pint4 Posted June 26, 2010 Share Posted June 26, 2010 My 35 Buick Series 40 transmission grinds just about everytime I shift from 2nd to 3rd. I have to play around with the shifter to get it into gear. My son would love to drive the car but I don't dare because he would problably trash the transmission as soon as he shifted it from 2nd to 3rd. He is still new to manual transmisssions. I would like to find a replacement if there isn't a fix and am told 1934 through 1937 Buick Series transmissions will all work. He would like to drive the car to a show. Any thoughts/ideas?Thanks,BobIf you have a transmission for sale, my email address is pint4@new.rr.com or ph: 920-731-8519. Link to comment Share on other sites More sharing options...
Larry Schramm Posted June 27, 2010 Share Posted June 27, 2010 One thought is have you changed the lube in the transmission? You might try changing it and see if it works better. Link to comment Share on other sites More sharing options...
Owen_Dyneto Posted June 27, 2010 Share Posted June 27, 2010 (edited) Assuming the gear oil is of the proper viscosity and filled to the proper level, I'd suspect that the sychronizers are badly worn.

Mark Shaw Posted June 27, 2010 Share Posted June 27, 2010 Old Buick transmissions require a slow moving short shift cycle. Try going only ten feet in first, fifty in second and then shift into third... while going only 25 - 30 MPH with 3-5 second counts between gears.... Use SAE 250W gear oil too....My 2 cents...

Guest cben09 Posted June 27, 2010 Share Posted June 27, 2010 Is the clutch releasing completely??,,,Ben Link to comment Share on other sites More sharing options...
pint4 Posted June 27, 2010 Author Share Posted June 27, 2010 Thanks for the suggestions. I will check these out. If it is snchronizers, then maybe it would be better to replace the transmission. Are there adjustments? What do the flat sprinegs do?Thanks.Bob Link to comment Share on other sites More sharing options...
rgshafto Posted June 28, 2010 Share Posted June 28, 2010 Sounds like a worn 2nd gear synchronizer; had the same problem on my '36 Pontiac. A good old time transmission guy can fix it easy, once you get it out of the car (that's the time consuming part). Northwest Transmission Parts is a good source of such things. Ask for John, 937-442-2811. Link to comment Share on other sites More sharing options...
