Car Forum / Volvo Cars / June 20081990 740 transmission problem
I have a problem with my auto gearbox and was wondering if anybody had a similiar problem and how it was resolved, the gears change ok but seems to rev high before changing, its as if kickdown is on all the time, when reversing I have to rev to about 4000rpm and even then it only goes back slowly, on the open road it accelerates ok but still revs high and is difficult to keep at a constant speed , thought it might be the clutch but if I kickdown it accelerates no problem even on a hill..thanks in advance..... > I have a problem with my auto gearbox and was wondering if anybody had a > similiar problem and how it was resolved, the gears change ok but seems to [quoted text clipped - 4 lines] > if I kickdown it accelerates no problem even on a hill..thanks in > advance..... The *best* case scenerio is you are dangerously low on transmission fluid. Don't drive it until you get it diagnosed. I've checked the fluid level all,ok....... >> I have a problem with my auto gearbox and was wondering if anybody had a >> similiar problem and how it was resolved, the gears change ok but seems [quoted text clipped - 7 lines] > The *best* case scenerio is you are dangerously low on transmission > fluid.

Given the effort to swap one in, I would be more inclined to rebuild the original one or have someone rebuild it, or get a used one and rebuild that. Unless you're doing the work yourself or find a known good low miles used one, it isn't really cost effective to pay someone to install an unknown junkyard tranny. >> That means that you will probably need to look for a used >> transmission, but have it checked first at a shop you trust.

The odds are pretty good with those, especially if you get one from a wreck with reasonable mileage. It's always been my understanding that rebuild jobs, unless done by an actual factory-trained refurb outfit (not a transmission shop), often don't go well. So I'm going to go with "get a used or certified rebuilt transmission." >>> That means that you will probably need to look for a used >>> transmission, but have it checked first at a shop you trust.

They do tend to be fairly dependable, so long as you don't crack the heat exchanger in the radiator and run water through the tranny. >>>> That means that you will probably need to look for a used >>>> transmission, but have it checked first at a shop you trust.

I've been away from these cars for a while, now. My only remaining Volvo is my first car, a '67 122S that sits moldering in my garage...anyway, a used transmission from a reputable salvage yard that can tell you it was shifting ok and the radiator wasn't shot, given a pan drop and clean, filter change and as much new fluid as possible, is probably a good bet. > I have a problem with my auto gearbox and was wondering if anybody had a > similiar problem and how it was resolved, the gears change ok but seems to [quoted text clipped - 4 lines] > if I kickdown it accelerates no problem even on a hill..thanks in > advance..... I had a similar effect in a 244 with AW-70, twice. The cable which transmits the accelerator signal from throttle to the gearbox was sticky. Accelerating would pull on that cable just OK but the spring which should move back to idle position couldn't make it. Open the bonnet, locate the throttle, note the cable going to your accelerator pedal and the other going down to the gearbox. Turn the wheel mounted to the throttle (same as accelerating), let it flip back and watch the connection to the gearbox: it should follow immediately. If it doesn't replace that cable (~200 EUR at the shop 10 years ago).

Unusually you can fix it by squirting some lubricant down inside the sheath. >>I have a problem with my auto gearbox and was wondering if anybody had a >>similiar problem and how it was resolved, the gears change ok but seems to [quoted text clipped - 18 lines] > Bye, > Vitus I'm sure we all thought of the kickdown cable immediately, but most of us dismissed it as the culprit because of the behavior in reverse. Did your car do that as well...? Has the oil level been checked properly and is it the right oil?Make sure the cable on the tranny is loose as can be then tighten to desired effect .It worked for me .I did the cable by the book and it was a problem ,doing it slowly up till it was right worked well .I was advised by a Volvo mechanic to do it this way . >> I have a problem with my auto gearbox and was wondering if anybody had a >> similiar problem and how it was resolved, the gears change ok but seems [quoted text clipped - 21 lines] > Bye, > Vitus
