I've had my 92 Bonnevile SE for 3 months, got it at 186K miles now has 199k. In the last few weeks the check engine light has come on and off while driving. I replaced plugs/ wires, air filter, oil change trans fluid & filter change within last month. The major problem I'm having is when i start the car and put it in OD. it goes nowhere, drop it to 1 and it will slowly go until I can get to 15-20mph, once it gets to 2nd it'* fine, the car has trouble at low speeds in 1st gear, and reverse only. It will act up for a whole day, and then be fine on a trip, and start again on the way back. Today I started to rev engine to 2k rpm and drop it to 1 and it went without a problem. I also checked the codes with a paperclip and got codes, 26 (Quad Driver Fault), 41 (Cam Sensor Circuit), and 65 (Cruise Servo Position Sensor) .. Cruise has never worked since I've had it. What should I start on to fix it?

First off, driving it a year'* worth of miles, 13,000 in 3 months seems just a tad excessive for a car that old. Make sure it is well maintained or you should expect problems to increase.
I stopped my code 26 by cleaning the electrical connector for the purge solenoid on top of the charcoal canister. Yours may be related to your transmission problems. Look for anything that is obviously disconnected or broken like broken wires or unplugged sensor. Take apart the weather pack connectors for the cam sensor circuit and make sure they are clean and getting a good connection.
As far as the transmission itself, if it hasn't had the fluid changed recently, you should plan on doing that a couple of times. And you should never rev the engine before you drop it into gear. That is called a "neutral slam" and it is hard on equipment.

I replaced the Transmission Modulator, 11$ part and can now drive it without a"neutral slam" however it must be in 1, it will not accelerate in D,2, or OD. i checked all connectors and check engine light comes and goes while driving. i got a new code when i checked it last, 24. Any ideas or thoughts would be helpful thanks.

if i put it in D it will not go any where. its like as if it was in neutral. in order for it to start moving i have to put in 1st and as soon as its going about 5mph i switch it back to D and its fine from there untill i stop or go at a very low speed " about 5mph or so". it goes back to the bigginig "newtral". i have to start the hole process again.
if in d or 1 or anything and i push the accelator to much it makes a sound like skipping the links "krick, crick,crick. or i am pulling something. its like it does not grab the gears. any sugestions?
