Lock up torque converter 900 1993

I don't think acceleration too different from the 240. Good acceleration at first and second and no complaints with third and OD for a 113HP engine. I can take most of the I77 mountains through Virginia and WV in third unless an 18 wheel cuts me off.

The 5th gear. Lockout occurs at 48 MPH at a mild acceleration. You can see the tach drop a few hundred RPM and because it is so subtle you cannot feel it but if your one with the car, grasshopper, you can feel the RPM drop. It seems like lockout drops out at about 45 MPH, decelerating with slight pressure on the throttle.

There is an 8 mile 45MPH hilly stretch of an 18 mile trip to work and I try my best to keep the car in lockout by speeding a little down hill and easing it up hill.

Improved MPG, sure, how much is the question. Keep in mind that in lockout there is no wasted energy, pushing fluid, inside the torque converter.

Hardly an accurate measurement but, newish tires, full tank of gas, night time, a half a pack of smokes with my sunglasses on, started a 325 mile trip during the remnants of hurricane Francis, 1998. It was a bad drive. All I could do is try to keep the car in lockout at 48 MPH while the speed limits were 55 to 65 MPH. Results, 31 MPH. Kidding with the smokes.

The only thing missing is an ecoT light during lockout but eco wasn't in vogue at the time. I'm sure Volvo missed a great marketing tool with lockout.

By all means, check the transmission label to make sure you have a lockout tranny or better watch the tach drop at 48MPH.
