hi, I live in Scotland and we don't have many transmission specialists.

I have a 1956 Ford F100 with a 1970s C4.

It started leaking very badly, so I opened it up and replaced a couple of the front seals -the one on the shaft, and the one around the oil pump. I did not open the value body, nor touch anything else.

Knowing nothing about transmissions, I was hoping to get off with this and everything would work fine...

Needless to say, the oil leak is fixed.

BUT it wants to drive in all positions of the selector --we have removed it and are now pulling/pushing manually, but same issue.

Feels like it is pulling in second gear.

I have not found any posts with a c4 driving forward in park!

Arrrggg. Any ideas?

unfortunately, to remove the trans, i have to take the whole engine out too, which was not fun, as I am sure yous well know.

Hi mate did you tighten up the band to hold the internals steady while pulling the pump out? Just thinkin something is binding and hold a gear. Otherwise it sounds like the forward clutch is stuck on?
Im not an expert but just thinking out loud. Wait for Greg or Paul etc to come on and see this they will probably know.

Hi tong, many thanks for the quick reply.

No, we didnt do anything sensible, we just pulled it open, replaced the gasket and shook it back together again...

(regretting that now)

Sounds like when you pulled the pump one of the thrust washers has come adrift and is now sqeezing something tight. Youll have to pull the pump and invetigate. Have a look through the monster thread or google image "c4 transmission" and you will see the diagram that shows the position of the parts. hth

You did line up the selector linkage with the valvebody internally as the valve body went back into position??? as well as the kickdown lever ?? Don't laugh someone here did that few weeks ago.

Mmm failing that as Tony suggested , I hope the thrust washer on the end of the stator support + the #1 washer on the back of the pump was stuck in position with assembly lube when the pump was refitted . Each washer has locating tangs and if not alligned with lock up the trans .. Was there endfloat after reassembly??

Did the pump drop back in easy?? Hoping also the high drum stayed put and didn't lift up when removing the pump and now the high/reverse clutches are misaligned :(

My thought parallels Greg's here. I believe you do not have the manual valve properly aligned with the rooster comb.
