good day gents.

 

new to site, so far seems pretty informative.  thanks for that.

 

01 2500 4x4, auto. new to me since 2013.  heres the list of issues i believe to be having;

 

engine knock

delay in shifting to OD

tc lock up hunt.

trans slips on left turns(sometimes)

 

so.....with engine knock....cant remember when it started, but its been at least 9 months.  noise is constant thru rpm range.  i list this as  a trans issue as i cant/hope not/ see the engine knocking for 6 months without failing completely.  oil pressure indicator working and in normal range, 40psi at idle...thereabouts. even after driving around.  ive read flex plate failure is common...perhaps stock tc as well.  i baby this beast in hopes i dont 'find' the problem accidentally.

 

my delay into OD....well, if i let off pedal, completely, is shifts into OD.  otherwise....ill have to wait til at least 55mph.  lately its been closer to 60 before it shifts on its own....just about 2k rpm.

 

the lock up hunt....recently started after a starter replacement.  i disconnected both batteries.  i remember seeing here....that if both are disconnected, an apps reset is a must.  how would i know if it should be reset?  truck seems to respond as usual.  i see a test for tc lock up hunt is to pull the alt. fuse.  i have yet to test this.  im optimistic.

 

the trans slipping on left turns....weird eh.  so on first thought....trans is low on oil.  check dip stick....in neutral...says is at max level.  i do have a mag hytech pan on it.  not sure of size...looks bigger than stock.  dip stick says im good on oil....even with larger pan...and slips when making left turns.  so....i add oil.  about 2 qts.  slip goes away.  doesnt seem to add up to me....trans temp hasnt gone past 180...i believe sensor is in a port on side of trans.  ive read lots about best place for sensor....but thats where it was when i got it.

 

i am new to ....owning ....a diesel.   i havent done much work on truck since ive had it.  starter....fixed a few vacuum leaks.  i didnt drive it much when i got it...but now...i do.  and by much....10...15 miles a day....and im shooting high.

 

anyone have any ideas?  point me in the right direction...please.  thank you.

If you have a deep pan, could the extended pickup be leaking?

Extended pick up? As in oil pick up inside pan? If so, I have no idea. I've never dropped the pan. It is a deep pan....but not their deepest. Not sure if it needs an extension. If it does and it's not deep enough in fluid...it would make sense that it slips are turns.

Extra deep pan with standard pick up would mean lots of fluid in the bottom no reachable. And deeper probably means more slosh too. For your sake I hope that's the problem.

I took hope it is...that's an easier thing to fix.

I'm still a little puzzled. Let's say it's a 2 qt sump. So 2 qt more than stock.

You add the 2 qt and now your back up to the level where it would be in stock form.

If it sloshes...it should slosh in stick trim and with deep pan. Also....how does the dip stick still read full??

I don't know what it looks like inside...I can imagine pick up being submerged all the time. Perhaps the point where it connects to valve body has come loose,separated...or leaks? This would behave funny with ant size pan...right?

No extended pick up just an additional few quarts of ATF to help manage temps a bit better. I also have one from Mag Hytech

Exactly what I thought!

Now, is it possible to have some kind of leak where pick up attaches the VB? I don't know if it's a press fit or bolted...

There is no pickup besides the transmission filter attached to the valve body which if memory serves me right it is always bathing in ATF.
