360 Magnum

[Bruceynz]

Passenger side header on, that was nice and quick compared to driver side. So my weekend is over 10pm Sunday night and I am over working on old cars until next weekend! Also worked on my gardens and lawns, took a trailer loads of weeds and lawn clippings away!

A little more progress, whats the best way to fill up the trans, or just a funnel and away you go?

 

[FredMcJoe]

Stop adding transmission fluid when you have some registering on the stick, then crank the engine to pump the fluid into the torque converter, then add oil to full mark on stick. Check again after the transmission has come up to operating temperature.

Nice and neat

whats the best way to fill up the trans, or just a funnel and away you go?

A tall skinny funnel is about the only way to fill it, like this one.

I use another one to fill with engine oil, like this one.

The official instructions to drain and refill an automatic transmission. In this case, pay no attention to the drain aspect. The Fill part does apply.

From my '77 FSM.

The official instructions to drain and refill an automatic transmission. In this case, pay no attention to the drain aspect. The Fill part does apply.

Note: my ’86 FSM says exactly the same - except to use “MOPAR ATF+ Type 7176” – instead of “DEXRON”.

Note: in 2007, Chrysler changed that, to say to only to use “ATF+4 (Type 9602) – in all Vehicles that came with DEXRON, ATF+, ATF+2 or ATF+3.
That is unless your specific transmission builder/supplier says otherwise.

Edit: Note, the "drain torque converter" procedure only applies to vehicles made early ’78’s and older cars. The late ’78 cars have lockup torque converters – which you cannot drain.
Even that, I have seen some mid to late ‘70’s pre-lockup converters that do not have a drain plug on them.

How may quarts will a 904 hold with a deep dish pan?

 

[BudW]

Using a normal pan:
Lockup 17.1 pints (8.1L)
Non Lockup 17.6 pints (8.3L)

I can’t comment about the deep pan fluid usage – for that varies on pan manufacture.

Also, an add-on transmission cooler will require more fluid (if used, that is).
BudW

Edit: Did your transmission come with some paperwork on how much fluid to use (and which fluid to use)?

 

[Bruceynz]

I bought the pan after seeing a guy on youtube recommend one, and I bought the late model rubber gasket he said to get as well, since trans run quite warm I thought the more oil in there the cooler it can run the better for the trans! All made sense.

This is the one I bought there:

Dakota Grand Cherokee 42RE Automatic Transmission Oil Pan Cover Gasket Mopar Oem

 

[BudW]

That is one of the “forever” pan gaskets. So as long as you don’t tear it, that pan gasket can be reused again and again.

Deep pans are always the way to go – depending on your road conditions. Deep pans are also easy to knock a hole into (again – depending on your roads).

Did your pan come with a filter extension, like this one? There are a few different designs of filter extensions – and this one is the most common one.

Overdrive and computer controlled valve body’s require taller pans – to get everything crammed into/inside of the pan.

Non- overdrive and/or non-computer controlled transmissions do need a filter extension and longer filter screws.
The filter extension is not a requirement – but is a lot better on the transmission to suck from the bottom of pan.

If you haven’t put fluid into the transmission yet, then I might highly encourage you to get one and install it.

I have no way to know how much more fluid that pan will hold over your old pan – without adding and measuring fluid from bolt pans, while pan is on bench.

[Bruceynz]

No It didn't is it a problem if its not used?

 

[BudW]

Yes, it can be used without the adaptor.

One problem automatic transmissions have - is the fluid. When fluid hits moving parts, it will aerate (ie: turn into pink foam). Foam – is part fluid and part air (percentage will vary), and will compress when under pressure – actually the air portion compresses, the fluid cannot.
Automatic transmissions are hydraulic in nature – with its own Hydraulic computer (valve body). Hydraulics, in general, do not like air (aerated fluid) because air has different properties than fluid has.
Also air does not lubricate, like fluid can.

Most automatic transmissions, the moving parts are normally located above the fluid level – so aeration shouldn’t occur – but it can at times (driving on an steep angle, bouncy roads, etc.) and it takes a while for the foam to dissipate.

With a deeper pan, you will have more fluid in the transmission (which is a very good thing). The dipstick will still register a fluid level that transmission needs (ie: level where fluid level should not normally contact moving parts) – so you will (still) need to use the dipstick for proper level.

What I’m concerned about that if fluid does gets aerated (ie: foamy) and sense foam floats on top of the fluid – that transmission is more likely to suck the aerated fluid, with filter up higher in transmission fluid.

Now with that said – will you have a problem with that issue?
Most likely no – unless you plan on road racing car, or perform other vehicular acts most drivers will not perform.

Yes and no
No so go figure it out for yourself.

Ok making progress, not much this weekend but looking like I am getting there, got about 1cm clearance between fan and bottom hose, should be ok if not will have a leak! Shroud a bit short compared to LA fan and last pick shows she is just about back together.

 

[jasperjacko]

Would you just get this thing running already?! the suspense is killing us. lol

 

[Bruceynz]

lol lol getting there, fuel pump to plum in the back, anyone put a holley red pump in the back for a J before and where did you put it?

Family slows down progress, I could of done a lot more but my children are 6 and 9 so they have things on (yesterday a 10 year old and 40 year old birthday party, 40th being a surprise one) I mowed the lawns in the evening all I managed to do on the car was, bottom hose, trans lines, fan and shroud. Still its couple more we jobs done!

 

[BudW]

1cm seems a bit close for fan blade.
The good news is under load, the engine should tilt in a direction that should allow for more gap – unless the hose is already contacting the K-Frame. From your first picture – I can’t tell.

If it was my car, I might loosen the lower radiator hose from water pump and pull it out a little – away from pump, and re-tighten the clamp – and see if that gives you more room.

Another trick I use – is to twist the hose slightly when tightening the clamp (which takes 3 hands to do, sometimes). Sometimes that small twist, from one end or the other, can fix clearance problems (and hose kinks) . . . sometimes.

[Bruceynz]

Have already tried the first step, it is close but I have no other options

 

[Bruceynz]

Ok, for those of you watching you will know I have been having yoke problems, so I decided to get on to the fuel pump, been something I have not really been that keen on, anyway I bit the bullet and got on my creeper and looked around for a bit, I thought if I hang a flat bar across there and then hang the pump off that I can get the pump next to the tank, at the bottom of the tank and above the diff so it don't get clouted. Check out my install, hard to see from photos but you get the idea. Don't worry the hoses have a lot of clearance, its just the angles things are on that make it look closer than what it is, in the first pic you can see the bolts on the pump, left side just sitting at tank bottom level.

 

[Bruceynz]

There we go guys, all that is left is to fill the trans with oil, time her up and hook the wires, turn the key, check for fuel leaks if none hit the starter and see what happens, so its taken 6 months but its done, rebuilt trans and a pretty major over haul of a 360 magnum!

 

[Bruceynz]

You know what its a big job changing engines and trans over by yourself, can anyone recommend a good way to bed in the rings, I see on youtube just take to 2000, in each gear then back down through the gears then repeat to at 2500, 3000, 3500, 4000, 4500, 5000, 5500 job done. Is this a good method to bed them in?
