rv tranny???

[bulldog426]

what all is different between an rv tranny and a regular car tranny?? i know they say that they are a little tougher and have more clutch bands, what about gears in em?? somebody was telling me the other day that rv trannys had diffent gears in em than a regular car tranny

[passing you]

Well the tail shaft from the ones I've seen.
They had a flange output.

[dave5711]

Some RV's had transmissions that were vitrually identical to car ones. My 73 winni is like that. One piece drive shaft, long tailshaft with slip yolk

Some had a trans that was the same as a 3/4 1 ton truck trans with the short tailshaft, and bolt on yolk.

I believe some also had a version of the truck trans with a slightly differnet tail shaft for different mounting (I've seen pics but never seen one up close)

After this many years it is hard to say what gut's will be in one.

The one that was in my winni is now in my garage, while I have one from a 69 B body in the winni. I am planning pn pulling it apart, but expect to see 4 pin planets etc, since the motor is a heavy rod industrial style motor.

As far as internals, I think they are close the the same.

The HD tranny has a bolt on yolk, and a parking brake, right?

Most 3/4 and 1 tons have the slip on yolk too.

[John Kunkel]

The heaviest duty RV trans will be nearly identical inside to a 440 HP trans from the muscle car era.

[cageman]

Four pinion planetary's for sure, and an extra clutch pack.

[John Kunkel]

The Hemi was the only 727 to get an extra clutch in the front pack, all other HD units have four discs.

Wrong Again John, The 440 6bbls used the same Drum As a Hemi, and some police cars got it Too.

[dave5711]

is there any reference material to back up that?

Just curious as John is rarely(if ever) wrong on trans stuff. He has proven himself to be an accurate source for sorting out the difference in mopar folklore and fact

I guess most is a relative term.

I think this is wheel base related thing.

I've owned a few 3/4 and 1 ton's,
90% were short tailshaft with bolt on yolk. BUT all of those were club cab with big block.

Park brake was still on the wheels with all of them. I think that would be pretty old school to find one that wasn't. Would be 60's for sure.

I parted out an 80 3/4 ton reg cab 360, and yes it was a slip yolk style 727.

I was quite surprised when my winni had a slip yolk tailshaft.

I compared it to a C body I had at the time, and found the wheel bases virtually the same.

If Your Lookin For Lower Gears Someone Told Me The Old Squadcars Like 68,69,70 With The 440 Had Lower 1st & Or 2nt

The 727 used in the 440+6 is considered a "Hemi transmission", just like a Hemi 4-speed behind a 440-4 is still considered a Hemi trans. And not all years 440+6 got the Hemi 727, '69 was no different than a 440-4HP but a '69 Hemi did.

and some police cars got it Too.

Not unless they were equipped with a Hemi or 440+6. If you compare a cop transmission to others, it bears a closer resemblence to a taxi cab unit than a Hemi.

Dave ya 40years of dealers parts experierence, And The 70&71 Parts Book backs it up, and stuff we found in vechicles at the dealer.Maybe to you he s always right But i Know Better.
Also the A-833 behind a 440 was a 18 spline and was first put behind Hemi, in 1967 mopar went to it behind the 440. Thats why a 18spline is commonly called a"Hemi 4 Spd"

What part of the '70-'71 parts book supposedly makes me wrong? Don't be afraid to cite actual pages since I, too, have the book.

Show what parts in the 440+6 727 that differ widely from the Hemi; even though the basic trans has a different P/N it's a Hemi trans, the only part that is different in the two is the inner governor weight which makes a couple of rpm difference in the shift speed.

Show where in the book a 5-disc front drum is listed for police. "The book" actually states that the police is the same as the 440HP for the years '70 and '71 (Page 21-1) , in earlier years the cop and taxi trans has the same P/N. See the myth above that cop car 727's had a low gear set.

Also the A-833 behind a 440 was a 18 spline and was first put behind Hemi, in 1967 mopar went to it behind the 440. Thats why a 18spline is commonly called a"Hemi 4 Spd"

And the internal parts of the 440+6 727 are so similar that they are often called a "Hemi trans".

Dont have My 70/71 book any more John the 70?71 hemi And 440/6 used the Same Drum with a 5 clutch Disc pack, and what Chrysler Did In Production on police packages was not always as you say it,If you really worked dealer you would know that.

[John Kunkel]

Well, if you want to play the "I've seen it" game I have no response other than to say I've disassembled LOTS of cop and RV 727's and never seen anything other than what's in the book.

[moparwedge6]

Ok heres 1 for You in 1978 chrysler Built A Hp 360 4 V motor E58 They were built By Chrysler Marine in Canada and test run On Propane. They were identified By there black Valve covers. well theywere not supposed to be avail in CA.Well 1 day A mechanic walks in and says Hey aint those new 360 hp motors Supposed to Have Black Valve covers? i said Ya why, he said im prepping one rt now. thinking he was pullin my crank, isent the other parts Guy out. He says Eddie aint Crankin ya. car was ordered as A Stock unit with a 360 2 Bbl,we got a 360 e58 Volare , 727 no lock up.Rt on window sticker it said 360 2 bbl.

[John Kunkel]

So now we've gone from the "parts book backs it up" (reply #13) to "it wasn't supposed to be but I seen it".

Bet that '78 E58 had single exhaust.

[moparwedge6]

Ya it sure Did, And the 70/71 parts Book does Back it up, of Course ya Gotta Know how to Use one.

[moparwedge6]

The Hemi was the only 727 to get an extra clutch in the front pack, all other HD units have four discs.

I do know how to use it and it bears out exactly what I've said, no 5-disc front clutches in anything but the Hemi trans, definitely not in any 4-barrel version of the 727...ever.

Contradict your self much?

No contradiction to be found anywhere in my statements, as I clearly stated the Hemi is the only 727 to get the fifth clutch, wide drum, wide band, etc and the 440+6 uses a Hemi 727.

Your contention that the cop trans got them is proved false by the book which clearly states that the police trans and the 440 HP carry the exact same part number. Since finding a 440 taxi isn't likely, just compare the internal parts of a taxi cab trans when it's listed separately and you might be surprised.
