Here is the description of the problem (2000 V70 XC with 130kmi):

Flashing arrow and CEL came on the other day. I think the car is currently in limp mode and stuck in 3rd gear. I drove home for about 20 miles at 55+ mph without any problem. While stopping that the light, the car kept lurching forward even though brake was applied.

Here are the problems:
1. At stop light, keep lurching forward even though brake was applied. Engine will stall (not stall in N or P).

2. OBDII scan reported codes P0740 (TCC circuit malfunction), P1618 (Manufacturer Contrl, Aux. Inputs, Aux. Outputs), and P0422 (Main catalyst below threshold)

3. The next day, restarted engine, clunk noise when shifted to R, and stalled when put in any gears (R, D, 3, 2, 1)

4. Can be driven sometimes and gear changing could only be done manually (i.e. manually shifted to 1, 2, 3, or D gear) but will shake and lurch upon applying brake to slow down to a stop.

5. Some AT fluid leaked at tranny/engine mating surface with AT fluid smelled like burnt fluid

Troubleshooting Performed:
1. Cycled PNP switch 15-20 times with shifter while engine was on and brake applied

2. Checked solenoid resistance with digital multimeter at gearbox connector at leads 21 (S1 solenoid), 22 (S2 solenoid) and 23 (SL solenoid). All came back about 15 ohms (specs 10-15 ohms). Is this a correct method for checking resistance?

Per this link (http://www.volvo-forums.com/t9850-transmission-aw50-42.htm), code P0740 is for a lock-up solenoid SL. Any ideas to troubleshoot further?

I am thinking about removing the valve body cover to physically check the solenoids. Is this really necessary? There is a slight chance changing AT fluid will fix the problem. Any other ideas out there before replacing the transmission? I will post this in other Volvo forum.

What lead you to believe that something was wrong with the speed sensor? Did you performed to see if the speed sensor was bad?

I stopped into the Volvo service department and started talking to a few of the mechanics...explained what was happening and they all said Speed Sensor or module. Start with SS. It took me ten minutes to replace it, reset the code and trans was shifting great again

Wasnt aware of rear sensor, replaced the sensor on the transmission (located under airbox)
Also ended up replacing transmission module and flushing transmission fluid as it appeared burnt. Seems ok now, shifting clean
