Manual Transmission Removal
I want to remove the transmission from my 1955 Thunderbird to change the clutch, replace some seals and clean things up under there. The car is a manual three speed with O/D. Will I need to pull back the carpet to get to the shifter linkage? Can I disconnect the shifter arms from the transmission and leave the shifter itself bolted in the car? I understand the transmission cross member is removable in a 55. Anything I should be aware of before I do this?

Re: Manual Transmission Removal
In order to remove the transmission without partially disassembling it and partially assembling it during instal, it MUST come out the top with the engine. Easiest to leave it attached to the emgine and pull it as an assembly.

Re: Manual Transmission Removal
Too unwieldy. I prefer to take the trans out the bottom and the engine out the top. It's been many years since I did this on a small TBird. Does the shifter have to come out of the car to remove the transmission?

Re: Manual Transmission Removal
The instructions are in the 1957 Shop Manual and I would assume they are in the 1955 Shop Manual also. The short answer to your question is that you don't need to remove the shift linkage, just disconnect it from the transmission. The engine does not need to be removed either.

Re: Manual Transmission Removal
Thank you. That's the answer I was looking for. I didn't know if the stock manual trans shifter mechanism was like a Hurst shifter and had to be unbolted.
Re: Manual Transmission Removal
Is it the same for the 56 as far as not having to remove the motor to get the 3spd tranny out.

Re: Manual Transmission Removal
I am posting this reply for the benefit of other 1955 Thunderbird owners. To remove a stock overdrive three speed manual transmission from a 1955 Thunderbird, you should remove the engine. If you don't you will not be able to move the transmission far enough back for the input shaft to clear the bellhousing. The problem is the governor and O/D solenoid hit the X frame and the transmission tunnel is very small in a 55 Bird. The shifter mechanism also interferes. You could remove the radiator and move the engine forward. The shop manual says to remove the clutch, pressure plate and bellhousing with the transmission. On these cars, I think it's just as easy to take the engine out. Reinstall the engine and transmission as a unit. I suspect you could remove a non O/D three speed, but it would still be a hassle.
Re: Manual Transmission Removal
Interesting thread.
What is the consensus on removing a 3spd with OD in a 57?

Re: Manual Transmission Removal
I have been told the 57 Bird has a welded in transmission cross member. My 55 transmission cross member is bolted in and removable. If this is true, a 57 with O/D would be worse. A 57 Bird with O/D would also have a heavy duty T85 transmission which is much larger than my T86. However, the 57 tunnel is larger to compensate. Either way, I think it would be better to remove the engine from the car or at least lift it and move it forward. It's really tight under there.
Re: Manual Transmission Removal
Thanks Phil, it looks like I need to put it on the hoist and do some investigation of my oil leaks. Will read the manual as well I guess.
