I was just wondering what all the 48re owners out there are running (Boxes, Chips, etc...) and having no problems out of their stock trannies... I have been doing loooots of research on how these 48re's are holding up with performance. i have the 2003 SO (250/460) any others with identical truck with mods?
Thanks
Eric

 

2003 QC LWB 4x4 555 HO CTD. Edge EZ Box set on 60hp/200TQ. Its been on the truck for 60,000 miles +/- a couple hundred. Tranny has held up fine. its been through 15,000# of trailers, and hard accelleration and the tranny doesnt mind it

Lately though, when you are under WOT accelleration, the tranny will slip into 4th gear. under normal accelleration, the tranny has no hard shifting or slippage

 

Read my sig.I tow A 37 foot car trailer and hammer the snot out of it and the only thing that I did was toast the turbo by being stupid and turning off the egt limiter at the track and pouring to much fuel at it.23000 miles and it had a box on it from day one.no problems out of the trans as of yet!!

 

I have a volumizer box. Been running it for around 17K miles and no problems at all.

 

katoiler at what temp did you toast the turbo?

 

Edge EZ on #4 setting, never had any tranny trouble. I just now upgraded the tranny, see sig, but it had noting to do with box. The stock tranny was fine running the Edge (roughly 10,000 miles with NO codes), just plan on bigger HP#'s in the near future.

About 1800 deg.lucky I did not fry a piston or two!It broke the shaft at the exhaust side and put the parts in the head pipe.Nothing in the intake side!

 

Could be wrong but I thought the SO had the 47RE?

 

starting it jan 1, 03 they came out with 48re, my truck has a build date of jan 18, 03
