I have a '76 Bronco 302 with a C4. I am replacing modulator valve on transmission and the Ford dealer has 3 color codes listed. He says I must match up color to the old one to get correct replacement. Of course after 30 years there is no color left on the old one. Autozone lists black stripe type which doesn't work properly.
Does anyone know correct color code for this Bronco.
I tried the black stripe from Autozone and the shifting was not normal. Much higher rpms to shift from 1st to 2nd and slightest touch of accelerator would cause downshift from 3rd to 2nd. at all speeds.
Called several parts stores, another Ford dealer, and finally a transmission shop and got different answers from all of them. Trans tech said black stripe is for diesels and heavy duty use. I have most faith in him - he said to get a green stripe but I thought I would check to be sure.
Rock Auto lists about 5 different colors all for 76 Bronco.
