Well last night was my first time racing...everything went pretty well except my transmission. I am running a TH350 in 2ng gear but under caution it shifts to 1st and wont shift back into 2nd until my RPMs are way too high....I have the vacume plugged and the cable unhooked...I thought it was just supposed to stay in 2nd like that. I didnt take the cable out, just tied it out of the way but I have the center part of the cable pulled out instead of pushed in, would that make it downshift under caution? What am I doing wrong here guys????

THANKS

Thats your kick down, the tranny thinks you are at wide open throttle if you have it pulled tight.

keep it the way you have it, but let the cable all the way in.

dont have the cable itself (you know the metal stuff inside the plastic sheething) pulled out....


Understand what Im trying to say?

I have a 350 turbo in my car also. I have it hooked up where the kickdown cable is capped off and the modulator valve is hooked up to the intake for vaccumn. I can manually shift it from first to second and back into first just like a standard tranny with no problems.

Ok, right now I have the metal part inside the plastic pulled out tight and tied. So I should push it in and then just wrap it out of the way again. Dont really want to drop the pan to unhook it because I have clean fluid and Lucas in there...

Is there any way I can leave the cable in but have it not effect the transmission shifting???

YES, push the cable back in, it does not need to be pulled tight.

That cable was originally hooked to your throttle. So when you give it full throttle, the cable would get pulled out, and it would mnake the tranny shift down a gear. Thats what your problem is, the transmission thinks you are at full throttle and is dropping a gear. If you let the cable back in, it will shift early into second and stay there until you are at **** near a dead stop, unless you down shift.

you don't have to drop the pan to unhook them!!! take the litle bolt out that holds the cable housing to the transmission then let slack in the cable and move it and it will come unhooked (sometimes if you can't get it to come unhooked pull it out and grab the metal rod with a pair of pliers then unhook it)

drive hard or drive home

Well, tried pushing the cable in and tieing it up out of the way, its still starting in 1st and I have to baby it around 6000 RPMs to get it to shift. Might have to try to get the cable out without dropping the pan, will this cure the problem for sure or what should I do to make it start in 2nd??? Any ideas would be great......
THANKS

Im not trying to shift at all because I actualy cant reach the shifter if its in 1st gear, I had always planned to leave it in 2nd, so that poses a problem if I have to shift from 1 to 2. I am going to have to figure something out because now its going to 6000 RPMs before I baby it and get it to shift into 2nd, then as soon as we have a caution or I slow down it downshifts into 1st again and I have to go through all that again.

Well, I removed my cable and extended my shifter so I can reach it in 1st gear, had to move gauges and stuff, so it wasnt easy. If the weather cooperates this weekend I'll try it out. Thanks for all the help guys.

BTW I run 3.73s

You need to remove the govenor cap and tack weld the govenor open or tie it open with a piece of wire or tie strap then the transmission will down shift only when you manually shift it.

There is a clip on the driver side rear of the transmission that holds a cap kinda like a master cylinder.Pop the clip back and remove the govenor cap and open the govenor wide open and tack weld it or tie it open.

Works every time.

think your governor is sticking and it takes 6000 to break it loose pull governor out clean it up and check it for binds or catches it should swing out smooth. leave your kick down cable all the way in. B&M makes a kit to make a automatic transmition a manual whatever gear it is in it will stay in you will need a shifter though starting in second gear is hard on a tranny.
