what would make a c-4 feel like it dont/wont shift? Example when i drive 1 st feels like 3rd and when i put it in 2nd it feel like the car wants to die kinda like a break is being put on in the trans. Car wont shift other then reverse and 3rd which is 1st,2nd and 3rd. Im thinking pump went out or clutches are toast.:shakehead

hmmm wow I had the same thing happen to me this weekend in joliet with the same redneck c4.... dropped the pan on mine today,fluid isnt burnt,but it is full of metal.when I put mine in the first gear position it goes in and the brake holds but when you take off it feels like its in 2nd,shift it 1-2 nothing happens,2-3 shift is ok.I got no clue will be pulling it out this week,will probably be putting a glide back in though......

Sprayed I posted else where another guy called and said his red neck trans did the same as well. Interesting. I have owned mine a few years and maybe have 300 miles on it. But I have been deployed 3 out of the last 6 years. Actually it probally has mostly 1/8th mile and 1/4 mile passes. Anyone have a idea. I looked at the fluid, it didnt seem burnt,!

make sure the shifter adjustment is not out of wack. I had a cable go bad (split), got too close to an exhaust pipe somewhere down the line. Replaced it and all is well, don't have a redneck C4 though, just their converter and brake. drop the pan and see what you find. You could get a high pressure gauge and see what kind of pressure is in the tranny. Theres a port just in front and down from the shift arm.

Well they must of hired a some help! Or the sky is falling! Nope I think they have my number blocked. After they screwed up 4 times trying to get my stall correct maybe im blocked. But thanks sprayed347 for looking out! If the band let go before 500 miles must be a issue or this transmission is just weak. I had nothing really bad to say about them but this is getting rediculous fixing this trans. Pump shaft broke once,4 stalls and no this! Guess I will leave a message tomorrow. Thanks again sprayed347!

Sounds like a valve body problem. I know in my dealings with C4s or C6s over the years, the valve body is usually the culprit of most transmission problems.

Are you using a t-brake? If not, then it still most likely has the governor in the rear which is another problem area. I went to a full manual valve body t-brake a few years ago. Part of the installation process involved removing the governor permantely.

My suggestion is to go with a full manual valve body. Ever since I did that, I haven't had not even a single problem since.

yea they come with full manual valve bodys with a brake.took it apart too still found nothing wrong..reassembled and air checked ok.
Did you take the valve body itself apart? I had a valve stuck in mine once and it had no 2nd gear. 1st worked, 2nd was like neutral, 3rd worked. Also, if yours still has the governor, check that.

All the drums and servo pistons can still work when you apply air to them but won't work when the valve body is bolted up. Sometimes all it takes is one tiny bit of metal to stick a valve.

there is no governor,all valves are blocked off basicly except for the manual valve,took it all apart and cleaned...no problem found.possibly a servo problem,but who knows iam very close to just putting a glide in it and being done.thanks for the help iam at a loss.

Honestly my local built C-4 still works great! I bought it from a guy who had a shop put some parts in it, ran perfect. This tranny i have has worked fine all the way up to this year. But like I said there are hardly any miles on this trans. I dont make more 500 hp at the fly so this trans should not fall apart.

Nutzz, check your band adjustment. It may not be shot, just worn off enough friction material that it needs tightened up, also had that happen to me. Could be a possible servo problem, split or bad O-ring. Both are easy fixes.
