What kind of tuning will I need when I install my 3600 / 1.8STR torque converter? i am not really talking about a shiftkit.. i know that'd help with the firmness of the shifts, and everything.. but i would like to see if i like how it feels without the shiftkit first.. and then if i feel i need it, i'll buy the transgo shiftkit.

but my question is more to the nature of "what do i need to do to ensure my tranny won't take a ****?" ... b&m 24,000gvw tranny cooler is going in with the TC, and i am also going to install a tranny temp gauge to monitor the tranny temp just in case ... but what else would i need, and how much will it cost?

I would consider replacing the stock flexplate with a TCI SF29 unit, you need to remove 3 of the 6 bolts of the flexplate to replace the TC, might as well get it then.

why? what's it do? seeing how my T/A is a 2000 and all posts i can find say 98, 99, and 2000 are fine.. its the 2001 and 2002 that have the POS flexplate ..

i dont really have $199 laying around doing nothing.. so if it should be fine, why replace it ?

i have an 02 car and didnt replace my flexplate. i have a yank 3600 as well, if you have a big cooler and guage you should be fine.

What exakly is wrong w/ the 02 flex plates?

SteveC

They went to a different flexplate in 01 & 02 that is more hogged out and thinner, it is prone to cracking.

My point:

You are installing a high stall (3600) with a smaller diameter TC, for $199 more, you can replace the flexplate WHILE YOU ARE ALREADY IN THERE, and end any FUTURE possible problems related to the higher stall, str, and rotating mass.

your trannie will **** as long as its a 4l60e... I've had mine at the track with about 20 passes on it with a 1.5x 60ft time and now its starting to do stupid ****... like not shift into 4th.... so ill be swapping in a th350 as soon as it goes up in smoke..... *damn 4l60e*

so no matter what i do, with a 3600 / 1.8STR stall my 4l60e is going to break?

yep, just give it some time

firechicken2k

now i'm not sure if i want to install my TC
don't really have $2,000 for FLP level 4 trans plus unknown amount of $ for the install..

firechicken2k

and i see you have a TC but i don't see a tranny in your mod list.. how long've you had your stall, what STR is it, and how's your tranny doing ?

Don't let them scare you. I know guys that had bolt-ons, 4000 stall and 24K cooler last a long, long time with the 4L60E. It is a crap tranny and will break eventually but it would do that with a stock torque converter too. All you need is the tranny cooler and you'll be fine. Heat is what kills transmissions quicker then anything. As long as you keep an eye on the temperature and aren't running over 400 rwhp your tranny has a chance to last a long time. Just save some cash as you go so when it does eventually break you got the money to replace it with a stronger one (built 4L60E or even better a TH400).

Good Luck

th400.. how would my highway driving be on that beauty?

heh.. ill try not to get scared too much.. although my goal *was* 450 rwhp, i guess ill lower it to 400rwhp until i got some money i can spend on a new tranny

thanks, man.. at least now i know ive a chance, somewhat, to not need a new tranny soon

darrensls1formula

Highway driving with a TH400 = high RPM's and bad gas mileage But there is a overdrive unit you can buy to get fourth gear back But it costs a lot of money. I forgot how much exactly but I wanna say it's about $2500 and that's just for the overdrive part not the tranny itself

Yeah it's hard to keep 4L60E's alive for more then a year at a time if you pushing between 400-500 RWHP. And anything above 500 forget it. A few guys have gotten 4L80E's here to work but it seems TH400 is the more popular route once power gets big.

a tranny wouldnt be in my mod list if it's a stock 4l60e would it? yes, I'm on tranny #2. 2.6 or 2.7 STR. ive only had it a couple thousand miles, but my other tranny wasnt acting right after racing it with my HPP3 for some years.

firechicken2k

what about flp level 4? its a built 4l60e, so you still have overdrive.. its $1,999 (so cheaper than th400 + overdrive) .. wouldn't that be good enough for ~450rwhp (my original goal) ?

and from what i understand, it'll act just like the stock 4l60e.... just wouldnt break or am i wrong?

302-250-1202 just tell frank what you want . it will last a long time or he will fix it free. Best dam tranny guy in the country on 4l60e was running 580 rwhp on a 408 for 30,000 miles then sold the car still working perfect.

wow, thread revival of 2 years. yea, I'll vouch for Frank. I'm running his trans now. you may want to remove his info since he is not a sponsor.
