hard shift into drive
I have a 86 camaro with a 89 l98 corvette engine and a 700r4. I just tightened the detent cable a little bit and now everytime i shift into drive the whole car jumps. The shifts are harder but feel normal. Is something wrong?

hard shifts
well im sorry i cant really help you, but i sure can impathize. i just rebuilt my car, and got a new tranny our of a salvage yard, and it really lurches when i put it in gear. but it is allso about impossible to drive mine without it getting 2nd gear scratch, not a real bad deal when i want to race, but let me tell ya what, cops sure as hell dont like it when they're behind ya.
allso a question for you. what exactly is the "detent cable" is that the kickdown cable.?

try this method of adjusting the cable,
GM 700R4 Throttle Valve Cable Adjustment
1. Remove air cleaner on vehicles with carb or TBI.
2. Depress lock tab down on TV cable and push cable all the way forward towards carb or injector.
3. Have someone sit in vehicle and depress gas pedal to the floor so it's at WOT (Wide Open Throttle). Hold it there for steps 4 and 5.
4. Now check to make sure the carb arm is bottomed out or has no more movement. If not, use a pair of Channel Locks to bend TV cable bracket until carb or injector arm no longer rotates.
5. Next, depress lock tap down and pull TV cable back (Pull HARD!) towards firewall or away from carb or injector until it stops and then release the tab.
6. Use a pocket knife or hacksaw blade to mark the cable in front of the snout. This is MAX TV.
7. After marking Max. TV depress lock tab and push cable forward toward carb or injector 1/8'' of an inch. Make a mark in front of snout. This is Minimum TV.
8. Set cable back to Max. TV and Road Test.
Road Test: Super Important
First thing to check on road test is for Detent. Here's how- Make a very light throttle or minimum throttle 1-2 upshift. As soon as it shifts, floor the throttle. The transmission MUST shift back to 1st gear. If it doesn't you need more T.V.
Note
Most Diesels and V8's will work best at Max. TV to 2 clicks away. 4 cyl and V6's will work best at 2 to 4 clicks away from Max.
