Driving along stopped at a light then took off ended up at about 75% throttle and when it shifted to second I heard and felt a loud bang. Now I have no overdrive and my First to Second shift is wacked out. What did I do? And I would really like to have a 5 or 6 speed but I tow things once in awhile what would i need to swap in and what would it take? I have a tranny shop in town that is known to build some stout 4l60e's but I really want a stick.
Sorry bout the title. :)
T56 6 speed! nah thats more for racing... , is it slipping when shifting? still have 3rd?
I was told it could be a stripped sunshell. But yes i have 3rd and it slips going into second alittle bit.
yep, gota pull it and tear her down...., gona need a new gear band for sure and "the beast" .... you might as well go ahead and upgrade everything now...youll thank yourself later. i know that sometimes you can only do what your wallet allows but i'd hate to hear it happening again because you didnt beef it up. thats what i did with mine when my radiator blew went ahead and upgraded as much as i could afford. which of course with these trannys the best upgrade that is affordable is a 4L80e
So would I be best going with a FLT level 3 4l60 or a stock 4l80? I dont plan to make over 500hp this is going to be just a fun street truck. I will not be making that much power anytime soon either so idk.
on average, from my knowledge of the 4L80e, which is limited even though i rebuilt the one in my 2500, with a few slight mods it will hold 500 hp easy. but i've heard good things about FLT too. I'd give them a call and talk to Andy. I've PM'd him with a few questions and he was always helpful.
I just got off the phone with him. Gonna go with them thanks might end up with a level 4
Do you still have reverse? If so, it isn't the sunshell.
No reverse....
How many miles on your trans?
Probably what it is then. No reverse and it shifts straight from 1st to 3rd and no 4th. Same thing happened to mine, I went in and replaced the sunshell and gear.
it has anywhere from 60,000 to 100,000miles on it dont have the paper work and cant remember anymore.
Is it ok to drive it for awhile if its the sunshell?
I wouldn't. You risk damaging more parts.
Well i'm getting a FLT trans and a tru cool cooler and a Trailblazer converter what do i need for install? I have like 10 quarts of fluid in my garage.
youll need more than 10 for a fresh tranny, plus im sure the verter will be empty too so youll need around 13. may end up only using 12 i cant remember how much i put in mine when i did it. i know my 4L80e was 14
and MAKE SURE the verter is pushed onto the pump ALL the way. or youll be buying a new pump and verter..... had a buddy that did that. all youll really need is hand tools to install it, 15 mm wrenche for the bellhousing bolts, um i think 11mm for the driveshaft bolts to pull it. i believe the crossmember is a 15 too, not 100% sure. and make sure all your sensors are plugged back up. and DONT BRAKE YOUR LINKAGE CABLE. they are a lovely $150 something bucks... but its not hard to install one, i usually pull/ install one in around a hour and a half doing it on concrete with no lift, lift= time saver!
Alright sounds good doesn't sound like i need to much. Is valvoline fluid decent?
my 60e made a loud bang at SAR when hittin 2nd. i just lots 2nd all together that day. i drove it 700 miles home broke as hell, and made some runs at home with no 2nd, i drove it for a month like that. then one day it lost 3rd.Quote:

i wasnt saying a 4L60e cant be built to hold it, it can. its just cheaper to swap to a 4L80e because they are still a factory trans and with very few mods hold the power all day long and stand up to it which a properly built 4L60 could too. just costs more. and yes valvoline works.
takin the trans out today just started got the driveshft and y-pipe out. any need to knows?
