Can anybody tell me for certain if A4LD transmission internals of an AWD are same as those in an A4LD with a 2RWD?:mad2:
All else is same statictically, Engines, yr of Mfg, DSO/Plant, Type of Vehicle, etc.according to both vehicle VINs. Both these Aerostars are 4.0L Cologne V6 engines & A4LD A/Trans, etc etc
It appears to me only difference is AWD transfer is case siamesed where Tailshaft Housing bolts to Main Transmission Case on RWD. It otherwise seems all else it the same to me.
So can I take an A4LD with a crapped out Transfer Case & install an output shaft & related parts + tailshaft housing from a RWD on an AWD unit, ending up with a functional RWD A4LD A/T ? If so, I've 2 good A4LDs to use to repair 1 RWD A4LD going bad.
It's developed problems in Drive/3rd gear. Sometimes it slips out of 3rd & overrevs on light acceleration, or when accelerator's lifted slightly, or "breathed" like when in traffic. Sometimes it fails to engage D/3 coming from Intermediate/2 going into Drive/3 unless accelerator is hard peddled. At full throttle it has no problems. When in Cruise Control is has no problems either.
I hear a "new" whirring sound when it's seeking Drive/3rd @ 100 to 200 rpm over usual/ normal "upshift" rpm. Yet everything else like Lo/1st into Intmead'/2nd, or Drive/3rd into OD/4th remain good, clean, solid, normal timed, upshift with no problem or question.
Generally I drive lightly & breathe my accelerator, seldom using my brakes. I prefer to lift & fall back rather than run up on & brake for traffic ahead of me. I generally go 80-90K on brakes & pads &
seldom have drum or rotor problems. I've very few other problems also because I keep after this vehicle.:smile5:
There's no slipping, chatter, burnt ATF, worn linkages/ TVR or other normal problems. As stated above it's only 3rd when Torque Converter ought to be locking or locked.
Any knowledgeable input will be greatly appreciated here. I'm not a newbie by any means but I am definitely lost & very confuse by this problem explained above. I'm sort of convinced 1st part, about use of A4LD transmissions, either AWD less Transfer Case, & RWD with Tailshaft & Hsg are virtually interchangeable, if all else is the same. At least into a 2wd vehicle.
Obviously ECU's for AWD are lacking in a 2Wd vehicle. But I am done with AWD on A4LD Unit. My installation will be otherway.
Thanx for reading this I already appreciate you took time to.
