    66 riviera wiper

    I'm not sure what a " complete windshield wiper motor system " is, but the wiper motor is GM part number 4916037. It only fits 1965-66 Buick, Olds, and Cadillac full size, Riv, and Toronado. The 69 motor will NOT fit. Search that GM part number and you'll find potential vendors on the web. There's at least one NOS motor available on the web. Be sitting down when you see the price.

    Hahaha, thanks for the heads up!

    Ana, you may get some answers here, but I suggest

    posting your question also in the topic "Buick Riviera--

    Riviera Owners' Association."  Just scroll down the

    list of topics, and you'll see that category among other

    Buick-related categories.

     

    Plenty of Riviera specialists will see your question there.

    They are likely to have the part you need.  

    All the best to you!

     Thank you!

    Best regards!

    I believe one from and 2nd generation Riviera ('66 - '70) would work.  I'll bet that many GM wiper motors form '67 -70 would also work, but you may need to swap the bell crank and/or mounting bracket.  Those motors are almost bullet proof; chances are yours can be fixed.  Usually it's a matter of cleaning the contacts inside the park position mechanism.

    You can use the more modern, the ones you have, since the pushrods are solid you don't have to worry about losing oil/pressure the pushrods will seal the holes.

    Hi,

    I'm having a problem with one hydraulic lifter. After an oil and filter change, and cleaning the lifter, it's still making noise. In my 69 430 engine, I have solid pushrods, and the hydraulic lifters seem to be the ones that fit the hollow pushrods. Do I need to buy lifters that fit the solid pushrods only, or can I still use the ones I have?

    I'm new at this so I have no idea.

    Thanks

    It seems that the valve body gasket was the issue, I put another torque converter from th350 in, looks the same and fits right. now it goes to first and second, but I can't get it to go into third.

    It sounds like the torque convertor. I'd confirm that the fluid level is ok. Going uphill effectively changes the fluid level because it some of it flows to the rear of the pan. Also, the transmission is now under heavy load, trying to push +4000lbs up a hill. 

     

    If the torque convertor was drained, it has to be refilled, and it takes a lot of fluid. TH400's take about 6 quarts just in the convertor.

    Thanks for your reply.

    The symptoms were just like before, at first it was somewhat going to first, but then gave up completely. We took the transmission off the car again. The fluid has gotten dark already and some plates were burnt. (just tested the car in front of my house) I have another torque converter, so I'll give it a try with that one, I'll put some new plates and fluid in and see what happens.

    Yep, it'll still work. What happens is that the pump can still pump a volume of oil, but at a lower pressure. It's losing pressure because an internal seal most likely failed, and the pressurized oil is spraying out of those seal areas, instead of being directed out the pump and reaching the control valves. The way the pumps are designed, they never really fail completely, they'll keep pumping. It's the seals that give out. That's why it would engage when you floored it.... it was generating enough pressure at high RPM to switch the valves and engage bands.

     

    For what it's worth, they're not that difficult to rebuild. My brother rebuilt his 64 Rambler's transmission (a Ford FMX of all things) in our driveway. You just have to be absolutely religious about keeping the internals clean, and making absolutely positive that you follow instructions. He laid his clutch packs out on a piece of plywood, and made sure to keep everything in order. I believe he did it in a half day, and that was taking his time.

    So, the guy installed all new traction plates, steel plates, direct clutch and clutch hub, because those were wasted as well. The transmission is back on the car. (the vacuum modulator was changed prior to the transmission rebuild) The filter and liquid is all new. Now, when I put it in drive, it starts going forward right away, when I put it in reverse, it goes reverse right away. But when I try going uphill, it seems as the gears slip, and the car starts going backwards. Is that a torque converter issue or what? My troubles are not ending yet.

    Your symptoms now are different than your first post? Probably a good time to take the car to someone who is able to evaluate the symptoms like a trans shop. For what it`s worth, sounds like the pump,

      Tom

    Yeah, it seems it's getting worse.

    I'll order a new pump.

    Finding a good mechanic that knows around american classics over here is no easy job.

    Thank you for the reply

    Check the line that goes down to the modulator  to see if it is plugged up as well  .

    I have changed the vacuum modulator, and everything is plugged in. The liquid level is ok. Reverse works fine. When I put it in drive, it acts as if it's between gears, I have to step on the gas multiple times to get it going. I don't know what else to do.

    Hi,

    my transmission in my 1969 Riviera goes reverse and in first gear. 

    It sometimes shifts to second if I step on the gas hard, and is often shifting  back to first when not necessary. There is no third. It's not missing fluid. Could anyone please make some suggestions of what it might be?

    Thank you.

    I sent him a message over a month ago. No response.

     

     

    $2500? Come on

    I called the guy, asked about the car, he seemed pretty nice. Then I asked him if it was okay if he sent me some pictures because I'm not able to come and take a look at it, he said he would, later he sent me a message saying that it got dark after he got home, so he'll send some pics tomorrow. That was a month ago today, still no photos. The guy really does not want to hear about no photos.
