Zf5 mushy shifting

Seems like my shifter went from tight and precise to loose, sloppy, and mushy overnight.

Noy sure why. I checked to see if the shifter housing is loose and it's nice and tight.

Anyone have any insight?

Thanks.

Re: Zf5 mushy shifting

The only thing I can think of is the little white rectangular bushings under the top cover of the shifter. Here are part numbers for the bushings if that's the problem:

Shifter Bushings, ZF 5-Speed
ZF Part #: 1307 306 154
Ford Part #: E7TZ-7C371-A

Re: Zf5 mushy shifting

i guess more investigating this weekend....

i just don't understand how this happens overnight...literally.

either way...something isn't right. even looking at a replacement trans already...mines already making all kinds of grumbling noises...

Re: Zf5 mushy shifting

If every gear is being mushy all of the sudden it's in the shift lever housing. Pull it and check the detent.

Re: Zf5 mushy shifting

It's in the shifter housing...If you take off the top cover of the trans you issue is in that...You're shifter pivot and detent are on that.

Re: Zf5 mushy shifting

ok. hopefully there's something obvious in there... :-).

when i took it off to change the clutch, there didn't seem to be much to it all.
