Can you use a TH400 and use the stock shifter so the car looks stock??

Looking fopr a streetable trans yet capable of low 10s

 

yes...i am doing that ....just have to drill a hole in the stock cable bracket that bolts to the tranny pan

 

I see a lot of you guys are also running 350 tranny's. What is the major price difference in building a nice 350 compared to a nice 400? I know that the 350's are nice but I was just wanting to go with something that could be built for a decent price but hold anything I throw at it. I would be interested in a 350 if I could get one built for a decent price though, I just haven't done much research on them to know how much they cost.

 

check with Rossler, I just got mine and i must say it is a very nice piece. can't wait to get it in and see what she will do. i am going from a Bult 4l60e and a PY4000E to a Rossler TH350 with a T Brake and a 44-4600 stall. hoping to crack off a high 10 with a 36-3700# car with me in it. and then 9's on a 150 shot. but on the weight issue, it was explained to me as a Th350 and a 4l60E are from the same family, and a Th400 and a 4l80E are from the same family, so i would figure a Th350 is lightest, then 4l60E, Th400, 4l80E. just my opinion, not worth much but there ya go, lol

 

th400 is the only way to fly with a trans brake and reverse manual valvebody,let her rip

 

I had a 350 in my last car...didn't like it because it didn't have an overdrive

Otherwise good transmission.

 

Mountain, Rossler's 350's are generally a $100-200 more than the 400's. 400's can hold more power, but when your talking a 350 holding up to over 850hp/tq, what more do you plan on throwing at her?

 

Yea, I know that a nice built 350 can hold probably anything I'm gonna throw at it, I just wasn't for sure the price difference and weight difference between the 350 and the 400. I just knew that the 400 could handle about anything and was cheaper to build but I'll compare them closer when I can get a bunch of info on both to compare. If the difference is only $100-$200 then that's not that much more so that's resonable. I'm just getting as much info as I can to compare them.

 

Well guys, drove in 3rd today to just see what kinda rpm's I would be running on the highway. I am normally running around 2000rpm's at 60 and in 3rd I was running around 2800rpm's. I have 3.42's in the rear. Does this seem about normal?

 

Yep. I run 2800-3000 rpms on highway normally, around the 57-64mph range. It kind of keeps me from speeding as much in a way.....until the hammer drops

 

That's not bad.. My M6 with the 4.10's in 4ht, at 65 is about 3500. I'm going Th400 this spring, mainly because I only put about 1500 milesa year on my car or less, and 1/2 of that is going to the track. Once I get it on a trailer, the mileage will be about 1/2 that. I am going to go with a hughes th400 RMVB with t-brake, and a big hughes n/a stall, probably 4800. Probably be a little loud on the street.. but at the track, it will probably cut 1.5x 60 foot times with my 3600 raceweight car ( might be lighter by then though) ans see low 11's to high 10's.

 

when you are comparing an a4 to a a3...make sure you arent in lockup when driving in 3rd as you normally wont be buying a lockup th400/350. Mine with 3.23 gears..26" tires and th-400 runs about 3150 rpms for 70mph ....2800 stall

 

Glad to see that's about the RPM's, not too high. I don't drive much on the highway. I've been doing some research on the lockup, non-lockup tranny's but don't really know what guys are running on the 350/400 tranny's so could someone explain what the major difference is and what most guys run?

 

I'm putting a TH-400 in my car. My tranny guy told me that since my car will be around 3600 lbs or so with me in it, that a trans brake could trash my 12 bolt.

 

since your car is so heavy you might consider deeper ratios for your trans.

 

have a shop build you a 4l60e that way if it breaks its under their warranty.

 

If you want to keep your 4L60E then find a good reputable transmission man and buy the 4L60E rebuild kit from TCI with the HD clutches/steels, and get the HD Drum, the Billet servos, a deep trans pan, and a Manual Valvebody from TransGo... It will hold up to 500+ rwhp/10 sec 1/4 mile passes and you can keep your OD and still shift it manually.

If you plan to go hardcore and dont want to spend $3k on a transmission then build a TH350 or TH400.. Can't go wrong with either of them if they are built right..

 

4L60E is for the street (300-500hp). The big factor for the street is the overdrive in the 4L60E. The TH400's are for the strip (500-1000hp). Where does yours fit in?

 

Maybe for a stock transmission. I've seen built 4L60Es behind engines with way more power than that.

 

This is true for a stock 4L60E. I just rebuilt my 4L60E for the street with parts that can handle 650hp. How much money do you have? We can build a 4L60E that can take 850hp.
