4r / 5r Shift Controller?

[RonD]

Need to decide on which diesel engine you want first then you can research which transmission would be best for that engine

 

[Snoranger]

This. ⬆


Figure out what engine you want then find what adapters are available... that will dictate which trans options you have.

 

[WantToBeDiesel]

Ok,
I have a friend who is a machinist, so he can make a custom adapter plate,
Just a matter of finding an engine, and I want to stick with a gm trans

 

[bobbywalter]

Great!
Are there any threads here on doing the tranny swap?

my vehicle is equipped with a diesel and a 4l80. mercilessly extracted from humvee and cucv carcasses.


it has a 3 inch body lift. with my particular situation.

i can install it without a body lift but it would suck to work on it. it suks to work on stock trucks without a body lift for that matter.


2wd ? 2 or 4wd and your goals are needed...

 

[WantToBeDiesel]

Yes, mine is 2wd. I want to have a fun, fuel efficient comuter truck

 

[WantToBeDiesel]

So how does a 6.5 diesel fit??, seems like a tight squeeze

 

[bobbywalter]

well...1.9 alh or the later 2.0 vw are outstanding platforms for a 2wd. the 4l60 oreven a 3 speed would be ok.


with a stock 1.9 keeping your 4r55 will probably be fine. getting the signals from the diesel to run the stock pcm is not likely easy....but utilizing the edis it may be possible to hack it together with just driveway ingenuity.

 

[bobbywalter]

its a matter of compromise and goals.

this allows you to run a gm trans....with a vw engine the 4l60 or 700 r4 would be easy. run a truck megashifter and conversion joint on the modified gm drive shaft or vice versa on the ford.

you can have a all mechanical setup with the 700 and if you want an auto likely the best bet.

 

[WantToBeDiesel]

Ok,
How about a 1.6 fully mechanical tdi?
I have a lead on a good runner for $150

 

[WantToBeDiesel]

Also,
How do I choose my shift points with a 700r4 if it’s not computer controlled? How does a megashifter work? Is it like driving a manual without a clutch?

 

[Snoranger]

Changing the governor springs and weights will change the shift points. They sell kits for it.

No, it's not like driving a manual... it's like driving an automatic with a floor mounted shifter. Yes you can manually shift gears, or just put it in drive and go.

1.6.....pretty nutless.

the alh i have seen work very well with minimal mods.
