Some people burn up transmissions, some people don't.

On a side note, I have a friend that when he tows I feel sorry for his transmission... Kinda hard to say something so I just cringe until I have to say something . You don't have to drop 2 gears up every overpass and gas it like it's unloaded from every stop light. Driving through houston the transmission has to change gears 1000 times

 

How many times has it been serviced?

last service was 35k on tranny going in next week to get another.
its had an easy life 100 mile round trip to work on interstate and no trailering till the last month.

 

i am shocked it lasted a month. i think i am gonna drive it till it wont go n e more. but still keep it serviced and not bomb it, just drive it like i have. (easy)

 

wow a lot of myth out there about the 2 trannys. like stated not many hard parts were changed to make it stronger. the lock up stage was sped up by opening up a bleed off passage in the separator plate in the vb. same could be had by drilling a .080 hole above the switch valve(small valve behind the retainer), in the valve body itself. disassemble 46re and 48 re and you will see what I am refering too. they opened the plate allowing the fluid to bleed off faster so the converter locks up faster. what do I know I only built vb's for chrysler about 7 years. longer life of the shaft may be contributed to have it peened by an outside vendor. they were cut the same that is for sure.

 

Since you know that (and I know that), how about posting the 48RE specifics over the 47 from a 'official' DCX standpoint incl -

increased capacity direct clutch drum

3@ 6 pinion planetaries

increased capacity sun gear shell

increased capacity overdrive clutch

ect.....................

So, yeah - what do you know that we don't, eh?

 

df57,

Do you have oversize tires?

Nick

 

I can not get engineering to give me a number so I will not for sure. official never. dcx is now history the offcial statement would be chryslers stand point.

 

Not bashing but...that's a little cynical. Others have had somewhat decent results with the 47RE even:

BRayls - I merely meant for you to post any upgrades and improvements besides the ones you and I have already listed - anything else that makes the 48RE better and more reliable than the 47R series - excluding the all electric valve body, of course.

 

i have 35's now for 20k miles before that was 285's

 

Could be the tires.

Nick

 

The VB is not all electric on the 48RE. Shifting is till the same old hydraulic type as 47.
