Yes, you have to be aware of the neutral alignment issue, but there are a number
of places on the 'Net that have detailed instructions for this. Here's one:

I found a replacement at Auto Zone maybe 18 months ago. Much
easier to install (on my 4r70w, '94 TB LX V8) than what they
had at the dealer. Under $30.

Suggest to Gerri to describe erratic shifts in as much
detail as possible. Also some indication (numbers on the
door plate ?) of which tranny on the car and mileage.

 Hi There!

Went out this morning and looked for numbers.  This is what I found on
the sticker on the door.

Body - LX2
VR -
MCDG - R
INT TRM - X6
Tape -
R - H
S -
AX - 5
TR - LCCMM

The 'erratic shifting' happened on the second test drive.  I took the
car down a curvy road with many small hills.  More than once, when
coasting down a small hill, it seemed as tho the car downshifted into a
lower gear.  This only lasted a few seconds before going back to the
top gear.  I watched the tach and the needle would jump from about
13-1500 up to 22-2400 rpm.  And NO, I wasn't over-revving the engine.
Since I bought it, I think this has happened only one time, again when
I let off the gas while going downhill on the highway.  And again, it
went right back to the higher gear.

I know the car hadn't been driven much in the 2-3 months before I
bought it.  I've had it now for about three weeks and it is almost a
daily driver.  Could the problem be from being parked for a while and
now that it is back in use, the problem is correcting itself?  Or,
should I go ahead and replace this 'switch'?

The mileage on the car is just shy of 84,000.

Thanks for the advice guys!

Gerri

Thanks. I've never seen any breakdown of the codes.

My '94 TB LX V8, I guarantee.

As I understand it, the other 94 TB tranny is AODE, which
has (old style) hydraulic downshift.

Safe to assume that all 94 TB 3.8's were mated to AODE?

Safe to assume that all AODE's had same MLPS as 4r70w?

I notice the TR codes don't have anything for, say,
supercharged V6 and manual tranny ...

Respectfully inquiring:
So, if Gerri's is "TR - LCCMM" and mine is "TR  L33FF",
how do we make sense of your code table (for trannies)?

 Thanks,

     How To Tell How Your Car is Equipped

     There is a small metal tag that is mounted inside of the
front-passenger door.  This tag, known as a Vehicle Certification
Label,
contains a lot of information about how your car is built and
equipped.
Diagram 1 below shows what a typical VCL for a 93-97 PI might look
like.

     There are several code fields on a VCL.  It makes it easier to
remember that there are codes that are above and below the horizontal
dividing line.  The two character code on the left side of the tag,
and
above the dividing line, designates the body paint color code.  The
codes on
the right side, and above the dividing line, are District codes that
designate where the car was built, and special order codes.

     The codes below the dividing line, from left to right, are as
follows:

     BODY = Body Type
     MLDG = Moulding Color/Type
     INT TRIM = Interior Trim (Seat Type/Color)
     Tape = Tape Trim Type
     R = Radio Type
     S = Sun Roof or Roof Sliding Panels Type (N/A on a PI)
     AX = Axle Type (Ratio and locked/unlocked)
     TR = Transmission type and suspension spring type

     The following are the known (at least by me) codes for each of
these
fields:

     Body Color:

     DZ = Light Saddle
     FG = Medium Berry Metallic
     FL = Toreador Red
     HB = Ivory
     LD = Medium Wedgewood Blue
     SL = Light Willow Metallic
     SH = Medium Willow Metallic
     TS = Silver Frost
     TR = Medium Graphite
     UA = Ebony Black
     WT = Performance While

     Body Code:

     FC = Police Interceptor (P71)
     BA4 = P72 Fleet Car or P73 Basic CV
     LX4 = LX Model CV

     Moulding:  Should always be CC for color coded to exterior paint
color.

     Interior Trim (First Part = Seat Type):

     K or M= Cloth K-Split Bench
     C = Leather K-Split Bench
     E = Vinyl K-Split Bench
     H = Cloth Bucket
     I = Cloth/Vinyl Bucket

     Interior Trim (Second Part = Interior Color):

     C = Currant
     N = Cordovan
     G = Willow
     L = Willow and Ivory
     P = Portofino
     S = Saddle
     X = Oxford White and Light Graphite
     2 = Light Graphite
     M = Portofino and Light Graphite

     Tape Trim Type: N/A

     Radio Type:

     6 = AM/FM/MPX, Electronic Premium Cassette
     F = AM/FM Stereo, Electronic
     H = AM/FM Stereo/Cassette, Electronic
     L = Luxury Radio AM/FM Stereo/Cassette
     2 = Radio Delete

     Sun Roof/Sliding Panel Codes (N/A on a PI):

     B = Sliding
     C = Removeable

     Axle Ratio:

     8 = 2.73:1
     Z = 3.08:1
     5 = 3.27:1 (Unlocked)
     E = 3.27:1 (Locked)

     Transmission Type:

     U = Automatic Overdrive, 4R70W (Standard on all CVs)
     X = Automatic Overdrive 4-Speed, AX4N

     Suspension Spring Type (This is a four character code.  The
letters
represent, in order, left-front, right-front, left-rear, and
right-rear):

     Front Spring Codes (Part Number and Catch Word):

     2 = F4AC-AA/AFD
     3 = F4AC-BA/BOS
     4 = F4AC-CA/CKV
     5 = F4AC-DA/DHL
     6 = F4AC-EA/ETR
     7 = F4AC-FA/FPK
     N = F4AC-ANA/NUL

     Rear Spring Codes (Part Number and Catch Word):

     E = D9AC-AEA/TOW
     J = F4AC-AA/ARP
     K = F4AC-BA/BKM
     L = F4AC-CA/CWT
     X = DZAB-DA/HDS
     Z = DZAB-CA/AIR
     C = F6AC-C/CMG
     D = F6AC-D/DSJ
