While driving merrily down the freeway at 65 mph I was greeted by the sound of a high pitched whirring and bang. After coming to a stop at the side of the road I figured out that my tranny had blown up. See exhibit A, a view from the front.

Note the gears hanging down in the middle center. I also have a picture of the piece that came flying off and the hole in the tranny up close:

So I rented a trailer and drove her back up to the San Francisco bay area. Now I have to figure out what I want to do to get her going again.

Suggestions anyone? The car is a '69 Convertible, 351W, and 3-speed manual with a newly added ventilation hole. I was looking to go for something along the lines of a 4 or 5 speed. Any thoughts on how hard it would be to put in a 4 speed toploader or a t-5? Costs?

Thanks in advance for all your help,

Dave.

A toploader is a bolt in affair - the only thing that may need changing out is the speedo cable and possibly the driveshaft. I have one in my convertible and it's a pretty decent transmission.

The T5 conversion is somewhat expensive but seems to draw raves from everyone on here who's done one. For you, without the luxury of already having a decent tranny to work with, it might be feasible, since a toploader that's been gone through will probably cost around $600 or so anyway.

Those are some vicious pictures! Never seen something like that on a transmission before..was there any leakage from the tranny in the days prior to this? I would think that there was a serious crack in the case for some time that just gradually worsened before that happened; possibly losing all your fluid and getting the gears so hot that they tore up and finished the job on the case....

Wow, You broke that real good. Since you have to get a trans I would definitely go the T5 route.

Impressive example of traumatic dissassembly !! I would stay with a toploader. The T-5 conversion requires clutch mods (cable system) and a special crossmember and possibly a custom driveshaft. Kits are available if you are hardover on the T-5 option.

Wow, your lucky the back wheels didn't lock up when it came apart like mine did, the first time.

If you go the T5 route, be cautious as to how you will be driving and how much power you plan on forcing through the transmission. I have a 351w in my 67, and I am on the edge of putting too much power through my T5, well, I have crossed that line once or twice, and ended up with a case full of broken gears to prove it. I was being rough with it, and I had a nasty case of wheel hop, went with a loud bang, very loud. But, if you treat it nicely and keep your tire smokin' 2 - 3 shifts to a minimum, it should last a long time.

Check my web site out, I have documented some stuff that I had to purchase to get the T5 in and working. You are lucky cause you already have the stick shift stuff in it, I went from a C4 to a T5. If you have any specific questions just ask.

Been there done that. I now have a Tremec. I would skip over the T5 and get a Tremec as well. Just my 2cents. I feel for you.
