Question about 1999 Volvo S80
When i first started out this morning it stayed in first until 5000 rpm before shifting to 2nd. Then the car wouldn't accelerate past 40 Km/hr (no missing or sputtering just no response from the accelerator). I switched to manual shifting and it wouldn't go past 3rd gear. I had almost given up; I backed up a little ways and decided to try again and everything started to work fine.
Any idea what this is?
The cheap fix: Speed sensor connected to the Transmission Control Module (TCM). That screws up the engine control module and could throw you into limp home mode. Expensive fix: Transmission control module. Start with the speed sensor. Suggest that to your mechanic and get a second opinion before changing out the TCM. It's a simple plug and swap, but the module is expensive. I bought a spare on Ebay for my Volvo for $10. The TCU, I believe, lives under the right front kick panel, at least that's where it is on my 740.
