Fluids are all good also it had got to where I believe would be 3rd and wouldn go into 4th just when u let off the gas the rpm would go down to idling but when I got back on the gas it would rev up till it caught, there where no sounds when this happend, do u know what all trannys will bolt up with my car and would I have to change any wiring harnesses it has a stock 4L60e but ive also heard to put a 4L80e and its a monster, what is everyones opinion on this

I would take off the oilpan and look for dirt in the oilfilter to start with.
It might be full of it, and therefore not shifting.
My old tranny started the same way.

the oil pan ? or the trans fluid pan and filter ? oil and filter change was done a month ago, and is 400 mile till its due again, also does anyone know what all transmissions will bolt up with the ls1 and fit in the tunnel without having to cut it down, and if the tail housing needs to be changed, if i have to change trans i would like to know diff options

The oilpan and oilfilter on the transmission, yes... Not on the actual engine

ok ill try that its worth a shot, the tranny has 181k miles, people also keep telling me to check the shift solenoid in the bottom end of the tranny, im going to replace them while i have the pan dropped anyway, you dont have to drop the valve body do you ?
