Hi looking for opinions, advice on swapping out 2spd tranny in 65 gto to some other auto. I found the cable kit to use stock shifter but not sure witch trans to use. any information would b appricated. Thanks

A350 Turbo is the easiest, a direct bolt in if your car is a column shift. If you have a console, you can get linkage that will make it a bolt in.

GTO1 is correct, a TH350 short tail is the best way to go. I took the 300 out of my 64 when I restored it and put in a TH350 and glad I did. The 3 speed makes the car a lot more fun to drive. I put a shift kit in it and get my kicks chearping the tires from 1st to 2nd.

Shiftworks makes a great kit to convert a 2 speed selector over to a 3 speed yet allows you to keep the car looking like a 2 speed. You can go into my site and see a link to shiftworks website.

Good luck

Thanks sounds like th350 is the way to go.

i put a 400 in mine

[rotdog]

Any pros or cons on the 400 tranny? The car is not a hot rod just a fuuun driver.

[zbuickman]

ALOT stouter tranny with a higher torque rating.

[lil64gto]

If you go with a th400 you will need to modify the tranny mount and most likely alter the drive shaft.

[Old Man Taylor]

All you have to do with the T-400 is move the cross member back, the trans mount is OK. You will probably also have to shorten the drive shaft a small amount, but it is close.

Unless you are pulling serious hp and torque numbers and have a stout rear end and fat sticky tires, a built TH350 and decent converter will be all you need. It's a direct bolt in. I bought one for my '64 GTO from Jegs. I think it was about $950 which included $99 worth of shipping. It was one of the less expensive transmissions they had available.

[rotdog]

Hay thanks for advice i think ill go with the 350. Are car and pickup the same?I'm just kicking ideas. Gotta get front end totally rebuilt first. The 2spd still pulls great but got magor tail shaft play = VIBRATION. Thanks.

[sandmanjoe]

go with a 400, its not that hard to do, drill 4 holes move the cross back and use a drive shaft from the car you got the 400 from, chances are it will work great. unsure of all years that the shaft will work so take a tape measure with ya. but any good junk yard will have that shaft you need.

[sandmanjoe]

also make sure you get the trans from a v8,,,,v6 autos use less clutches.

[Old Man Taylor]

A bolt in is to use the drive shaft from a '67 GTO that came with a T-400.

I put a 2004r in my gto fit great bolt in except had to move rear mount back 3 in and re drill. It works great have 355 rear ,can use orig shifter with the shift works kit. You have the best of two worlds. Can run hot in drive then cruise when the converter locks up in over drive. Hope this helps

It's a little more work ,But I put a 700R4 in mine and can do the same as to what Donc said....I guess the choice is yours...

Went with th350. 3rd gear really helps. Thanks all

How does the THM 350 downshift when the gas pedal is floored?.........the ST 300 in my '64 uses a kick-down switch mounted on a bracket off the carb base

[rotdog]

Down shift cable to carb. i havent hooked mine up but its in place.
