Use your car's VIN number to order the latest pressure modulator. This will eliminate any questions.

Good luck

The one the dealer sells you after looking up your vin# in their system. That is the one designed for your specific car.

Using your VIN number to order with will get you the correct modulator for your car. Plain and simple...Forget all this color business.

The dealer will sell you the most current version of the modulator for your car.

I will go ahead and order now

many thanks for all replies

@MAYFAIR, if you're still planning on doing the ATF oil and filter swap then Mobil D/M might be a cheaper alternative. I've found it here in the states for ~$18 per case of 6:


but I don't know if you will get killed with shipping. Maybe a local UK supplier has the same for a decent price.

hi

at this stage going to try just replacing the regulator as if that works i will leave filter and fluid alone -as previous posts suggest it may enhance the harsh shifts -we will see once modulator fitted and go from there

Your inconsistent shifts have me wondering if your problem is with the vacuum line. Would be well worth it to replace every vacuum line that it shares vacuum with as they may look ok but leak.

It is true that cold trans fluid is thicker but because of the cold the trans pump is pumping less fluid than when it’s warm so it’s not clear cut.

If the car can shift ok under some conditions then I’d almost completely rule out the transmission itself & focus entirely on transmission shift control. If you know the fluid is of the right type, looks ok, and is at the right level after a full 20 min warmup then it’s unlikely to be causing intermittent shift issues as well.

Just my .02, worth what you paid

hi thanks for advice -- my plan is to turn down the modulator and if instant improvement - great ,at that point will replace the module -if stays the same will follow your advice and then replace the vac lines and joints with
a new set .
will report outcome soon either way

thanks for

hi

turned the modulator white plastic adjuster as far as would go anti clockwise and,,,,,,,,,,

smother shifts ,except on 2nd to third still had the clunk ,so i have no more adjustment anti clockwise

will now have the vacum pipe checked when i can borrow a vacum gun ,if thats ok will try a new modulator

*just an after thought would turning the lever clockwise a bit in various positions help ? or once its right round
anti clocwise is that the softest it can be ?

i am getting there bit by bit :)

Remember, a super soft shift will put much more wear on the clutch disk than a somewhat firm engagement.

^This X 100. Softer shifts comes are severely reduced transmission longevity.

You want quick & firm shift, not "smooth as butter" ones.
