Ok guys, been doing a lot of work on my 92 RS now that I have A/C out in the garage ( a must in Houston Texas). So far I've done, coil relocation, put new freeze plugs in the back of the block (some of you might have read my post about pulling the tranny), changed tranny fluid + filter, new fuel filter, and I just finished up J B welding a hair line crack on the end of my radiator (you know those plastic ends). Also dicked around messing with that pipe that goes in below the intake, that was a b*tch because the old fitting broke clean off.

My "LAST DUMB PROBLEM" is I get a late and hard shift from 1 - 2 so I looked in the factory manual, says TV cable, well I've done the TV Cable adjustment lots of times but it doesn't change. It's weird because if you drive then stop at a store and start back up and drive again it goes away, like as if temp. has something to do with it. Any IDEAS???

The last thing that I finished up was you all know that plug next to the temp sensor, well I had a fan switch custom made for $25 bucks that comes on at 195 F, I took out that plug and YES it is a water plug (I think it's for FWD cars, where they put the dash heat sensor in, ours is on the head). Wired it up to the fan relay ground and it works real nice, all automatic and I left the computer control hooked up so that my A/C can turn on the fan too.

Thanks guys
Ryan

I don't know what the problem could be or if there even is one. My 83 is slow to take off and get going after it sits for a while. After I've been on the road a while it seems to shift and take off fine. However I have a carb and a 3spd rather than fuel injection and overdrive.

The trans might be on its way out, especially if the previous owner never changed the trans fluid. What year is your car again?

FAST RS

If the previous owner never changed the fluid its not good to change the fluid mine was never changed i changed it blew my tranny a week later. Ive known allot of people who never changed there tranny fluid and then they finaly change it and there tranny died.

KED85

THAT IS CORRECT
YET, regular maintenance calls for an annual change.
I changed my fluid after never changing it & well the tranny was always bad for the past 8 years, so, WTF.
Davids' point is very correct, tho.
Accept you'll be getting a rebuild tranny soon.....

FAST RS

Since we are on the tranny topic sorta Is it bad to switch fluids on the tranny lets say you were youing valvoline then go to B&M or mobil. Or is it best to stick with whats been in the tranny for a while

Ryan_Alswede

No that is not the case here, I brought my Camaro with 48,000 miles on it from a guy 1 mile from my house. I changed the fluid / filiter and did the whole flush thing a long time ago. The car now has 85,000 and the fluid just got changed again after I put in my rear block freeze plugs. It's just in the last 10,000 miles I get this high hard shift between 1-2. All other gears perfect no matter what temperture. I think it's one of three things:

TV Cable is binding somewhere
Engine isn't picking up the load after the shift
TV plunger is sticky

And if the car is hot it's fine, I'm thinking that the O2 sensor isn't sending the right fuel reading becuase it isn't hot enough so the engine is dies kind of during the shift. Thats why I was asking a while back about the life of one and I think what coats them is silicon (by product of combustion). And GM says replace every 30,000 miles.

When it's cold, and you keep engine speed below 2,000 it will fall right into 2nd ok but anything above that, get ready to lunge forward.

Also remember this transmission has NEVER been abused and it is the 4L60 tranny (i think it came out in 1990) which accourding to the guys on the tranny board they say it is way better then the 700 r4 because the 4L60 has a better lube pump and more splines on the converter drive shaft and other improvements. They used it in later Camaros only with an electronic valve body for control of shifts.

TomP

Well, the 4L60 is exactly a 700r4. GM changed the naming convention of their automatic transmissions. 4L60 = 4 speed, Longitudinally mounted, "60" is the torque rating. 4L80 = handles more power. 4T60 = Transverse mounted. I believe the only increase in spline count on the 3rd gen 700r4/4L60's/whatever you want to call them happened in '85.

GM changed their 700r4's through the years ('85 is better than 82-83, '87 is better than 85-86, etc), so your '90 might've gotten a better fluid pump. That was one of the biggest changes in '87, an improved fluid pump, with unevenly spaced vanes that prevented aeration of the fluid.

I hope it's not the tranny! What shape was the fluid in when you did the first fluid change?

Ryan_Alswede

The fluid was fine when I had them do the flush. All they do in a flush is pump new fluid into the tranny until it comes out clean. There has never been any metal in the pan. By the way my Camaro is a 1992.

No it's not the tranny going, no way.

Thank guys
Ryan

Whenever I adjust my TV cable on my '84...First off when I do the adjustment like the manual says make sure that the floor mat isn't under the gas pedal, the pedal needs to go as far as it can go...I then take the car for a ride and usually still have to do some fine adjusting. I do this by marking the position of the piece that you have to push back for the intial adjustment and then depress the tab like orginally and pull the piece ahead just a little bit. Take the car for a drive and if need so readjust.

The problem was timming! So if anybody does a search the answer was timming!

Cool, thanks for the update, Ryan!
