Yes.

Sooooo...does it seem like it's more of a running/power issue?

 

@The Deputy

Trans fluid was changed right before I bought the truck - I do not think the filter was changed. That was 2000 miles ago.

When the mechanic installed my new front driveshaft he removed a trans cooler line and lost some fluid. He refilled it to the proper level - engine running, etc. The described issues was already happening before he put the driveshaft in.

So NO filter changed, and level checked with truck ON.

Something I did no describe well: It seems to upshift way too early, and then when it kicks down a gear, it shifts fine, but it shifts from gear to gear very quickly like it cannot make up its mind.

I do not think it is a running/ power issue, at least I have no reason to think that. It revs smoothly, and when it holds a gear it pulls well and runs smooth/does not overheat. No SES light.

I have another thread going about a separate, but possibly not unrelated issue: https://landroverforums.com/forum/di...-ideas-101064/

I agree that draining fluid and changing the filter, then properly refilling is probably the next best step. It has not done this except for the past 150 miles or so.

 

@The Deputy 154,000 on the truck. About 80,000 on the P38 4.6.

 

I tried the torque converter stall test on my way home today, just to see what happened. Truck revved up to right at 2,000 rpm before stalling.

The RAVE manual states that a rpm reading during the test between 1300-2200rpm indicates reduced engine power.

Is this an indication that perhaps my issue is power delivery related, not necessarily the transmission?

 

I performed the torque converter stall test again, to verify yesterday’s results.
today.

Today it revved eagerly until 2250rpm. The stutter feel like the drivetrain to me, not a misfire.

 

2010 LR4 @ 187k here with the exact same thing happening. Was any resolution found?

 

Pretty sure that an LR4 uses a completely different transmission than a Discovery 2, so this forum may not provide helpful answers for you. (The is the D2 forum.)

 

My 96 D1 does this too. Maybe has something to do with how the shift point is programmed? I bought a new CPS to swap in as an experiment based on input from the Forum.
