Hello,
I'm looking at installing a manual valve body in my AOD (1990 model Fox). I have been considering the constant pressure unit from TCI. Anyone have an opinion on this unit or what do you suggest. I have been having problems with the first to drive back to second not shifting properly. Trans was rebuilt about 2000 miles ago. TV cable adjusted by a certified trans shop. Trans works very good otherwise.
thanks
Grandpa:confused:

I would not suggest the TCI CP unit to anyone, as I have modified many of them to make them "right". Internet search for reviews you will probably find more nay than yay for sure.

the CP unit is NOT a MVB however
a MVB is it’s own breed, no auto shift at all.
You need to make up your mind if you want to just ditch the 1d1 shuffle or go MVB
There are tons of MVB's but as for AUTO SHIFT units that hold manual 2nd there are three (which I explain bellow)
PA: simply the epoxy mod to a stock vb, otherwise add some drill holes, done. Anyone can epoxy and add a shift kit for under $100 to their own VB.
Lentech: Street Terminator, great vb, made and shipped from Canada - missing some finer notes to overall customer satisfaction and harsh 4-3 shift.
SPT: Ahem…custom calibration per customer, finer adjustments added, MADE IN USA

Your car must be a 4 cylinder conversion. The shift pattern you described is for the a4ld, the auto that went behind the 2.3 4 cylinder. The aod pattern is p r n od 3 1/2. To shift manually, you have to perform the "aod shuffle" of shifting to 3 and back to 1 in order to hold second gear

AODs can be great transmissions if built properly. 4r70w internals, single piece input shaft, and a silverfox or lentech mvb would be a strong little transmission. The solution to your shifting problems for the moment is to get the shifted out of a v8 car...see how you like it then
