Check u joints for dry or worn bearings. These will often feel tight, but be worn out enough to vibrate at certain rpm range. I chased a vibration/rumble for a few years that would come and go depending on out side temperature and rpm above 3000; it was front u joint that had one dry bearing...

You may have to use your old roster comb and neutral lockout switch. At some point around 1968 that switch went from single contact and separate back up light switch to three contacts two of which control back up lights, and center is lock out circuit.

I suspect the lack of fuel efficiency increase after installing an overdrive device be it GV, a 4,5, or 6 speed transmission often can caused by a big lumpy cam that is rather inefficient at low rpm. Running a big overlapping cam that needs high rpm to improve scavenging requires a rear gear...

What brand carburetor are you using? Most brands require a Chrysler throttle pressure (kick down) cable adapter that corrects and synchronizes the two different lengths of cable travel between throttle, and kick-down. An example of a Holley adapter bracket for Chrysler here...

There was a reverse manual valve body in my Dart (former drag queen) operated via stock console shifter when I purchased it. I ran the car like this for one season, and soon tired of the goofy light handed click-click-click, first to third and back down again action with an occasional misplaced...

What folks are getting to is camshaft, torque converter and final drive train gearing have to be matched for best compromise between performance, and fuel economy. In other words if your cam positions power and torque curve high up the rpm band as most lumpy overlapping cams do, than a rear...

2. Newly rebuilt carburetor. Do you mean purchased a rebuilt carburetor, or did you rebuild your old carburetor? Auto parts store rebuilt carburetors often do not perform well as they are a collection of parts “point five rear-ended” (half-assed that is) together, and are no...

It’s not a matter of picking one, but matching torque converter to engine output, cam profile, rear gear, tire size, weight, and intended use of car. You need to know what your cruise speed/rpm is, torque curve, and idle characteristics which all can be calculated. If converter is...

You left out the imposable to read and comprehend alpha numerical phonetic spelling knitted into this incomprehensible run on paragraph… I too gave up trying to decipher post after attempting to decode a few lines. Hint to composers of this writing style; peck out your message in...

Reconnect throttle pressure linkage el'pronto, or you will burn up front clutch pack in no time. Have you properly readjusted KD or throttle pressure linkage since installing transmission? Make sure the shift cables are properly adjusted and moving through their full range of travel. As...

Mplex2000: Accelerator cable is adjusted fine now. Difficult to do because it's on the same bolt as the kickdown cable Throttle pressure or kick-down cable hooked to same bolt? Are you referring to the clamp that secures both cables to bracket, or where cables attach to throttle lever on...

4spdragtop: Stall speed is dependent on amount of torque engine makes, the weight and gearing of vehicle as well as how converter is built. Let’s say we take the same converter and install it behind two different engines a small block (lower torque out-put) and a big block (higher...

Valve bodies can be swapped between V8 and /6 904 transmissions. The big difference between /6 & most V8 904’s are the number of front & rear clutch disks & steels, V8 has one more than /6 front for a total of four, same for rear pack one additional clutch sometimes; also there are...

Bingo

Sorry I didn’t get that you were talking about just the lever and its inner guts. Look here: http://www.beaparts.com/list_items.aspx?body=a&cat=i

It must be cobbled up from another year car, as 1967 A Bodies used rods, and bell cranks to connect shifter to transmission. A photo would help.

There are all kinds of reverse manual valve body kits for your 72 904. All 1968 and newer valve bodies controlling non lock-up transmissions are mostly interchangeable.

Once you get angles figured out and corrected if necessary, check for worn tail shaft bushing that front yoke runs on.

Depending which year 360 ci engine you are using, early or late model, there are balance differences between them in addition to the miss match of spline & shaft size to a 67 and older transmission. I think all 1966 automatic transmissions are non-pushbutton controlled? In addition to the shaft...

We need more information about carburetor: make; vacuum or mechanical secondaries; size/cfm; jetting; and choke type to start. Your current cam/rear gear configuration appears to incompatible particularly if its stall speed is near or above your highway cruise rpm making it fuel hungry, and...

Aren’t 8 ¾” axel's left & right sides unequal length? Have you got the short one in the long hole?

No, torque converters stall at different speeds depending on which engine it is behind. In other words, let’s say you had a strong V8 and a converter that stalled at 3000 rpm behind it, now install that same 3000 rpm stall unit behind a stock slant six and because the slant makes a lot...

Selection, or rather designing stall speed one has to consider several parameters, and a few calculations. Converter companies figure out this stuff every day. Torque converter builder will need to know engine size and build details, cam profile and its rpm range, transmission type, rear gear...

Why would you want a 4200 rpm stall converter behind a budget used stock engine out of a PU truck? Look up what was stock stall for that application, and stick with it, otherwise you will have transmission heat problems, and poorer fuel economy with high stall unit. Now if you had some kind...

Call MSD tech line: http://www.msdignition.com/page.aspx?id=4209 I'm sure thay have a Chrysler automatic transmission adapter kit that bolts right up, and accepts chrysler cables. Here is an example of a Chrysler throttle adapter bracket that one would use on a Holley...

I think you need a Chrysler throttle shaft adapter to get the correct ratio of movement between throttle cable and transmission throttle position cable. Currently your throttle cable travels more distance than kick down cable can move. You need to move the kick down cable attachment point on...

Hey Skunk, welcome aboard… We all started with no experience at some point, but that is what a brain and books are for, to use others experience to our advantage. First you need to find and purchase a Factory Service Manual, which will answer 90% of any questions you may have with the...

Yup, and then some.... 904 including converter holds 16 pints... two gallons

Off topic answer: Get a Hemi powered LX platform if you want something that goes like hell & gets good fuel mileage. My bone stock 300C AWD gets 23 mpg on a trip, and does mid 14’s @ 100 mph quietly in drive.

Try cleaning trans while still in car, and figure out where it is leaking. Most leaks can be fixed with transmission in car, (borderline PIA), or if it is front pump seal (trans has to come out for that to happen), just hold off until unit is out of the car and replace all the seals at once as...
