BW35 Problem 1800 1972

The 1800ES I drive has the dreaded BW35 automatic transmission. It has worked well, within its limits, until yesterday. About a mile from work I took off from a stop light and it would not shift out of first gear. I drove slowly, keeping the revs below the redline, and made it to work. The fluid was low, so when I left work I added some Type F fluid. The problem didn't go away. I live less than 10 miles from work, and the driving is all in town, so I decided to try to make it home, going slow. After a couple of miles it would shift into second, but the shift was rough. This morning I added a bottle of Lucas transmission additive and took it around the block. It never went out of 1st. If I have the the shifter in 2nd or 3rd it will take off in 1st, but then seems to slip. I think it is actually engaging the other gear but they are slipping. I would like to keep this thing running for another two months, and plan to put in a 4 speed with overdrive this summer. Any hope of making that happen?

    BW35 Problem 1800 1972

    Its possible taking that a tranny shop might be able to adjust something to eek out a few more months of use. But that would probably just be a hefty bill - if I were you I'd just spring for the M41 swap now. You might try pulling the pan yourself and seeing if you can find the adjustments for the clutch bands yourself, and seeing if there is some sort of filter you could clean.

    I've never had good luck with auto tranny Volvo's. The two I've had (an 1800E and a 145E) both had the trannies go out within a few months of my ownership. I didn't abuse them, but I do tend to drive with a heavy foot. Both just started slurring shifts, slipping under full throttle in 1st gear. Both got manual tranny swaps, which made them both much better cars.

    On the other hand, my Mom's '71 145S wagon made it 250,000 miles on the original tranny, before she traded it in on a Jeep Cherokee. Although the Jeep now has 275,000 miles on it and is still going strong. So I think that has more to say about the gentle way my Mom drives cars.

    chakra;

    BW35 strikes again! I can't be of much help with BW35 experience...besides pulling the pan and changing filters and checking the obvious, it will probably have to come out of the car...getting and installing a used one might be the least expensive solution....gee, maybe this is just the opportunity and reason to convert to an M41/OD...sure, this is a bit of a project, but its pretty unlikely you would regret it in the end.

    Good Luck!
