My old thread disappeared. Thanks to those who replied. I had the injector seal replaced on my 1981 240 DL, after it was replaced the car is driving with less power. More importantly, when we start to drive, and the engine is cold the car shifts through all of the gears, once the car warms up, it does not shift into third and just goes nowhere. The fastest we can go is about 35 MPH. Had another mechanic check the kickdown cable, vacuum, and IAC hoses and he says that they are OK.

Any other ideas? Could the injector seal be defective or misplaced? Would that account for these symptoms? Did my transmission just "happen" to go the day after the car was serviced? Do trannys die with these symptoms?

THANK YOU!

/// There are no vac hoses to the transmission. What about the fluid level, fluid color? Have the transmission serviced. You should have the pan dropped and inspect the pick up screen. Failure to shift into higher gears is one of the signs of transmission failure. If the pan is filled with clutch material that would indicate the transmission is gone.

It is possible that material in the pan slowly blocks the screen as the hydraulic pump circulates the ATF. If you remove the debris you might get a few more miles from the transmission even though it turns out to be worn out. The clue here is that it does shift cold, before the screen is blocked. Cross your fingers.

It is possible to knock off a hose or wire when replacing seals etc. This would result in poor engine performance not transmission. Did you replace both seals on the injectors. Did you use either a Volvo kit or high temp o-rings? Look for other vac leaks, dipstick, oil cap, intake gasket, Bottom of the 1 inch flame trap hose. (Crack on the underside, bottom) Did you clean the orifice in the intake manifold barb, from the flame trap?

Thank you. You are the first person to explain why it shifts cold, but not hot. We had the injector seal done at a shop. We asked them what they thought of the tranny before they did the work, and they said it was fine. Literally the next day, it started acting up. I know that these things can be coincidences, but it just struck us as weird.

Thanks again, I welcome any other advice,
