    Problems, Driver Warnings or DTCs - Chevy Volt
    My 2012 Volt broke down and the dealership is quoting me $7500 for repairs. They would replace the motor 1? in the transmission and the AC compressor. To make a long story short my Volt coasted to a stop and would never turn back on, this was after a self-repair on the bearing that makes the...

    Problems, Driver Warnings or DTCs - Chevy Volt
    "Engine Unavailable" error & no help from Chevy to cover Transmission repair What up fellow Volt owners: I'm frustrated, sad, and looking for any last glimmer or hope or even just a place to vent. I purchased my 2012 volt from a dealer here in CA just three years ago at about 70,000 miles...
  4. Transmission Fluid Change: Better to be a little low or high?

    Care, Maintenance & Service - Chevy Volt
    Just changed my transmission fluid a little early at about 94k miles. Everything went smoothly except for it seems like more than the recommended ~6 qts came out so I assume that means they slightly overfilled at the factory. My concern is after I finished the fluid change, driving home I...

  6. 2017 Volt Premier Transmission Buzz Vibration

    Problems, Driver Warnings or DTCs - Gen2 Volt
    Does anyone else notice a buzzy vibration when the ICE is used while accelerating slowly? I can hear it and also feel it, most noticeable through the steering wheel. It is especially noticeable between 35 and 50 MPH. When acceleration stops and I hold speed constant the buzz will continue for...

    Problems, Driver Warnings or DTCs - Gen2 Volt
    I would like to share an issue I experienced on Friday May 5th. While traveling to work, my 2017 Volt LT turned on the engine check light and requested me to shift to Park.

  9. Volt Gen 1 Transmission 4ET50 explained with real parts.

    Generation 1 Volt (2011-2015)
    https://www.youtube.com/watch?v=dqM3YXEf1js Good video showing the internal parts. The Gen 1 is really a very clever design. Couple of things I really like: Use of 2 electric motors Use of "Clutch packs" for engaging or stopping rotating parts vs one way clutches on Fords. Plus geared final...

  11. 2016 Volt - Engine/Transmission Issues or Is This Regular Performance??

    Care, Maintenance & Service - Gen2 Volt
    Hi! Just purchased a used 2016 Volt and it's great. But I've noticed when it's in Hold Mode or even more so when the battery is completely depleted and I'm forced to use gas, I've noticed the loss of power a bit as if it's in too high of a gear sometimes. It's the equivalent feeling of if you...
  12. Transmission Chain

    Generation 2 Volt (2016-2020)
    On the Gen2 output to wheels is linked to the differential by a chain. On the late 70's we had a Jeep that used a chain to couple the output from the transmission to the center diferencial (at the time called Quadra Track). In our particular case, we had to replace the chain twice in 10 years...
  13. Is this my transmission drain plug not fully seated?

    Generation 1 Volt (2011-2015)
    So I just changed the engine oil in my 2013 Volt and noticed that this threaded plug looking thing was not fully seated and looking very peculiar. I don't think this is right. Can someone verify this is the transmission drain plug and that it's supposed to be seated or is this a feature I...
  14. Car Wash Actually Charges the Volt

    Propulsion Systems - Chevy Volt
    Very interesting -- took the car to get washed today and the place was one of those old fashioned car washes where the car gets pulled along a track. -- I noticed that while the car was moving in neutral (at 1 mph...) the display said it was in regen charging. Is this why the owners manual...
  15. 2 or 3 speeds transmission

    Suggestions for GM - Chevy Volt
    I have done lots of highway this weekend (and the past two other) On flat ground the kW consumption is quite OK when cruising at 100km/hr. However if I read the meter right, in extend mode I consume less electricity then when I run on battery for the same speed. I also feel I lost lots of...
  16. Can't Get Out of Low Gear When in Gas Mode

    Chevy Volt Engineering and Design
    Am loving my new Volt as long as it is in Electric Mode. It's zippy, quiet and I haven't had to go to the gas station in a month. However, when it transfers over to gas usage, it starts acting strangely. Upon acceleration from a stop, it sounds as if it is stuck in "first gear". It has a...
  17. 79,500 Mile Transmission Fluid Analysis

    Care, Maintenance & Service - Chevy Volt
    Finally got my report in from Blackstone Labs. "This is the first fluid sample we've seen from the Volt's 4ET50 transaxle system, so don't put too much stock in comparing this with universal average levels yet. We started with average numbers from a similar type of transmission, but we'll...
  18. Hillside Parking, Volt Rolled backwards

    Problems, Driver Warnings or DTCs - Chevy Volt
    :confused::(:mad: I have had my 2013 Volt for 6 months, have about 12,000 miles on it. I have parked it in my driveway everyday since outside in the elements and charge it there. I just got back from a trip in Michigan, ( I live near Columbus, Ohio, 368miles round trip) which emptied the charge...
  19. D vs L. What changes?

    Chevy Volt Engineering and Design
    This might be addressed elsewhere, but I can't find it. When you shift from "D" to "L" (or vice versa) what exactly is the change? I assume it's a mechanical change of some kind (as opposed to an electrical change) since there is a noticable change in drag when shifting to "L" while coasting.
  20. Transmission seal leak.

    Problems, Driver Warnings or DTCs - Chevy Volt
    With 1,700 miles on the odometer I took my new 2013 Volt in for service for the first time. I was originally focused on a pull to the right which seemed like an alignment issue. I asked them to look for a leak as well. I had spotted a small silver dollar-sized puddle of clearish viscous liquid...
