    How not to kill your Torqueflite transmission!

    I never knew that.....I have to wonder if my dad did anything like that with his '61, '64, or '67 C body Wagons....

    manual 3 speed ? A-230

    Maybe this will help; reference is here. Google makes me look so smart LOL: | Repair Guides | Manual Transmission | New Process A-230 3-speed Overhaul | AutoZone.com If removed, place two interlock levers in pivot pin with spring hangers offset toward each other, so that spring installs in a...

    Axle shaft broke 8 3/4

    As said, that spare shaft's splines have seen some hard use; they are 'mooshed' a bit where they engaged the side gears in the diff. For sure, I would wire wheel the crap out of it, and use a fine triangular file to clean out the rust, taking off as little. The taper difference won't have any...

    I think I found my vibration problem

    Good deal, TD, and thanks for letting us know. Checking angles on the u-joints has been on my list to do on my son's 'Cuda.... It may move up on the priority list now.

    Axle shaft broke 8 3/4

    And realize that the large + offset of those wheels puts a lot more bending torque on the shafts, and it concentrates the peak stress right at the wheel bearing.... which is where it broke.

    Bad Trans Cooler Mounting

    ^^^ It doesn't smell burned at all, or have any discoloration; only a few k miles on the whole car since I believe this was put in. But that's not a bad suggestion. 'twould be a good time to move the temp sensor too. Header wraps may be in the offing too, to manage the underhood and undercar...

    Bad Trans Cooler Mounting

    First to the loop in the rad, and then to the fluid cooler.....er, fluid heater LOL Now it goes first to the rad loop and then into the cooler in front.

    Bad Trans Cooler Mounting

    No, you don't want to do this..... mount a tubular finned trans fluid cooler tucked up under the car on the frame connectors, out of the airstream and a few inches from the exhaust. My son's car came this way and the trans temps registered 220-230 F on the interstate at 70 MPH in OD.....not good...

    71 Dart 727 w/suregrip having weird issue

    My son and I are gradually getting rid of vibrations and rattles on his '65 Cuda. The exhaust was hung from small rubber blocks wrapped in steel and bolted to the chassis. No much shock or vibration absorption there. We replaced the rear hangers and it is better, and will replace the ones in the...

    904 Downshift Squall or Howl

    Well, it looks like we finally figured this out....indirectly. The PO had arranged the belts so that the water pump was being driven from the slack side of the crank, not the tension side. (That same belt drove the Sanden AC compressor over on the driver's side.) That poor arrangement resulted...

    I think I found my vibration problem

    Just an FYI, TD, if it has Keith Black pistons in it, then the piston + pin weight is around 140-150 grams less per slug than the stock pistons and pins. That will reduce the bobweight by somewhere in the 6-8% range (just off the top of my head), and that will make it imbalanced... not horribly...

    vibration at 25-40 mph

    If you got rid of the side to side wobble, then the wheel is a bit bent. Look at the new wheel from the side and see if you spot any obvious vertical runout. If not, then it is just the tire shape. It may or may not be any issues; radials and any nylon belted tire take a set when they sit for a...

    Speedometer problems

    And it can do this if the new cable core's square end does not actually engage the socket in the speedo, but just rides on the surface of the socket; it jumps around and engages the speedo erratically. Sometimes, you have to pull the core out a bit at the speedo end, rotate it to perfectly align...

    vibration at 25-40 mph

    Looks like a slightly bent wheel on the right side. Swap them side to side and see if the wobble follows that wheel to the left side.

    Does the Torque Converter heat engine while idling??

    IMO, this is the most likely cause and is normal: no extra air flow inlet pressure from movement, and the fan at it's lowest speed so rad and direct engine cooling is minimum.

    Pilot Bearing hole?

    Since the pilot hole is smaller than the registration hole for the torque converter snout, and is inside of it, that seems like it would be impossible to see at all.

    904 Downshift Squall or Howl

    At this point, just about any idea is a good idea. We have been adjusting the rear prop valve out as we improve the brakes; it may be all out by now as we put in higher CoF front pads and adjusted more prop valve reduction back out of the rears; my goals is to get trid of that thing. But it does...

    904 Downshift Squall or Howl

    OK, I did not think of the planetaries; they would be putting power back into the engine to spin it up on the downshifts. Trans was supposedly rebuilt by a shop good with Torqueflites maybe 2 years ago and < 1k miles ago, but I am not sure how often anyone would look hard at the planetaries. But...

    904 Downshift Squall or Howl

    My son's '65 'Cuda has an occasional but subdued howling or squalling sound when it downshifts when slowing to a stop. This occurs are both the 3-2 and 2-1 downshifts. The tone is kind of like the low pitched squalling sound that an 18 wheeler's tire makes when it locks up, but much less loud or...

    8 1/4 Rear "Whomp Whomp" Vibrations at High Speeds

    Good deal! Yes, very frustrating and great to fix. Hmmmm.... that is a negative to the Green bearings that I did not realize.

    What stall converter do I need?

    OK; your cam would not be expected to be 'happy' with a stock converter. I have used a stock converter OK... but only with a torque cam with 15 degrees less duration.

    What stall converter do I need?

    OK so a fun street car, it sounds like. For me, I would go as low as I could on the TC stall, just to keep the thing from spinning a lot of unnecessary RPM's to be moving along. And the reason I ask about the CR is that a low CR is going to need some help for a crisp launch, but a higher CR is...

    What stall converter do I need?

    A darned good question... the point I was trying to make to the OP was that you want to be well up on the torque curve of the cam when the TC stalls, not well up on the HP curve. For 'up on the torque curve', I go by mfr's RPM ranges; they are generally spec'd for the lower RPM end of the...

    What stall converter do I need?

    OP..... you could just go by the Lunati recommendation.....2400 RPM stall. The cam mfr's generally give a range of RPM's and that cam is rated for 1800-6200 RPM. 1800 + 500 = 2300..... The only reservation I would have on that is that at 55 mph in 3rd gear, cruising, the RPM's will be in the...

    I Give Up - Why an A-904 Rolls A Sprag?

    I had similar issues with a C4 once..... it was not engaging the right items and trans was doing the wrong thing (with no damage fortunately). Turned out the be the VB gasket to the case.

    What stall converter do I need?

    I would change the original statement to say '500 RPM above where the engine starts making TORQUE'. We have a very close to the same combo in a '65 'Cuda, except the rear gear is 3.55 with wider tires and the heads are 63 cc chambers to make 10:1 static CR. We have a 2200 stall Hughes and at...
