Not totally Bob. If the gear ratios are almost identical with the exception of a granny gear, then what's the gain? Unless you just REALLY want that granny, it's a LOT of work for essentially a ZF-5 with Granny gear.

Now I'm not saying don't do it. I, for one, would love to see the swap go down. I've only read hypotheticals, but haven't seen an actual swap done.

 

Here's at least one guy who's done it and seems happy with the result. I like the lower first gear, don't know if it's really what I'd call a granny gear, for starting out on hills and also I think reverse is a bit lower geared too? You must like yours in your SD?

And, I don't know that the swap is all that much harder and more expensive than a ZF5 swap.

Thanks for the link! I'll read it this eve. And yes, I LOVE my ZF-6. Hey, if it is no harder, do it! I'd even help if I lived closer. But yes, the LOW gear is akin to a granny, I think so anyways.

 

Same here!



Looks like if you stuffed gasser gearing in the Diesel case, you would have a pretty similar combo. I kinda like the idea of the near 3:1 second gear for normal starts.

 

 

Seems from that thread Bob, it's definitely worth it for a few reasons. No carrier bearing would be a major one!

 

I use my 4L when I need to back up slllooowwww.... but I'm also an auto so what do I know

 

I do the same thing. People seem to forget those gears exist in there and there is no harm in using them.

 

Oh hell, I forgot the ZF6 has a better OD ratio for cruise...but now you are getting into Gear Vendor territory. I really like that idea, OD on fourth for if I tow heavy and OD on fifth if unloaded.

 

 

I sold my old E4OD for 300, it was a 2wd though. Sold the TC off my parts truck for 150 to a friend, but I gave him a great deal at that price.

I usually look at ebay for a comparable part and post it at 75% lowest value I find. That usually gets the buyer and myself a good deal, and moves the part quicker than asking full price.

 

 

Not sure if I should start a new thread. It seems to be a matter of opinion whether it's necessary to get a manual transmission ECU or get it reflashed to manual when switching from an E4OD. From what I've read one of the problems with the auto ECU with a manual clutch is that the throttle response when starting out is very aggressive and touchy. I'd also like to make sure the cruise control works OK. I think at least half the battle is getting the wiring harness connections figured out.
It looks like there are four options:
Keep the auto ECU
Reflash the auto ECU to manual
Replace the auto ECU with a manual ECU
Buy an add on chip that is set up for a manual transmission.

Right now I don't have any sort of add-on chip and it seems like it might be the way to go since I'd also get some performance options with it. I don't understand much about how chips work. Do they more or less completely over-ride the ECU or do they just over-ride certain parts of the ECU function like fueling? Over-ride might be the wrong word I really don't know much about how they work.

Any opinions on the pros and cons of buying a chip over replacing or reflashing the auto ECU?
Thanks.
