Re: Help me choose a tranny

Definately a square pan. No modulator. I have a TH350 from the other truck sitting right next to it. I had never heard of a 700R that wasn't an overdrive, but I am continually surprised by what I dont know. The guy that was going to do the tranny swap told me that they made a non-overdrive version.

I have spent too much time on bowtieoverdrives ( I don't know which is worse, the drool or the confusion). I have also spoken with Steve. That was before this question came up.

I was planning on ordering the TV cable from bowtieoverdrive, once I settled the carb install.

I feel the same way. I think I had to read the same thing about 10 times before I finally understood what it was trying to say for the swap. I still haven't done mine yet, but plan on it in the near future. I love my old truck, but a TH350 just doesn't do me any good when it comes to fuel mileage. I need an overdrive. And a turbo, come to think of it...

Re: Help me choose a tranny

I spoke with Steve at Bowtie. He verified that I got bad infomation. All 700R trannies have overdrive. However, he thought, based on my shifter setup, that the transmission I have may not be original to my truck. My shift indicator only has "D", "2" and "1". I should have "D", "D3" or "3", "2" and "1".

I need to figure out what I need to change on the column and the linkage to give me the correct shifting options.

Re: Help me choose a tranny

Well what do you know. I did have a overdrive shifter in my truck. In my defense, the indicator doesn't work, so I didn't look at it. But after my conversation with Steve today, I checked it when I got home.

So, I already have the right tranny, drive shaft, shifter and (since it was a six) a slightly higher stall on the torque converter. I think I will order the Level 2 rebuild kit from Bowtie and that will do it.
