Engine/Transmission (1998.5 - 2002) 47 re ???

[MTate]

My transmission has 140,000 still shifts good and doesn't slip . That I know of It pulls 9,000# descent . I'm getting ready to go for the H/P . Would it prolong the life it? Or do me any good to go for a T/C and V/B upgrade or wait to do the whole thing when it goes out ? I'm slowly going to get above 450 but it will take a bit of time . Another thing how do you attach the truck profile below without typing it .

Anyone with a 47re truck who has done any mods? Will somebody help this guy out... . I'm a little lost on what they will & will not hold. Atleast I got ya back on top.

I have an Edge EZ which only increased the total engine HP to somewhere about 275 to 280. It was very noticable and I lost my TC within about 20 K pulling a 13K 5th wheel and daily driving. The transmission had 90K on it a the time. When researching power increases all product reps stated that the transmission, exhaust and gauges needed to be dealt with first.

Gauges first, then fuel.



For that power level, just save up and do the trans right the first time. Won't waste your time or money on the extra R&R to just a T/C and V/B, and them have pull it again later when it goes out. Could trash the new parts at the same time.

MTate,

At 140,000 miles I would give you the advise to have one of the major transmission vendors go completely through your trans or get an exchange from them. If your truck only had 30,000 to 40,000 miles I think you could get away with only a T/C and valve body, depending on how much power you're going to add. Coming from a heavy equip. service dept. back ground I have learned that there is only so much life built into components, bearings, clutches, plates, etc... When my truck only had 13,000 miles on it, I put an Edge EZ on it and shortly after I started to feel a slight shudder when the T/C went into lock up on a hard acceleration. Also when I installed the EZ I didn't feel much difference until lock up because the the factory T/C efficiency is so lousy. The points I'm trying to make is at 140,000 miles, the trans. has a lot of wear in it and if your going to add power to your engine you're going to stress an already marginal trans "47RE", plus you won't feel a lot of the power until you get a better T/C in it. The only other recommendation is to try and find a reputable vendor/installer that is familiar with the trans of choice to do the rebuild/install. I went up to Abbotsford B. C. and had DTT themselves do my complete trans and it has been the best upgrade I've done to my truck. I wish you luck with your decision.

Regards, Mike.

Looks like I got some thinking to do . I'll probably just spend the money on these rusty doors.

Thank's
