Hi

Does anyone know of an online transmission store where one can buy individual gaskets and parts for the valve body for AW71 transmission?

Thanks

Gus

Hi,
I just did an overhaul on the AW-71 transmission out of my 740 sedan. I ordered parts form FCPEURO.com, but they took a long time getting to me. I went to my local small auto parts store where a lot of the local shops buy their parts, and got the seals that I needed there, , because I was sent the incorrect shifter seals and the rear end seals. I did get a good quality oil pump seal and the engine rear seal from FCP. So you can try them, but be specific when you order. They a have a good customer service dept.
The trouble with buying on-line as I've found out is that sometimes you get something much different than what is ordered. Not always but often enough that I only order the hard to find items.
BTW, I discovered that the kick-down cable is not available any longer. The original out of the transmission I have now is still workable, but the rubber grommet is burnt, so I made up something that works.
The local PicknPull yard is a real savior when it comes to finding those parts I don't want to buy new or don't need to be new.
Good luck

Thanks for your response. I have been experiencing a problem only with my up shifting from 1st to 2nd gear. Car shifts normally when cool, but when it gets warm the only way to get it to shift is letting up on the throttle after 2500 rpms. A transmission repairman says that either something is wrong with the kick-down cable or the 1st – 2nd gear modulator valve is sticky.

So I am going to replace the kick down cable for starters and if that does not work then the 1st – 2nd gear modulator valve. Which means I need a place to buy a new valve or I will replace it with a used one.

How many places did you try to get a new kick-down cable? It appears to plentiful on the internet.

Dear gus123,

Hope you're well. Volvo VADIS - the now-superseded dealer parts/service database - shows various gasket, spring and seal kits for AW-71 transmissions.

For example, a gasket kit (#271393) costs about $40. A spring kit (#270159, for trannies with the locking torque converter) costs about $10. A sealing ring kit (#273494) costs about $30. These kits should be available from Volvo.

As to shift valves, there is a shift valve (#1239938), described as "shift valve long 2-1". It should cost about $40. There is a related part, "shift valve short 2-1", (#1239939), which should also cost about $40. A tranny expert should be able to tell you which of these is the needed repair part.

Even if neither of these parts is the one you seek, these parts' availability from Volvo suggests you're like to be able to get other internal transmission parts.

Because these Aisin-Warner trannies are quite durable - and until recently have been plentiful at salvage yards - I'd guess Volvo still has most internal tranny parts. As salvage yard trannies have been plentiful, re-building is not economic. Thus, the supply of internal tranny parts that Volvo acquired has not been much drawn-down.

Hope this helps.

Yours faithfully,

Hi- I tried several places, online shops and my local auto parts store. I took a drive to picknpull to see what I can find. Most of the cables are broken or cut. It's to late now tho, since the tranny is back in the car and I don't wan to mess with it. The original is working, I think. The gears won't shift out of high , like from 2nd to 3rd.
The engine revs high cruising along at 50 mph., about 2800 rpm. I tried adjusting the cable and I think I need to mess around with it some more.
I didn't touch any of the inside parts and the transmission was working fine previous. I wonder if it has anything to do with the soleniod? I took it out and by passed it, as in the FAQ on the AW71. Puzzling to say the least.

Dear volvosenior,

Hope you're well. The symptoms suggest the overdrive relay may have failed. At the bottom of the instrument cluster, there is a line of "warning" lights. Is one of these - an orange arrow pointing towards the top of the cluster - illuminated?

If so, that means the overdrive relay has failed. This relay (white, 2" tall, and 1" square) is located on the central relay panel (behind the front center console ashtray). The overdrive relay is in the middle row, on the extreme right (passenger's side, North American meodels).

When you turn the key to "on", all of the "warning" lights should come on. If you do not see an orange "up arrow", then the lamp could have failed. Replace the lamp. If, after start-up, the orange "up arrow" remains illuminated, replace the relay with a new or "known good" used unit.

That may resolve the shifting difficulties. If that does not, post back.

Hope this helps.

Yours faithfully,

I am sure you tried it already but just flushing the fluid has done wonders for the exact shifting issue you mentioned in my 1993 940 although it was from 1-2, 2-3 and even into OD. The shifting quality keeps getting better very day (now about 2K miles since the flush) so I do plan to do it again in late summer.

Kickdown cable in mine has plenty of slack so I am think the remaining resistance to shif is likely binding or gunky crap on the spool in the tranny.

Hi

As of yet I have not flushed the transmission fluid yet. The transmission specialist said the fluid looked good, but he did tell to drain it and look for particles in the fluid. When it warms up here I will examine the fluid and replace the kick-down cable. Then I will see if the transmission behaves better.

In the mean time I am searching for a place to buy transmission parts, the specialist also told me that there is a possibility that the 1st – 2nd gear valve maybe sticking or the spring that pushes it may be defective.

The car is very drivable by starting out 2 on the shifter and sliding the shifter forward when it is exceeding the 2nd gear limit or starting out in D and releasing the throttle momentarily when the tachometer reads about 2,500 RPM. Both methods allow for smooth shifting. In addition, this transmission was rebuilt four years ago.

Flushing takes 30 minutes, 3 gal of cheap Dex, a drain pan and a 3/8" x 4' piece of cheap tubing. The tools required are the open-end wrenches for the fluid line (12 and 13mm I think) and what ever tool you use to loosen the drain plug (large adjustable wrench in my case)...oh, a funnel capable of reaching the fill port.

Just saying, do it as part of the draining of the pan and replacing the cable. If the valve is sticky, it will almost guaranteed unstick unless the transmission has a former history of coolant contamination.

Dear Gus,

Hope you're well. You might want to contact Aisin USA. They might be able to direct you to a company, that sells the parts you seek. Most parts should still be avilable from Volvo.

Here's Aisin's contact info: Aisin World Corp. of America; 24330 Garnier Street; Torrance, California 90505, U.S.A.; Tel: 1-310-326-8681; Fax: 1-310-533-8271.

A transmission specialist might also be able to point you towards a supplier of Aisin parts for the AW70-71-72 trannies.

Hope this helps.

Yours faithfully,
