[QUOTE=rod7515]Brian, I see you have the BTO level 2, 2004r. What are your thoughts about it. What converter are you using. I purchased the same trans from them. I also have the 2800 Converter. My gears will be the 3:55 which are the same as you have? What RPMS are you running on the highway at different speeds? I plan on driving mine quite a bit and will be using it at 65 -70 on the highway. I checked out your home page and the car looks great. You've done a ton of upgrades. I didnt notice is you are running headers or stock manifolds? Hope to catch up with you some time.

I love it. I have the 2200 stall convertor. I run about 2300rpm's at 70mph Stock manifolds with the Magnaflow exhaust. I don't see headers doing much for me because I don't race. The added heat and cleance issue are not worth the small gains headers will give my setup. I added the B&M trans controller so the convertor does not lock-up unless I am going over 40mph and unlocks when I slow down under 38mph. I use to have a toggle switch but now it is totally hands free.

Brian, did you have to order that for your year or just purchased the ones that are listed for the 91 -92 vehicles that the link took me too? Just wondering why you dont pull it down into drive when you dont want to be in overdrive because of low speeds. Does that become a pain? Just wondering why. Looking forward to your comments. This will be new for me.
Thanks
Rodney

I ordered the one in the link. By adding the controller it works just like the rest of my cars with overdrive. I do not have to downshift them so why should I have to with the Vette. The worst case was highway driving. Every time I came to slow traffic or used an off-ramp I would slow down and have to downshift to keep the motor from chugging/pinging.
I found that to be a little combersome at times.
I guess if I had a manual trans I would have been downshifting but I should not have to with an auto trans.

Brain, Thanks for all your input. I will hopefully be driving this car in town often so I think you have a great point. I will probably order one of them. Was it tough to install or is it fairly simple. How does it monitor your speed to know when to shift?
Thanks
Rodney

It attaches to the speedo cable at the trans. Then you power the controller with 12 VDC when the key is on and a have good ground. The contorller has an adjustable switch so you set what speed you want the convertor to luckup at. The output connects to the power wire going to the trans at the brake switch so the trans does not get the 12 VDC unless you are at speed and of course you foot is not on the brake.

I am starting to have problems with my 71 Turbo 400, I am considering a 700R4 rather than overhauling the Turbo 400.  Is there any documentation that shows that this mod can be done to a 1971.

You can install an overdrive trans in ANY year Shark car. They are pretty much all the same underneath. Some years are easier than others, due to the exhaust pass-thru locations in the crossmember, but the install is pretty much the same for any of the year models.
