e40d

[mean97]

in my 97 i have a e40d that is built with all kindas of goodies. the guy that built it said it should be good for up to 600 hp no problem. well im starting to get to that mark on the power side and my trans is acting a lil funny. when i get on it and im in 1st it will launch real hard just like it should then it takes about 2 secounds for it to shift into 2nd and when it does it slams into gear so hard it will just smoke the back tires. now that might all sound like fun but its not. but whats werid is when im just driving around town it shifts fine.... now what could this be? if someone already asked about the samething i just did im sorry but i could not find anything

Did you have the tuner before the trans rebuild? If you did and did not have it reburned you could have pressure issues. Unless you have the tune burned for trans upgrades most will include programming that will raise trans pressure, shift points, etc, etc. Assuming the builder installed a shift kit or reprogramming kit of some sort; that is already raising the trans pressure, now you are adding to it with the tuner. Do you have a trans temp gauge, if so what is the temp at? If not, why?

Also, are you sure the trans is good for 600HP? I spent just over $5k rebuilding mine with the best parts available; all steel planets, 4140 input shaft, BW clutches, Sonnax updates, high flow pump, custom valve body, Tugger kit, 5 disc billet TC, etc. and I doubt that is good to 600HP... The TC is, but the trans???

the trans cost me about $5500 and its top doller! and i have a trans gauge and its staying cool. my tuning is for my trans and my mods for the tranny. its only messing up going into 2nd gear

Take it to someone that has a Snap On scanner or AutoE and have them check the pressure and solenoid function. Could be that 2nd gear is drilled to big on your shift kit or an issue with the valve body.

What code are you getting? It could be the cause or atleast a factor.

im sorry to tell you this but for that kind of money i would be taking it back to the builder i just had my 4r100 rebuilt witch they are about the same internals and it cost me 3000 and it will hold 600 hp with 40 inch tires and 373 gears its got blue plate clutchs kolen steels billet converter and a bunch of valve work so i just thought i would let you know what i would do

i took it to the builder and he looked at it and changed the atf he said everything was fine. i was right there and there was no shavings or clutch dust.
