In our '65 Valiant Signet convertible 273 Auto, the speedo works and the tenths on the odometer move like they should. However, the tenths never move the next mile digit so the mileage always stays the same. I removed the speedo and can't see anything wrong from the outside. I doubt there is...

The longer the '65 Formula S sits idly by in the garage without running, the wetter the floor becomes directly under the rear seal at the end of the tailshaft of the original A/T. Drainback from the torque convertor is probably a factor. Regardless, can the seal be replaced without removal of...

The rebuilt 904 in the '65 Formula S is leaking some overnight on the garage floor (from bottom of bellhousing/convertor cover) While idling outside in the driveway, I don't find it dripping. Is that considered "normal" and is it safe to make a roadtrip in this condition? Thank you.

I know a grinding noise is a symptom of a problem. The 8 3/4 differential swapped into our '65 Formula S turned out to need a rear axle bearing replacement after hearing such a sound. But the clickety, clickety I now hear after pulling the brake drums and turning the axles by hand (this is from...

History: 1965 Plymouth Barracuda Formula S purchased not running. We found the transplanted 318 had a hole burned through the top of one piston. Stock rebuild was done on the 318, re-using the factory AFB and a 1966 four-barrel 273 intake manifold that was installed on the 318. After having...

Just putting things back together on the '65 Formula S and have found a quirk that is going to be a big pain: Although the floor shift cables are both adjusted to perfection, the transmission haphazardly will not release the park sprawl (or whatever you call it). This permits the 904 to engage...

A local Mexican transmission shop "re-built" the original 904 in our '65 Formula S some months ago. Just today got it all buttoned up and see "minor" drips front and rear: a) from the tailshaft (bolt on ball and trunnion set-up) and b) from behind the flexplate cover. I'm not mentally prepared...

The '65 Formula S had a transmission "rebuild" here in Mexico during the recent body restoration. After re-installing the engine/transmission, the vehicle sat for a few months. I could roll it in and out of the garage by placing the console shifter in "N" (neutral). When I installed the...

When I found out in my recent reading that the earlier Torqueflites (with both front and rear pumps) use a different filter than the newer Torqueflites (sans rear pump) I was curious about the transmission I just had rebuilt (factory original 904 from the '65 Formula S). Today after the engine...

My local welder made a wooden "jig" and hammered some sheet metal into submission. The primer red one in the photo is factory, the unpainted items are fabrications (I have three 904 equipped Mopars ('65's and '72) on site and two were missing (of course) this lower cover.

Beach Boys: "First gear, it's all right (Honda, Honda, go faster, faster) Second gear, I'll lean right (Honda, Honda, go faster, faster) Third gear, hang on tight (Honda, Honda, go…" But our 904 don't have first gear. Installed '65 Formula S floor shift 904 cables (sans motor) and cannot pull...

Just read on another forum a post by SlantSixDan (someone who really knows his stuff) that the early torqueflites with both front and rear pumps use a pan filter with two openings (one feeds each pump). A Fram part number is FT1015A (see photo) which I find are not available during all of my...

Only Drive Line Service in California knows at this point. While cleaning up my converted ball and trunion driveshaft (was converted over ten years ago now), I noticed an area on one end where there is the shadow of a former balancing weight. For now, I observe one washer welded onto each end of...

Before I re-install the 904, I would like to re-torque the bolts that I can reach that are located on the outside of the transmission. However, I don't know the name of the bolts in the photo (The green masking tape is alongside one of the bolts in question). What in this circle of bolts in...

Top dipstick is pulled from a '65 Valiant Signet convertible, middle dipstick is pulled from a '65 Barracuda Formula S, bottom dipstick is pulled from a '72 Satellite Sebring Plus. I used to think the only thing wrong with the convertible dipstick was that the upper handle portion was missing...

Before I stripped the '65 Formula S, when I engaged reverse with the floor shift, oftentimes I could hear the clickety, clickety, click noise of the transmission park mechanism not fulling releasing as I backed up. When I put things back together, I hope that problem does not persist. I assume...

Are these dust covers the same for both 10" and 11" torque convertors? Is this cover just bent or is there a tab or notch in this location for the smaller lower second piece? Thank you.

1965 Formula S speedometer has never worked since purchase ten years ago. Today I pulled out the speedo cable for the first time. Spinning the dash end of the cable by hand, the pinion end (17 tooth) that fits into the transmission does not turn. Well, it will turn a tiny hair amount just barely...

My Formula S 904 has an all-metal speedo cable (photo #1). Are the aftermarkets all plastic now? Should I keep using the old one? (speedo on the dash probably doesn't even work right anyway) If I remove it from the transmission, what kind of seals/gaskets/o-rings will I find inside? I was...

Is this hole behind the torque convertor supposed to be open like this (see photos)? It is very shallow. Thank you. And did the factory paint the automatic transmissions at all before they were installed in the vehicle? Thank you.

Took the '65 Formula S Torqueflite to my transmission guy to perform a basic rebuild. Obviously, we found some smooth clutch plates. However, he said he had to use needle nose pliers to straighten some clips inside the very heart of the transmission to remove some kind of cylindrical roller...

Before I install the engine/transmission after a rotisserie paint job, I think it would be a good idea to replace whatever seals can be changed without disassembling the internals of the transmission. Is there a kit available somewhere? Vehicle has factory cable-operated floor shift if that...

Leave it alone, hammer on it, replace it? Looks to be a little out of whack. I always thought those things were "self-repairing", meaning with just a little abuse they just spring back to normal on their own. I guess not. Thank you.

This local shop has an inventory of various dead rear ends.

I was cleaning up parts from the "489" case differential that a previous owner installed in our '65 Formula S. I noticed that two u-bolts are threaded for a distance of 2 3/4" (top of photo) and two others for only 2 1/4" (bottom of photo). Both pair are flattened and have the knurling where...

I found a 489 case differential, open-no suregrip, in the '65 Barracuda Formula S I purchased about ten years ago (photo one-sorry not focused). Now I find a bolt broken off inside the driver's side pinion snubber bracket (photo two). And the hollow differential vent bolt won't thread into the...

My old '65 Valiant bracket car had the factory ball & trunnion type front u-joint. Never blew it out (but once I did shed all the teeth from 3rd gear of the A833 during a power shift). My two current '65 Plymouths (Formula S and Signet Convertible) have had the ball & trunnion converted to the...

My first trip to Fremont Raceway (circa 1974) in my '65 Valiant four-door (stock 273 auto) went for naught when the tech inspector found the vehicle had no seat belt. I returned to Fremont at a later date, now with the seat belt. While waiting in the tech line, a guy who worked for a local...

The very first number is hard to make out, could be a 2, 3, 8 or ? May or may not be the original 904 in my '65 Formula S: ?? 466144W 1578689

Cleaning up the 904 Torqueflite from my '65 Formula "S" today. Don't know if it is the original factory installed transmission or not. My question is regarding some writing on the tailshaft in red letters. Can anyone interpret what it says/means? (last foto is upside down) Thank you.
