Volvo 850 Transmission Solenoid Replacement DIY

Volvo 850 Transmission Solenoid
MVS Forums contributor and fearless Volvo DIY’er polskamafia mjl tackles the  Volvo 850 Transmission Solenoid Replacement DIY:

This is a write up for replacing the shift solenoids in the AW50-42 transmission on a Volvo 850. My particular car is a 1995 model and the S1 and S2 solenoids are different. Earlier models had S1 and S2 as the same solenoid. This explains why many Volvo parts vendors have the same part number for S1 and S2. On 95 and later model cars with Aw50-42 auto transmissions, S1 should be 5040310002N, S2 is 6843783 and the lock up solenoid is 6843784. Most vendors have the solenoids for $100+ online; I got mine from Trans Parts Direct. Theirs are $23- $25 so much, much cheaper: Trans Parts Direct AW50-42 solenoids.
