93 rx7, auto., 63000 on car, 8000 on new tranny, gutted dp, and bo valve, thats it, problem: when i drive in D, without hold button engaged, (im flooring it the whole time, from start) , i get to third gear, and it will not shift to 4th (it does this about 80 % of the time), i redline it, and let off, and then if i let it drop all the way back down to idle rpm's, around 1000, it will then shift about 50% of the time, i have no idea what is wrong, and i have did searches, but i would appreciate any info on this, thanks,
paul

 

would someone give ur opinion, so i can get this figured out, yall are giving this wonderful website a bad rep, give knowledge, dont be lazy!!!! u can do it!!! whoooo!!!! yeahhh!!!!

 

check your ATF fluid level while the engine is running

 

I had a similar problem but it would just not shift in D , I had to use the hold button. It ended up being the ECU. I would advice to sheck that to see if it ir working correctly. Did it do this when you got the tranny if so they most of forgot something?

 

Did you check for error codes??

 

If you need a ECU,I have a 93 auto ECU with reciept to prove it's only ben in my car for about year and half.I doing the auto to manual converion.

 

Get a 5-speed

 

hello all, well skunks, i love ur advice, i will try checking, which i have but that dipstick is screwed up, long story, well jalers, i will consider ur opinion, that is great advice, well cihuuy, there is no check engine light coming on, so, but thanks anyway, SILVERFLASH2, HOW MUCH FOR THAT ECU? BE FAIR, OR NO SALE! I KNOW U WILL! and finally ijneb, thanks for the most irrelevant peice of information i could every possibly desire to receive on this forum, UR THE MAN!

cihuuy, please reread what u wrote me and tell me again, thanks,

 

sori dude... was late when i wrote it... hehehe let me explain it in simple words...

this i experience myself... i didnt have any check engine light one... but i knew my car was not normal coz my car was limping... so i diagnose my self wiv wiring the ten and the groud together to check for error codes... but NOTHING! i when to the Mazda dealer and borrow their diagnose computer... got three different error codes!!!
