Time for a rebuild

 

It really is chicken and egg. You can drive youself nuts trying to figure out what went wrong with a given transmission. In the end is does not matter. All roads lead to a rebuild. Once you have tried to drive a car that is slipping you overheated and glazed the clutchs. Even if you found a external problem the remaining life of the trans would be measured in hours. Heck the overheated seals could blow out the second you fixed the problem.

 

Eep. That sounds like my old trans. Would hit the rev limiter if I tried to floor it in about 2nd gear going into 3rd. During normal driving it would shift great. After I got it home after I bought it, checked the trans fluid and it was low and leaking from the pan.

 

Awwww, this thread makes me sad, How much for a rebuild and shift kit?
Tranny can be removed taken apart and fixed at home unless machining has to be done

 

No machining on a Auto rebuild. The is a lot of special tools involved. There is also a lot of knowledge that goes along with it. For a normal person about 10 weeks of training about 2K worth of tools (in addition to you standard mechaincs tools) and you will be decent at a given tranny after about the 4th or 5th rebuild.

If it possible you could read thru GMs step by step manual, yes but then you would need every GM tool. Your not going to save money by doing one tranny. If you want to learn and add to your abilities then go for it. If you want to save money and have a dependable tranny find someone that knows the tranny like the back of his hand and see if he does side jobs. You pull the tranny and take it too him.

Shift kits have changed a lot, there is not much too them since the Tune on the PCM controls the shift. I think what you are looking for is hvy accumulator spings.

 

Look into a built-transmission, see

Well my grandfather is very familiar with Chevy transmissions and all worked on countless 700r4s and a few 4ls i believe, he is also good friends with Danny Blankenship who im sure could lend a hand. And as far as tools im sure his 1 acre shop has at least two of every kind known to man (Not trying to sound pretentious but if it can be done by man, he can do it)

 

i dont think the op has a relitive to do his work. performabuilt does good work and is a site sponsor
4l60e 700r4 4l80e performance gm ford transmission performabuilt

this is who i used and has kits, are also good with transmissions. not core here.
700R4 Performance Transmission from PATC, 700 Raptor 700R4

 

Wait, if i just get a new auto... can i get new gears?
like a longer first and a torque converter that will lock all the time instead of when convenient?
