Another in a series of problems my son has encountered in sub-zero temperatures since moving to MN . . .

This AM on the way to work he called to tell me that the car conked out on the I-94/394 part of daily his commute from StP to Minneapolis. He said the car "lost power" and he was able to coast off the exit. Engine continued to run, but doesn't take up drive regardless of gear selected (any of 5 fwd or reverse).

So I'm sitting here 1200 miles away (in VA) trying to figure out the problem. I guess it could be anything from a catastrophic failure of the transmission, to clutch diaphragm, to one of the u-joints, or the rear-end. Given the cold WX, I guess it could also be the rubber hockey-puck-like thing between the transmission output flange and the driveshaft. Any others?

Given the current temperatures (a balmy 4*F), he won't be the one working on the car--likely going to Foreign Service in Roseville--but I'm still trying to get some idea of what happened so I can manage Mom's (and my own) expectations. Depending on the diagnosis, I also may be looking for a source of used parts!

Thanks in advance!

Turns out that the rear seal failed and the trans lost most of its fluid. Tech drained about a quarter cup from it. That does not bode well for the bits and pieces in the unit. He was able to see into the trans with a minimum of disassembly. The input shaft lost all of its teeth, and damaged the countershaft in the process.

I spent most of the PM searching for a used replacement part. Talked to Erie VOVO--they were very helpful, but didn't have one (also said they are moving towards an inventory of 1995 and newer--no more 2-/7-/9-series cars. FWIW, Voluparts in Atlanta no longer ships out of state (they didn't have a M47 anyways).

Found a couple, but at no-name yards. At least one offers a 6-month warranty (it's still in the car and and car is drivable-FWIW)

More to follow on this, but thanks for your support!

forgive the reference to one of my favorite jokes--trying to keep my sense of humor.

I thought about picking this up as an extra, but it sounds like you are in greater need!

M47 is $150. Will have to ask him for a shipping quote - could be around $100. But that's not bad for a trans, for sure..

Thanks again for the point out to this--unfortunately I can't get to turbobricks' classifieds. Could you do me a solid and copy /paste the ad and post it in this thread? Or send to me at sja_tda at hotmail dot com?

Thanks in advance!

Thanks--I'll call him!

Here's what I read on turbobricks:

Input shaft to layshaft gear shredded. 4th is not really a gear - it just locks the input shaft to the output shaft. Clutch shaft is locked to output shaft in 4th, power goes straight thru the top shaft and out the back. Classic "I lost everything but 4th" is either the toofies [teeth?] on input shaft or the toofies [teeth?] on the cluster gear are gone . . .

As I mentioned in my earlier post, I may need a used M47 soonest.

Thanks again,

Now that you've provided that extra info about fourth, then yes the main drive gear on the input shaft and the countershaft have parted company. You need a new/used trans, and the one you have isn't worth dismantling.

Thanks--I was afraid that might be the case. The shop (Foreign Service) is having a problem sourcing a used box in their area (Mpls/StPaul MN)--they've even called Strandbergs over in Centuria WI, but no luck.

Not sure what my other options are, so wish me luck!

Try Erie VoVo in Erie, Pa. They are a reputable (but not cheap) boneyard that specializes in used Volvo parts. They also ship nationwide. If you do a search you will find other sources that will ship nationwide. Maybe ebay?

Maybe there is a small grinding sound with the engine running, in gear, clutch pedal up. That would indicate that the hub of the friction disc is torn out, and not connecting the clamped disc to the input shaft. So you may need a new clutch.

Thanks for the response. Apparently it's not the clutch . . . though it will likely get one "while we're in there."

I just talked to Stu at Foreign Service--he said that the car has only 4th gear. Not sure what the mode of failure was. Because he's been unable to find a good used M47 up there (MN-Twin Cities), he'll start by taking apart the current box and see if it's repairable.

So, if anybody is familiar with that type of M47 failure and give me hint at what I'm looking at and/or knows where I can find a good used M47 in the local area, I would really appreciate it!

Thanks in advance!
