I had a '68 AMC Javelin with the hideous Warner M12 automatic and 343 V8 engine. That trans pooched and the engine had worn cylinders and a drinking problem. So I swapped in a '77 304 and a 74 A904 that Chrysler was selling AMC at the time and to boot a " Trans Go " shift kit. Never had so much fun with a drive train combo. Could chirp the tires in the 2-3 shift and it sipped gas. It did so largely due to the 3.15 ratio rear end, but the drive train was bulletproof.

Best transmission ever made.

I rebuilt a few of those back in the day. Very lightweight, if you wanted a hot rod you'd get the A-727. I sure wished they'd left the drain plugs in the torque converter and the pan. No matter how careful I am I still get a puddle of ATF on the floor.

Amusing voice for "Tech" .

Great video, thanks for sharing!

I like how they did not change too much. My lady got a 1986 Fifth Avenue with the 318 and 904. I think I am missing the drain plug and not sure if I got a converter drain bolt but I have no way to check without dropping the trans me thinks. What a cool old video to see how them old transmissions were made. My old lady's Chrysler has about 200k on it, doesn't use any oil but the car is kind of falling apart haha even still it will out last all these gen III hemi junkers. Its still running original power steering pump and alternator, trans motor rear end everything. I did some small fixes to the vacuum and air pump has gone bye bye but other than that its about 95% all original

lol They aren't referring to Chrysler Imperials, but imperial (UK) measuring systems. One US quart = .83267 "Imperial" (UK) quarts. Kinda like comparing to metric. Same amount of fluid, just measured differently.

Nice 🎉

As a former Chrysler technician, nice to see they continued the corny acting well into the 2010s. Only now with color photos with a guy pretending to work on a car with not a drop of dirt or grease on him and a freshly cleaned uniform

I've had 5 vehicles with 904's and 4 out of the 5 failed in normal driving. On three of them 3rd gear suddenly went out and one lost reverse. I've also had several 727 torqueflites which were problem free. All the 904's were mated to 318's.

That throttle linkage looks like a disaster.

tech looks like vault boy from fallout

I just bought a full size giant 1978 Chrysler Newport,,360 CID engine,,V8,,. I was surprized Chrysler used the 904 transmission ! My mechanic was surprised too. Does anyone know why Chrysler cut corners back then?

At 6:22 Tech should've said transmission fluid pan.

Why do you put less fluid in Chrysler Imperials?

Got that?

These actually had a better sprag(one way clutch),held rear planet for low gear(takeoff), These were called "Baby Torqueflites", But in most trans builders opinions they were better than 727 longevity wise!. 727 had a problem in several areas,clutch material flaked off BAD!,Rear band(reverse&engine braking) broke frequently,reverse servo broke,Non Hemi case need sprag replaced with bolt on type those sprags would NOT take neutral slams or a lot of HP suddenly....SNAP..GImive me a 904 everytime!.

witch is better 904 or a727

Swear I had this three speed in my 78 tradesman van..

I put the t6 behind the 427 Camaro and watch the parts fly out at wot

Almost sounds like Alex Jones lol
