so i put my new trans in yesterday and drove it around and everything is fine shifts great . so i took the car out tonight and everything is great . then the car starts acting weird the converter wont lock around 50 like it always does so i pull over to check th fuild it fine . i sit there for a alittle bit then i start my way home . it shifts 1st to 2nd then when it should shift into 3rd it just starts reving up . remind you i put about 50 since i put the trans in . any thing else you need to know just ask

any ideas

 

Most probably the fluid level; the dip stick is very hard to read accurately.

 

wouldnt it do slip in all the gears not just drive . it shifts into 2nd fine and it shifts into 3rd but it slips really bad

 

"New trans."? Whoever built it probably got something wrong in the 3-4 clutches. Take it back to them and have them check it. A 1-2-nuetral shift is usually a sure sign of a 3-4 clutch problem

no its not a new transmission i got it from a guys in pa . would you have to rebulid the whole thing of could you just put new cluths in it . it a full race rebulid in the trans now . he said it onle had 2000 miles on it .


thanks
jason

 

id go through the whole trans, 1 mans full race trans is another mans basic rebuild, id start from scratch and go through everything

 

i dont thinks its a basic rebulid i shifted fast then the one i just had in the car and that was a race rebulid

 

Now you're out the money that you paid for the used trans., and you still have to pay for a rebuild I remember you getting prices from me on EFA about your transmission. That price looks alot better now that you have to add up all the cost and aggrivation that you're in now.

As for, "Can you just replace the clutches"? Yea, it's possible to give you back 3rd and 4th...but...how long do you want them? A race 4L60E isn't a normal "animal". Most builders will always have a problem with them eating up 3-4 clutches...Just because most don't know what they're supposed to do to make one live. I get transmissions in my shop continually that have built at other places many many times with a "race" rebuild. Most peoples idea of a "race" rebuild is a stock transmission with a "Trans-Stop" shift it in it. This theory simply won't work with a 60E.

I hate to see anyone get beat out of money. I've tried to explain too many times about racing 4L60E's to people on here. A 60E can be built to hold up to extreme racing conditions IF it's built right. Unfortunately, there's only a handful of us in the country who are capable of building them right. I'll bet you a $100 that if you brought your transmission to me, I could show you exactly what they did wrong to cause the 3-4's to go, and I could show you that your transmission is nothing more than a stock transmission with a shift kit.
