Looking for a transmission kit

I posted a few months ago about some transmission problems I was having, and I will have some time in the next few weeks so I am going to try and rebuild it within that time. Im not looking to add any power I am just trying to get it running again. From what I've been reading and what you have said in previous posts, it appears I have burnt c1 and c2 clutches. It will shift into 1st, 2nd, 3rd (not great) but it will shift into them, and when it tries to shift into 4th it will try for a split second and then just go into limp mode.

I am thinking I just need to drop the transmission and replace the c1 and c2 clutches and maybe install a transgo shift kit. I was looking at the gmax5 kit on Suncoast's website.

I understand that it would be best to replace the torque converter as well but I dont think I will be able to afford a full kit anytime soon. So I am wondering, are torque converters usually effected if clutches burn up? Or do you think it is necessary to replace this as well?

If they are messed up, would you guys suggest just buying stock clutches and a stock torque converter? I am open to whatever, so if there are any other ideas I would appreciate it. I am a college student so that is the reason I am trying to get the best low budget kit to get it running again.

Thanks

Torque converters are affected, the crud from the clutch pack goes into the converter and kills it slowly. Also need to be sure to clean the cooler.

Many vendors here carry them, look them up towards the bottom of the site and start dialing or searching web sites.

I would imagine your C3 clutches are toast. C3s are what give out in 4th and 5th gear. Could be the C2s as they are engaged in 4th and 5th as well but from what I understand its the C3s that do the most slipping. A 225 hp tune with 37 inch tires is going to take a pretty serious rebuild.

For what its worth my C3s are weak. I've put it into limp mode twice and have made it slip in 5th a few times since but backed off as soon as I felt it slipping. I've driven it 10,000 miles since it first limped. My plans are pretty simple. The controversial but effective TTS C3 upgrade and transgo shift kit, new stock clutches and a 2011+ LML torque converter. I got the converter at cost but had to pay the core charge but still only set me back $550 for a dual disc heavy duty converter that I'm told can handle 1000 ft lbs of torque. I'm still looking at spending $1500 in parts but thats still fairly budgeted for an Allison.

Thanks everyone. I took everything apart and my C1 and C3's are toast. C4's seem to be a little worn out as well. So I ordered the alligator performance stage 5 kit with precision tc.

One question though, what is the best way to go about cleaning the transmission lines? Just take them apart and flush them? Do I need to take off the cooler as well and clean it too?
