Thanks, I thought it seemed not normal to me as other newer automatic vehicle I observed holds their engine rpm as soon as the gas pedal is lifted. Mine is a diesel version, td27 turbo specifically.
I tried also doing turning off the overdrive, but it seems it does not have any noticeable engine braking. Though it's certainly stupid for the tranny to go overdrive on uphill.
Instead, when the OD is off, I feel the engine rpm kind of neutral? Pressing the gas, rpms rises up but the vehicle is not going faster. So when the OD is on again, instead of that neutral feeling, it just slips, and very sluggish acceleration. It occurs at 1-2 upshift
This tranny seems to hold problems, like having no 2-3 upshift or 2-4 upshift as if this tranny has no 3rd gear or 4th gear, forget 3-4 upshift, all happening on D gear selector and also there's the 1-2 upshift neutral. In fact I select 2 on the gear selector as my normal driving mode as 1-2 upshift is fine, though it does makes me run at lower speeds. It also likes to leak atf at the bellhousing, near the starter motor. It certainly makes me hate to work underneath as everywhere I touch, I would have that dirty sludge.
