Default Zen in the Art of Volvo Maintenance

This summer I rebuilt my family's dying volvo 245 glt. I installed an intercooler, dropped in a rebuilt engine, replaced the entire suspension system, wiring harness, interior, and even added cruise control. All this was in preparation for the most grand road trip ever: one month, one man, one bad ass Volvo, and the Great American Desert. My goal was to hit every national park between Denver and San Diego, I was slightly delayed. The first week and a half was great (Chaco Canyon National Park may just be the coolest place on the planet), but that last sign as I headed through Kingman, Arizona that read: No Services Next 30 Miles still sticks in my head. 12 miles later... BOOM. That was my transmission. Fortunately, sometimes I still had 1st and 2nd gear. After three days at the Kingman KOA (wow, don't ever go there!), I found a transmission located in Las Vegas, 100 miles North. 11 hours, one blown tire, and 2 1/2 gallons of ATF later, I had my new transmission, in the back of my car. Thanks to Memo, a selfless parts puller who offered to help me do the work for pennies of what I could not afford to spend, my Volvo was back in action. He had worked a full day in a Las Vagas junk yard and had another full day ahead, but stayed up with me installing the damn thing till 3 am, my belief in the human race has been restored!
So I made it to California where I visited some family, then headed back for round two of the road trip. This time I was heading North, through Utah and all it's glory. With one day left, I was nearing I-70 and the home stretch when... BOOM. That was the head (the coolant line going into the engine blew). And this time I was 20 miles from a town, with no cell reception. To make a long story short: three days later I pulled up to my house in Denver with my beautiful volvo, on the back of a U-haul. Over the coarse of the road trip I also lost power steering, blew another tire, even cried once, I think I'll write a book. Anyway, I fixed the head in record time and was only a week late for school in Montana.
Now the car is running great, but my problem today is: The transmission I dropped into my car was from a 1990 and I have an '83. The speedometer used to plug into the transmission, now I am informed that they are electric, pulling their data from the rear axle. How hard, if possible is this change to make?

The tone ring is instaled on a groove cut in the differential. The sensor is in the cover.
If you have access to a newer rear, put that in. If not, you need a later diff and cover, and someone to help you put it in.
For the other end, you need a speedo and the extra wiring.
My advice is to drive the car as is, and find another trans later. Other options include buying a complete parts car.
Another possibility is changing the tailhousing on the trans, but that is only if the output shaft is compatible.

Sweet trip man!! How many miles total did you put on it? You just can't have a good roadtrip in a volvo without something going wrong, it's all part of the fun of it. Time to post some pictures.

In September I too took a month long roadtrip in my rebuilt 244, and pretty much had as many problems as you did. But we both prevailed!!! I put 7,400 miles on it.

Time to post pictures man.

Sounds like you had one nice road trip with a few hick-ups. Be sure to remember that way-cool-and-friendly junk yard guy with something nice, after all chirstmas is just around the corner.

As was suggested the easiest way to convert to an electric speedo is to get a whole rear axle and the speedo cluster from a junk yard car.

Or if you like to spend big dollars to get an after-market speedo, you could also have a tone ring welded to your front wheel hub, and mount a sensor to the brake shield plate (preferably strenghtened).

Though getting the std. Volvo stuff will be a whole lot less involved.

My odometer is broken but I think about 3500, minus the last 500 which were courtesy of U-haul. Pictures soon, not many though, my camera broke on the trip too!

I don't even want to touch the rear axle, after market might be the way. It's going to be a fun weekend!

A low-budget approach would be to cut grooves, or weld spots, on the hub. But if he has limited cobbling skills, not a good idea.

Ok, how about this. Screw the speedometer, can't I just use the tachometer to find my speed and if so what are the ratios. The engine is a B21FT with an AW71 trans.

uh ya'll are crazy

would not it be easier for him to just get the speedo gear, spacer and tailshaft housing off another AW70/AW71 out of a 240 and swap those onto his 90' AW71



did i read the thread right and everyone else just space or what?

he has an 83' 240glt ... and installed a 90' trans ... which means just use the tailshaft and gear and spacer off a 240 w/ the cable driven speedo as they swap right onto his current trans

Just get a GPS unit. Most of the models (even the cheapy ones) have a current speed function.

Or borrow one and calibrate the tach (for level ground, constant speed since that tranny doesn't lock up?).

I haven't actually tried it, but it might even work to make the sensor sniff the wheel bolt heads on the backside. Though that's only 5 pulses per rotation.

I have used the tach many many times, it works. Use a cheat sheat for various gears/speeds in town.

And yes, the GPS recievers are accurate in showing speed. I have a Magellan explorist, and it is very accurate, except the baro altitude is not auto-correcting for weather. But it has a good compass that works when sitting still, so I forgave it.

I thought of that, and was wondering if it would work to cut grooves in the bolt flanges to multiply the number of pulses.
Or build a cheap freq. multiplying circuit.
