Hello everybody.
Please, can anyone out there help me with this?
When shifting to reverse, my car does it very harshly. The engine revs
fall abruptly from about 850 to 500, then it goes up to about 700. Also
it takes about 5 seconds to engage when shifted to drive. I have to
shift to 1 to have it engage immediately. Once in drive it shifts normally.
Engine and transmission mounts are new.
Is my transmission in very bad condition, or is there somewhere else I
have to check in the engine?
It had a very erratic and misadjusted idle, but solved it cleaning the
BPT and the tubes that connect it to the EGR. Also cleaned the thottle
body. Now the engine idles according to specs and is stable. However,
the way it engages the reverse, it is quite bad.
I have searched the net for a few days with no encouraging or optimistic
answers.
Please, please, help me.

As a rule, auto transmission internal pressures are always greater when
shifting to reverse. However, the slow engagement into drive indicates
a problem. Unfortunately, your problem could be caused from, but not
limited to:
Improper fluid level.
Restricted filter.
Malfunctioning pressure regulator.
Excessive clutch debris (asbestos) clogging and gumming valve body
components or servos.
My feeling is you should check the easy things like fluid level and
evaluate the fluid condition. Good fluid has a reddish tint and has no
burnt odor. If these things check out... you'll have no choice but to
take it in and let them evaluate.

I replaced as much fluid as possible yesterday (flushed out 12 quarts of
transmission oil). Haven't replaced the filter. I somehow doubt it could
be a clogged filter, but, you never know, so, I will have to take it
out. At least, now the oil is very clean, and it is at the correct level.
Thank You Professor for your feedback. Any comments and suggestions are
very welcome.
