    I have a pan fill c-4 in my Maverick. I have the stock column,rebuilt good and tight,but when I shift from Park into the gears I get reverse from R all the way to N... Drive is in 2nd,and 2nd is in low,and I cant seem to get low ever... Any adjustment messes everything up. If I have a good solid Park,then I have to slam it in low,and maybe it'll catch drive,maybe not,or it'll pop into N... If I adjust it to get drive in D,still no low,and park is rewind... Is there something different about the trans shift arm that is that much different in a Mav/Cumit? This car was received in parts,loosely assembled,and I'm trying to figure out this stupid linkage issue,so if I park it it don't run away,until I can get the parking brake fixed... I've looked at some other fords,and they all seem to be similar when it comes to linkages... I plan on an AOD swap at some point,but till the C-4 gives up I plan on driving it... Thanks,Skip...

    I would check the plastic bushings on the shifter linkage.

    Thanks,yeah replaced them all when I done the column,it was all apart,didn't want it to be sloppy... I can only wonder if its a length issue with the trans arm making it not have the correct range of motion... Anybody have a pic of a stock Mav linkage setup...

    A arm that is too long or maybe angled incorrectly would cause your issue...

    What size motor? The linkage is different based on the motor.

    It's a 302... Have no idea what vehicle the trans came out of... Being a pan fill big bell housing,was most likely a truck van or big car... I'd get the correct trans shaft,but not sure what a mav shaft looks like... Thanks

    My guess.....based on your symptoms....is the linkage is the wrong one.

    Here is a picture of what V-8 linkage looks like on a Maverick

    The lever on my original case fill, column shift C4 is approx 2 1/8"...

    If you have a lever of probably more than 2 1/2" - 2 3/4", that's your problem...

    View attachment 115432 [/QUOTE] That's exactly what i have,welded up and re-drilled for snug fit,slop bothers me... :yup: Krazy Comet,I measured mine at nearly 2-3/4 from hole to kickdown shaft... Crap! pan's gotta come back off... A new seal wouldn't be bad idea... :slap:

    My measurement was from center of kickdown lever stud, to center of linkage where it attaches to arm... Bit of a angle, but it's definitely less than 2ΒΌ", shorter than I imagined... That big bell C4 is probably from a truck or van, maybe full size Ford... AFAIK no Maverick, Mustang, Falcon, Fairlane etc used those..

    Slop in the bushings is why Ford was sued and had to send out stickers saying to set parking brake... Loose linkage allowed the vibration of idling engine to shake the trans out of park & into reverse...

    One morning around 6:00 the paper girl's old F-100 jumped into reverse while she was running door to door delivering papers... BLAM!! It found the front of my work van parked in street...

    Yeah,I have a late 5.0 block so i made an adapter to replace the ball stud mount from angle with a 7/16 bolt welded through hole and cut off at shoulder,then longer bellhousing bolt and nut... Welded hole in linkage nearly shut,put in drill press and redrilled... New bushings in linkage,kickdown works,tight can feel all the detents in column... Just no low or park,if it's creeping will sometimes catch park,sometimes... Whats goofy is Reverse is pretty much R-N no matter where I adjust... Afraid to cut reweld for fear of igniting the seal:eek:... And a redrill means removing header collector bolts and front half exhaust system,or floor shift... Thanks

    floor shift and never worry about it again plus the cool factor of a floor shift
