5 Speed, Not T5

[falconvan]

Great! By the way, you've made a mark with this swap. A guy from Quincy, Il contacted me on the HAMB and drove out here to buy some 49 parts from me. We were talking shop and he asked me what drivetrain I was going to use in my 51. I told him about the Ranger trans and he said, "Is that the swap the guy from the P15 site came up with?"

[Robert Horne]

I am very happy if I can make anything better or easier for anyone interested

in our Mopars. I will make another rod to replace the clutch pedal

adjustment rod. I have one that is a little too long, about 1/2 inch, and

another one, about 1/2 not long enough. I believe this is why I had to

use spacers between the pressure plate and flywheel. The way it is now,

it is working great....

[Robert Horne]

I had my Coupe out a couple of times today. The 5 speed trans makes it a pleasure to drive. 3rd and 4th gear makes the small curvy, up and down, roads easy to drive on, especially with only 80HP. 5th gear is doing good on level roads also. The 3.90 rear gear is an ok combo with this setup in this car. I have a 3.73 I can install this winter, but I am thinking this may take away too much from my topend. More test driving is necessary....

about 9 MPH less at same rpm if you go to 3.73 in 4th 1.1..od about 12-13

[Robert Horne]

Thanks Tim. I am not to fond on driving on the Interstate, so I will be doing some test runs and see how the car does at 55MPH. I have a GPS unit that should be fairly accurate. I am not sure how accurate my tach is, but I have a second tach I will install also.

[Plymouthy Adams]

my error in the OD statement..was saying one thing and typing the answer for the inverse..

if going from the 3.73 to a 3.55 you get another approx 8 MPH 4th at 1.1 and 10-11 with OD at same RPM..

going to 3.73 from 3.55 will be a loss of approx 8 in 4th 1.1 and in OD you will still gain about 2.4 MPH so effectively you will lose only 5.4 MPH..same RPM...I never did like math...

If Rob and Bill were 3100 miles apart both left home doing 55 MPH and their destaination is ......

[Robert Horne]

I have not checked my 38 Coupe rearend ratio for over 10 years,
and my memory is not very good, so I checked it again.
The Coupe's rearend ratio is 3.9, I guess.
I was thinking it was 3.4 or 3.5.....
I turned the drum two times, and the yoke turned 3 and almost one
more complete turn.
Anyway, the 95 Ranger rearend I was wanting to use, is a 3.73
stamped on a tag.
Since the 5 speed's first gear is almost like a "granny" gear, the 3.73
would be a little improvement.

I have a 1985 Ranger with a 3.23 rearend. maybe too high though.

This is my adapter I made to use a Ranger temporary driveshaft on my 38's rearend, 3.9.

I shortened the Ranger driveshaft to 41 inch.

This setup is working good for now, until I can find an Explorer rear,

or install the Ranger rear, 3.73:cool:

Now that"s thats thinking outside the box and a great solution to mis-matched components. Do you have any issues with vibration.

Karl

[Robert Horne]

No vibration so far.

[fstfish66]

hope the drive shaft isnt to short now,,,if you switch to the ranger rear axel,,, but as stated great thinking out side the box,,

[Robert Horne]

I added about 7 inchs to my floor shifter today.

It is alot easier to reach now.

[Robert Horne]

I recently install a 1995 Ford Ranger rearend, 3.73, into the Coupe.

I checked the angle on the old rearend before removal.

I made up a simple track bar also.

I drove the Coupe about 20 miles or so today. Car drives great now.

The 3.73 is a good improvement from the 3.90 I removed.

[falconvan]

Looks great, Robert! You should be ready for any length of a trip now!

I have read it a few times now and I have some quick questions.

1. i know you said you don't like highways but what kinda top speed are you getting? I am removing a sbc from my car and going back to a 230 flathead. my current plans are 230 with a cam,fenton headers,finned head,and dual carbs. and i for sure want to be able to get on the freeway. just wondering what kinda speed your turning at say 65-70?

2. do you have part numbers for the pilot bushing?

i am really excited about this and not having to spend the coin on a t-5 adapter.plus i have friend that is building virtually the same motor but with a stock head different intake (still dual carbs) and a t-5.so it will be fun to race!

[Robert Horne]

For the pilot bushings, check out post #77. I bought two different sizes, pressed the smaller one into the larger one. I have two of these transmissions, and the pilot shaft was a little different on each by .002 or so.

My engine is a 218, maybe 80HP or so. I recently got my speedometer working, I have a tach, and a GPS unit, so I will do some test soon to see what the speeds and RPMs are. The first gear is a little lower than stock, and is very good to go up my steep driveway.

On the back roads here, at 40MPH in 4th gear, the RPMs are around 1700 or so. Will get some more accurate numbers soon. I believe the little Coupe will be ok on the Interstate now.....

[Robert Horne]

When I installed the TK5 trans, I shortened a Ranger driveshaft to 41 inch, and attached to the Plymouth rearend, 3,9 using a aluminum adapter I made.

Coupe did ok, no vibration at 40 or 50 mph.

Later, I installed the ranger rearend, 3.73, and cut down another Ranger

driveshaft to 43.5 inch. The Coupe has a vibration starting at 40mph.

I figure my 43.5 shaft not balanced, just got lucky with the 41 inch.

Yesterday, I installed a 43 inch shaft from an Explorer I believe.

I have a vibration starting at 50mph how. I am thinking I did not do a good job on the Ranger rearend install, angle not correct. I put the angle at about 2 degree.

I was thinking also, maybe my "floating power motor mounts" have sunk, (old, and hard)...

Back to the drawing board...

[Plymouthy Adams]

the trick is parallel imaginary lines..what is the angle of the tranny output shaft, hopefully down? and the angle of the rear you say is 2 but is that up or down..and what is the angle of the drive shaft when connected (x length at x rpm per x angle)....next, is the imaginary line front to rear of both devices...are these parallel..

while checking these figures is geat idea..do not rule out the shift of the rear axle due to say bad bush on one side copared to good on the other..or even for that matter one weak spring will jut your shaft at a slight angle..combine with a bit of mis calc can put you in excess

[Robert Horne]

I believe the angle on the trans was 2, and the angle on the rear was 2, before I removed anything when I was running the stock rearend.

I will have to go back and recheck everything.

Before I installed the ranger rear, I spent some time and changed some of the leaf springs to get a better balance from one side to the other.

The Coupe was a little low on the left before, is ok now.

[Robert Horne]

We had a little sunshine here in Virginia today, so good time to put on a couple of miles on the Coupe.

 

Ranger rearend, 3.73, is a good addition.       Coupe cruising good at 55....

 

I will borrow a GPS unit and get some RPM, and MPH numbers soon.....

[falconvan]

That's cool, Robert. This is a great swap you came up with and will save guys a lot of dough.

[Robert Horne]

Thanks Falcon,

 

I am on the hunt for another type trans,,,Mitsubishi FM132, code D 5 speed,that came in 1988 to

 

1992,,,2.9L 2 wheel drive Ranger..not sure of the gears, but the 4x4 had, 3.769 to 0.812...

 

A friend of mine has a 52 Studebaker truck, all original, 6 cyl, in family long time, has a bad trans

.

I am trying to help him adapt a 5 speed of some type,,,T5,,,,TK5,,,or FM132, etc....

[wayfarer]

Robert, what input shaft length will the Stude bell require?  There are many 5/6  speed units to consider but alot of the 'little' guys also have a fairly short shaft.

[Earlsworkshop]

I have to ask. Has anyone attempted to do a 5 speed swap using a trannie from an early Dodge Dakota?

While searching for a T5 online, I saw this one pictured on Ebay and thought that it could be a good candidate to replace the 3 speed in my '36 Dodge 4 door.

It has a shorter tail shaft than the S10/Mustang/Camaro/Firebird T5, and it has the shifter forward on the tail housing like the S10 T5.

The bell housing does detach from the gearbox, but I haven't seen one up close to compare bolt patterns. It does appear to be closer to the Mustang bolt pattern than the S-10 bolt pattern.

 

I also saw a couple of newer Mustang 5 speeds that looked interesting.

A 2005

 

And a 2006:

I think these two are actually NOT T5's but TR3650 instead. Both are also of a shorter tail shaft housing with a forward mounted shifter assembly.

But I like the fact that these have an output flange instead of a slip yoke. This makes me think about adapting an original style E-brake band and drum so that I could use the stock hand brake lever.

Any thoughts?

[Young Ed]

There is something about those dakota ones that makes them hard to use without the original bellhousing. I wish I could remember the exact details but I think something prevents them from being easily centered. Those mustang trans are interesting the second one even looks like it has a parking brake drum on it already.
