worrying too much about the ETM, make sure you don't have any massive vacuum leaks.

if the transmission is working fine, then I would think about the engine. Although if the torque converter is in full lock, then you would get a stall situation. it is rather rare that a torque converter will fail. Although to think of it, I'm replacing the torque converter in my car.

the other thing to consider is when a torque converter goes into full lock. It is caused by reversing the hydraulic fluid. I don't know how the transmission reverses the hydraulic fluid but if its solenoid controlled, then one of the solenoids could have gone bad. this is just a guess if nothing else pans out.

'99 don't have IAC valves. the ETM controls it. Clean the ETM and check the PCV system. If the throttle plate is getting stuck then the car can't compensate for the load. It happens a lot with the N/A '99- the idle just fluctuates and sometimes dies because the ETM can't adjust. Definitely sounds like engine concern and quick repair rather than trans.

If the converter was stuck in lock out the engine wouldn't turn due to converter and the trans still being engaged while the engine was starting. There are other ways for the converters to fail but that is the most common. Doesn't happen often to Volvo's.

can this be the etm problem arising?

[smokin' T5M]

could be but I wouldn't jump to absolute failure. Check out simple servicing first.

Well, if you started it in park or neutral, it would turn over, but immediately stall with a huge clunk when it's put in gear. Just like if you dropped the clutch on a manual

But yeah, clean out the ETM, and see how it does. The inside of the throttle body is most likely just gummed up

Damn the torpedoes...
I have the tranny out. The torque converter seems ok but the outside input shaft on the tranny
is tight as a drum.
I don't know diddly about auto boxes so I don't know if this is normal.
I am just going to put in the tranny from my 98 (now wrecked) and go from there. Besides,
I will now get a head start on putting in a new RMS.
On a side note, I did talk to the service manager at the local Volvo shop
and he verified the ETM warranty is 10 years/200,000 miles and the software recall is just that, a recall
so no time limit.

[smokin' T5M]

Precisely right! They have to do the recall S/W update before they can do any mechanical repairs or replace the unit. Catch 22: If it's not the ETM causing the interruption then you will have to pay for repairs needed to make the car run correctly. If the ETM fails(9 times out of 10) then it's covered.
