Open Question

Transmission missing D4 shift

My trans shifter only goes from 1-3 then skips D4 and goes to D5, why is D4 not working and not showing up on the dash when in use. There is no difference in the D5 and D4 shifts for some reason, all work fine with no skips, just doesn't show D4 on dash and no change in trans "feeling."

D4 or d5

In your Lincoln LS, you will have 3 transmission options to choose from. The first is the SelectShift, which operates similar to a manual transmission but without the clutch. The other 2 are the D4 and D5 options that you are referring to. The number after the D is really a reference to how many gears it will shift through. D4 = 4 gears, D5 = 5 gears. All that being said, it really should operate closer to a 4 gear transmission with an overdrive gear when the car is in D5. Think of it like the "drive" and "overdrive" in other cars. I have heard that to maximize fuel economy, use D5 for highway driving and D4 for city driving.

New 30rh transmission was installed in my 97 4.0l jeep wrangler and it shifts in all gears except for 3rd! even when it downshifts it goes through all gears but 3rd? please help

why not ask installer that.
btw , the TCM can fail and do that.
that is either a separate module or part of the PCM.

The TCM does all shifting. electronic, shifting it is.
the TCM has scan code errors, did you scan it and the PCM for errors.
if not , why not.????
2>3 shift failure.

even a loose or corroded , trans wired connector can fail.
or the tranny ground strap is missing.
saw a guy replace a tranny 3 times. and all 3 times failed.
he never knew the trans must be grounded perfectly .
his was missing, others simply broken, others rotted away.

what we do is make sure the TCM is sending the correct
voltage single 0v.12v, etc. to the transmission solenoids.
if not, the TCM is bad, or is in limphome. or inputs wrong.

TCM have what is called limphome that can skip gears.
my 4speed skips 2nd , in limp, by DESIGN !
all this is covered in the FSM, why not read it.
or look at it's there too.

i also have a switch box, i made., that attaches to the tranny
allowing me to make a manual transmission,
if that works the tranny is good.

the TCM will in fact mess up if its inputs are wrong
just like all computers do.
inputs are, TPS, VSS1 , VSS2, engine heat. shift selector switch PRNDL , and others.
The TCM shifts by the state of inputs. period

one cool thing, some cars pre 98, or so
the TCM is separate box. and with it unplugged
the shifter is now a manual transmission car. (for test or?)
have friends driving like this for 3 years.

When do I use the d 5 gear in acura 2003 tl 3.2 liter

Pretty much all the time!

D3, D4, and D5 are all just *DRIVE* like on any automatic transmission, EXCEPT
that the number next to the D is the "highest gear the automatic transmission will go into".
The Acura just gives you a choice, in case you don't want to go into a higher gear (like if it's slippery traction or a steep hill, etc.)

1 means: Manual gear. FIRST GEAR ONLY.
2 means: Manual gear. SECOND GEAR ONLY.
D3 means: Use automatic transmission, but engine will never shift above 3rd gear.
D4 means: Use automatic transmission, but engine will never shift above 4th gear.
D5 means: Use automatic transmission, but engine will never shift above 5th gear.

Transmission lugs in D5 gear at low speed, low RPM.

If a competent transmission shop said you need an overhaul the you need one.

Transmission not shifting on its own.

check the shift solenoids by using a OHM METER .the both solenoid connectors has 2 terminals 1 and 2 .take ohm meter measure terminal 1 resistance to body ground it should be 14-30 ohms.if less or more replace it.then number 2 terminal to both the connectors that you disconnect.they should be 14-30 ohms.if less or more replace them.if they check out good .your valve body in transmission is going have to be removed.
