Transmission Doesn't Shift
I drove the car upwards of 25 mph and there was no shift. The transmission was in D1. Fluid level is full.

My manual says the governor or valve body are likely responsible. Where do I start with this?

RE: Transmission Doesn't Shift
When you say "won't shift" do you mean won't shift out of low?
Mine does that. It's a linkage/strg clmn issue. I usually have to either have it hang up in low, or start in 2nd, then play with the shift lever to get it right. Start off in D2 and see if it goes 2nd-3rd as it should, then stop, start off in L, then slip it into D1 and see if it goes right. If not, then it could be internal.
Try the easy fix stuff 1st. All old Ford's, TBirds mostly, have very sloppy shft linkage.

RE: Transmission Doesn't Shift
I didn't think to try putting it in D2. I found neutral and then moved the shift lever through 2 distinct clicks, and assumed I was in D1. I do have a sloppy linkage. When I drove, it felt like I started in 1st gear and never left 1st gear.

I'll try what you mentioned ASAP.

It will be the weekend before I can check. To get a head start, if it doesn't do the 2-3 shift either, where should I start in addressing this problem? Preliminary searching has failed to turn up governors or valve bodies for sale.

RE: Transmission Doesn't Shift
I'm reasonably sure it's a linkage issue. I'm told there is a servo that can hang up in there. Just an adjustment, as are the (two) band adjustments. Try the D2 thing.

RE: Transmission Doesn't Shift
I was also told lack of use isn't good either. Makes things stick. We gotta drive these cars !!! I (try) to make it a point to drive mine once (or twice) a month . . . Just to blow the cobwebs out. I took my 60 out a few days ago . . . ran her up to about 80 on the freeway. Got back, ran the top down then back up (good to use the conv top too-keep those parts moving)

Drive em !!!!

RE: Transmission Doesn't Shift
I really hope you're right, I'd love it if my linkage was my only problem.

As for sitting being bad, I'm convinced that sitting is the worst thing (short of being in a wreck) for cars in almost every respect. I don't know when the last time my car was driven, but I know it's been more than a year, because the guy that had it before me didn't do any work on it, and the engine was disassembled!

In fact, the only clue I have to when it was last driven is the registration sticker on the license plate from Georgia--and it expired in '94!! Hopefully it's seen some action since then, but I'm not sure....

RE: Transmission Doesn't Shift
I drove the car in D2 and couldn't discern any shifting. I could tell I was in 2nd, but there was no third.

I'm hoping all that's wrong is the governor is stuck from lack of use.

RE: Transmission Doesn't Shift
Has the fluid been changed? Also, have (both) bands been adjusted?
You probably do have something sticking. Check the vac line going to the modulator (all the way down) I know on some GM trannys, if the vac line leaks, it will not up-shift. Not sure on the Ford.

RE: Transmission Doesn't Shift
whooa, vacuum line? I don't think I have any vacuum lines attached to the transmission. Should I?

Also, I haven't done any band adjustments. What are they?

Edit: I found this quote on the forum, elsewhere: "FORD changed the design of the CRUISE-O-MATIC in 1961 (first offered 1958) and included a modulator valve to control shifts rather than the throttle linkage used on the earlier COM/FOM."

If my throtle linkage wasn't adjusted properly, could that explain the lack of shifting?
