    Is this a thrust button and can it be removed?

    I have to agree that the single row Green bearings are no fit for purpose. Modern bearings are dual row and much stronger. But fitting roller bearings in the limited space available in a old Mopar housing is problematic. My green bearings failed 300 miles from home (Bishop, CA when I lived...

    Transmission question

    I have rebuilt a number of 727's over the years. Follow the FSM carefully and it will turn out well. Be aware that cleanliness is a necessity but achievable in a garage. I have found trans shops and machine shops that will replace bushings if needed for $50, so that is not an issue. For a...

    Flywheel Resurfacing

    As they take only a few thousandths off the flywheel in an even cut, and it is symetrical, all should be well.

    At what R P M does a 727a shift out of 1st into 2nd then 2nd to 3rd

    The Factory Service Manual has a good procedure for adjusting the throttle linkage. Paraphrasing, pull the transmission throttle position lever full forward. Put a 3/16" drift in the holes in the upper bell crank lever and through the throttle cable bracket to hold it in position. Make sure...

    automatic trany quest.

    From what I remember, the A727 and early 904 have 2.45, 1.45, and 1:1 ratios. The low ratio gear set for the later trans is 2.74:1. This applies to some 904's and 999's, but I don't know how to tell from the outside what ratio is used. There should be an application chart that has this info. Bob

    TCI Transmission is bad

    I have to admit that the A727 is intimidating to think about, but actually quite easy to work on once you get into it. I purchased a ProTrans unit for my 340, but didn't get it into the car for 10 years. Seals failed quickly, but it was easy to remove and replace all the seals. Broke a rear...

    741 v 742 v 489 housings

    I ran a stock 340 with a 741 case 3.55 ratio rear for decades. when new, the car ran 13.5 @ 105 with sticky H70x14's. I had over 350 runs on that combo and still have the same rear end 43 years later. So, I guess it is strong enough for a 340. Bob
