I can't do the PML due to clearance issues,but what is this Transgo you speak of.Sounds interresting.
How much,where do I get one,and why do I want one.


I'm thinking Labor Day Weekend? I wouldn't want to start a thread offering up your house though. . . Maybe we could hit up the new guy in Walker, he said he has a vehicle lift and may be interested in signing on.

The PML can be done if you add spacers to the bolts for the skid plate. There is a link on the PML site to eurekaboy doing that to his.

The Transgo is a shift kit to give firmer shifts. $62 from Suncoast.

I agree. At the risk of getting everyone hot under the collar I think the drain plug was removed to reduce leak warranty. (Another executive decision in an extremely long chain that lead to bankrupcy IMO.)

There was never a drain plug on the Chrysler 8.25,ever so no one ever removed it.Almost all the best axles do not have a drain plug,besides a very few solid axles you will not see a drain plug but on a IFS or IRS diff.

...where's the emoticon for scratching my head? ...by that reasoning, there shouldn't be one on the oil pan. ...but I can kinda see the reasoning with the assumption that the trans is only going to be drained once every 30, 50, or 100K miles or whatever people have chosen to do. I'd still like to have the drain plug though. My mom's 2000 Toyota Camry has one...comes in pretty handy.

...and yes, I see this in my company too...decisions made that only come back to haunt you later.

I had a 1996 Nissan Pathfinder 4x4 with a limited-slip rear diff that had a drainplug. There was even a kind of "notch" in the underbody to tilt up a gear oil bottle for refilling.

The very few solid axles that have drain plugs are mostly 3rd member axles which require the removal of the 3rd member to change the fluid so most came with a drain plug.The 8.25 is not a 3rd member type diff.

If you look at the Catia model, there is a green circle where it was filled in during the design phase.

Are you describing the type of axle that has a "ring" around the diff, which is an integrated piece with the housing for the axle shafts, and where the diff itself is removable - like Toyota Landcruiser axles?

In some ways it's best that the factory rear diff doesn't have a drain plug,that way you don't miss all of that good crud waiting at the bottom that a normal drain would miss. :wink:
Though I do wish I had one of those fancy covers.

tjkj,

Nice pics - I can tell that's not your KJ though - what is that?

And at the risk of starting a flame war - you seem to post a lot in the CRD sections. I appreciate your wit and your insight into the KJ - but are you sure, somewhere deep down, that you don't want a CRD?? :lol: :lol: :lol:

No not pics of mine(my pics are in the SFA section),just random pics of the internet.


As far as wanting a CRD........................

I'll never get rid of my gas KJ,but a CRD engine swap was pondered once but scrapped due to the turbo and rockcrawling(they don't mix well).

10*4. Everyone needs a good tow vehicle though. . . .

Yeah I price out a brand new Ford SD every year(about $28,000 for what I want with a diesel) but can't justify buying one till I really need one.I was brought up that a diesel should always have a trailer behind it otherwise it's just a waste of a good engine,my fathers '01 SD is over 700,000miles with the original 7.3 and trans and never is driven without a trailer attached.

Why would a turbo cause problems with rockcrawling? If the CRD engine produces more torque at low rpm than a gas (before the turbo really spools up) then what kind of deficiencies does it have? Is it a cooling issue, where the turbo could overheat and melt down? But at low rpm, the turbo won't spin at a high enough rpm nor would the exhaust gases be hot enough to cause a catastophic failure. Not sure I understand the problem. . . . :?

I agree with you that a diesel shows it's true colors when towing. Maybe a good, Limited WK CRD with all the goodies would make you a good tow rig too. I'd love to get one of those puppies, with an Inmotion ECU re-mapping for 443 lb ft of torque. . . . :twisted: :twisted:

You put him on the spot and all he could think of was the turbo. :roll: WEAK!
Come on TJKJ,you wish you had a clack clack instead of a put put.We can tell.

In bold is the whole problem,when doing delicate maneuvers on some tough obsticals having the turbo "spool up" and creating more torque then you want can be a bad thing,IE unwanted wheel spin(causing a possible tip over) or to much shock loads to drivetrain components that break stuff.About the same principle why I prefer a auto trans for rock crawling then a stick(I do know how to drive a stick),less breaking parts from shock loads which the TC will absorb to a certain point and you generally have better throttle control.

Now if I still played in the mud that's a totally different story.

Now I just have to jump in on this one. Tjkj2002 - have you driven a diesel? I understand the shock loads your talking about on a juiced-up "Other" engine, but diesels don't do that.
My Cummins doesn't, VW TDI doesn't, CRD doesn't.
Bottom line is most of it comes down to how the ECU gets programmed.
How fast an engine lights up when your foot is on the go pedal is a controllable situation. Turbo's shine at altitudes above 8000 feet on the trail.

Grew up driving them and spent 9 years driving/fixing them in the military.If the diesel doesn't have a turbo it would be great for technical rockcrawling(not rock racing like UROK and such).

Well, that's an easy disconnect on the wastegate linkage. Wastegate open = no boost. Nice mellow throttle with no suprises. Lots of bottom end torque.
