New Passon 5 Speed

[72hemi]

For those that haven't checked moparts, check out this link. The new Passon 5 speed information. This unit is going to be a direct replacement for your 833 4 speed (18 spline) which is totally awesome! The downside? The cost, comes in at $4300, ouch.

Ya i want one.

$1300 more than a comparable Keisler, but at least you won't have to hack the floor and have weird driveline angles.  That's worth the extra cost IMHO.

Only ***** is that if you're converting from an auto, you have to come up a four-speed crossmember and a driveshaft, whereas the Keisler comes w/that.

I like the OD ratio better.  .70 is better than .64 or .82 in the Tremec.  Wonder if there's a warranty.

Not too crazy for It After seeing the transmission gearing..

2.64
1.92
1.40
1.00
.70

The shift points are all funky........... with  a 26inch tall tire...and 3.55's,  with 5,500 rpm red-line, wouldn't work in my combo.

Also 2nd to 3rd looks short no matter what rear gear/tire combo you do.

Might be able to get away with a 3.73 and a 27.0 tall tire with this trans...

First                  44.35 MPH           @     5,500 rpm read-line.
2nd Gear            61.67 MPH
3rd Gear             84.57 MPH
4th Gear            118.4 MPH
5th Gear            169.14 MPH

And 5th (.70) is not that great for highway driving..............

With the cost, I will continue my original path of cutting the floor and installing a Viper 6 speed. I can do the entire conversion for less than the price of this transmission.

[Cooter]

Yep, knew this was gonna be pricey.....Maybe Passion will sell 15 bazillion units to the well off croud and the price will come down to around $1500.00 per trans so us lesser folks can go 5-speed as well...Doubt it....

[72hemi]

I realize that creating a 833 based 5 speed overdrive manufactured here in the states is going to be expensive, but 50% more than your compeitition is going to make it difficult for most to justify I think. The idea seems to be that people who have super rare cars can now install an overdrive without modification to there cars (ie hemi cars and wing cars), but odds are most of the people that own those (with certain excemptions) will trailer them any distance where an OD will be beneficial, so I don't know. Great idea, but whether or not it will be successful I guess time will tell.

Only ***** is that if you're converting from an auto, you have to come up a four-speed crossmember and a driveshaft, whereas the Keisler comes w/that.

Assuming it mounts the same as a stock 833, the x-member shouldn't be a problem. Auto and 4-speed are the same on E-bodies. Driveshaft length is the same for a stock 4-speed vs. a 727 as well.

I just love all the gearing experts on here...I think any one who nay-says this product is clueless.  Show poodles rule.

This is a great moment for those of us that drive these old cars.  Hello it's called driving. Cars are transportation, not investment or "art".  As always there's whining from some one rather than happy that these old pigs get some good gearing that is a no brainer swap.

 Just stay on the porch.

The tremecs and it's illegitimate variants are just that illegitimate and do not belong in these cars because they don't fit unless you hack up the car.  Compromised hardware...period.  Look up compromised...
The driveline angle is "unusual" and  the quality of the hardware is hit and miss, let alone you are at the mercy of some company with less than stellar customer service. I bet there is not one tremec half breed out there that can survive the torture test, let alone shift clean from 2-3... if there is bring it on & put your money where your mouth is. 

[Cooter]

Damn dude, you must work for Passion Perf. or something...Nobody's puting down the company or the product, just the pricetag that's all...A $5000.00 transmission better do one helluva lot more than just give me one extra gear.....

[Bullitt-]

Just pulled up the file I have on 833 4-speed & the 1-4 gears are virtually identical....is .70 for fifth the wrong choice?....Tremec offers .64 or .68 ratios which are steeper still & .82 in their priciest road race model....Don't see what the problem is.

Personally I don't care too much for the Tremec 5 speed conversions from Keisler or Hurst Driveline conversions (although I like the shifter used from Hurst), mostly because of the transmission. But for the money I would rather cut the floor and crossmember (which now with AMD reproducing both can be relatively easily put back to stock if so desired) and install a Viper spec T56 or TR6060 and have 6 gears to run through, plus more readily available parts should something go wrong. I am not knocking the Passon transmission from a quality stand point or installation ease standpoint, because clearly they do top notch work and the transmission is a direct bolt in, however the price is just way too high for most to justify. The Hurst Driveline conversion kit (which is designed for existing 4 speed conversions) is under $3500, and it comes with everything you need to convert your 4 speed (which is more parts then just the transmission, and shows even further the price gap). For me and the 6 speed conversion I have done extensive research and I can complete the transformation for around $3000, yes I would be using a used transmission for that price poinit, but being a Viper spec T56 there shouldn't be an issue with it holding up as a used unit.

[Road_Runner]

I could wish it would be more like $3500 than $4300, but all-in-all I'm still interested in one for the Roadrunner, especially if its built to handle 600+ TQ like I heard it would.  It's cheaper than an 18 spliine hemi 4 speed PLUS a gear vendor O/D which I was also considering so there's that.  .70 O/D would work well with the 4.10 in the Dana I have for the RR, with a 2.87 final drive very conducive to highway cruising.   I don't have the $$ to do this right now anyway, so I'll sit back and hear what others think about it in their cars.

Those are awesome ratios folks. They don't get much closer than that. 5th is just a cruiser in my opinion. I have the Passon 4 speed Hemi Od and am happy with that and that is what I will stay with. I only have 2000 miles on it

[Moparal]

It's great we have all the options now a days to be able to be selective as far as performance.  If you want it, you buy it.  It may be pricey, but made to last, race and cruise.

[ragtopdodge]

Also to consider, a car cut up to fit a tremec will lower resale value probably more than the $800 difference in price.
