The allison is taken out of duramax trucks and 47-48re's are put in for dragstrip use. Why? The allison is a clutch to clutch transmission and has to ramp up one clutch as it ramps another down. It can't shift 5 times in 10 seconds without destroying itself. Funny, they don't put 4l80e's in 6000...

No disrespect taken. I was on a rant there and did not mean to single you out. However, didn't you find it strange that this 25 trans vet did not know the 48re had a 5.0:1 ratio lever? Is it his first one? Neither you or him could figure out why the frt clutch was cooked. I simply gave you the...

Did your "trans tech" ever maybe think that the 5.0 lever was part of the cause of frt clutch failure? If not, you should probably take your truck elsewhere because he hasn't learned much since 1983. One more time for everybody. 1) The gm conversion is fixing a symptom, not a cause. 2) The 5.0...

clearance hello, dhawk here. rear clutch factory says .025-.045 I would stay between .025-.032. This will keep the belleville spring from bending too far when applied. This is especially true if it has the .072 thick belleville. frt clutch factory says throw across the room and it should be...

The downshift clunk as we have referred to it over the last few years from the 48re is totally normal and it will now hurt anything. It is simply the change chrysler made to the boost circuit of the 48re valve body. the 47re's did not do it. What they did was change the boost circuit and and frt...

You took a cheap shot at me stinker by telling a member that you wouldn't buy what I thought would work. I took a cheap shot back and for that I'm sorry. I don't know you as a person so I don't really have an opinion. The fact of the matter is though, I've gotten one transmission from a member...

This is the one part where I am still poss wrong. The new electronics are just new chrysler gov solenoid and transducer. I still believe transmission debris is the root cause of this. I was a dealership technician (easy fellas) before I started my business. I watched the 318-360 half ton...

48re No, not really. I sell the special servo spring to you guys. Also blocking the controlled load portion of the frt servo is a massive help. I hesitate to say these things in the open forum because of competition but oh well. Poss using the servo piston out of a 46-47 or diesel 48 would help...

48re The 48re in the qc srt-10's was interesting to say the least. It was fun to see more of chrysler's trying to do something a little different and causing even more problems. I had heard the v/b had a different spring for the limit valve in the part-throttle kickdown assembly, this turned...

OK, 250 PASSES OR SO IT NEEDS THE INPUT SHAFT REPLACED. USUALLY THE CLUTCHES ARE FINE. WE HAVEN'T GOT TO 500 PASSES YET BUT YOUR RIGHT IT WILL PROBABLY NEED TO BE REFRESHED WITH SEALS AND POSS FRT OR POSS REAR CLUTCHES. HAVEN'T GOT THAT FAR YET. MIGHT NEVER GET THERE HE IS SICK OF REPLACING...

ACTUALLY THERE ALREADY IS. UNFORTUNATELY, TRANS-GO SHIFT KITS AND DEEP PANS ARE NOT GOING TO DO IT. 1378HP AND 2500 LB/FT TO BE EXACT. YES IT IS BEHIND A DIESEL BUT IT DOES SPIN 5200 RPMS. IT WEIGHS 8300 LBS, HE HAS PULLED 15,000/LBS WITH IT AND HAS RUN LOW 11'S IN 4WD. HOWEVER YOU ARE RIGHT...

THE 4.2 LEVER IS AN EXCELLENT START. THERE ARE A COUPLE OF MORE PIECES THAT HELP IT EVEN MORE ESPECIALLY IF YOU HAVE THE TRANS OUT. THE TRANS-GO SHIFT KIT WOULD BE FOR MILD TRUCKS. IF ANYONE DOES USE THE KIT, DO NOT USE THE MANUAL VALVE SUPPLIED, USE THE STOCK GOLD COLORED PIECE, OTHERWISE...

FOR SOME IT MAY BE A VALVE BODY AND SOME OTHER PIECES TO GET RID OF SOME 2-3 OVERLAP. FOR HIGH HORSEPOWER IT MAY TAKE A CONVERTER, AN INPUT SHAFT OR WHOLE TRANSMISSION. IF SOME OF YOU CAN ACTUALLY MAKE 1500 HORSEPOWER IT IS GOING TO COST SOME MONEY. IT WILL BE AN INDIVIDUAL THING I THINK...

I DON'T KNOW WHAT YOU MEAN BY RAMP UP SLOWLY. LINE PRESSURE, LINE RISE, PUMP VOLUME? THE 48RE OR 47RE OR TORQUEFLITE WAS NOT DESIGNED FOR DIESELS. IT WAS DESIGNED IN THE LATE 50'S. IT WAS PUT BEHIND THE CUMMINS IN LATE 1988. I GUESS WHAT I'M SAYING IS EVERYBODY IN THE WORLD WANTS TO PUT BETTER...

HELLO, MY NAME IS DUSTY HAWK FROM HTSTRANSMISSIONS. THE 48RE IS AN EXCELLENT TRANSMISISON, HOWEVER, WHEN CHRYSLER CHANGED FROM THE 47RE TO THE 48RE THEY CHANGED SOME THINGS THAT ARE NOT GOOD FOR HI-PERF USE. 1) THEY WENT FROM A 3.8 TO A 5.0 SHIFT LEVER WHICH CAUSES 2-3 BINDUP AND ALSO THE...
