Hey am i wierd in thinking my odom catches gears without flaring so high when i have a full tank of gas. but as soon as my gas is low or even at the half way point of Full/Empty i get the wierd flaring again..


Has anyone experienced this or made an observation of this before?

Anyone might know a solution?

 

Your 'odom'?

Unless you've got some sort of weird electrical problem going on, a tank of gas isn't going to change a trans issue.

When's the last time you had the trans serviced? How's the fluid look?

 

the fluid is at perfect level and nice and pink. actually it looks exact compared to fluid fresh out of a bottle.

I know I'm not going crazy, it seems to flair abnormally only when I'm 3/4ths or less on gas.

tranny looks fine. every mech i take it to seems to say the tranny is fine.

I also get a weird sputter if i stay at a steady 1500 so i try and drive at 1600 and i also can not pass 2000rpm's. I have to floor the gas just to get to 2500/3000 and even then its a very slow take off/gearshift

i also recently got my belts changed which fixed a problem i had with my dome lights dimming whenever i started up my car or pressed 2 window switches at the same time etc..

I'm not imagining this at all man

could it be electrical?
if so hows the proper way of diagnosing this or any recommended places i should take her to and get her checked out on the electrical stuff?

any other suggestions on a possible cause for this weird problem?

 

MAF

 

May I ask what "flaring" is? I've never heard that term in this context.

 

 

I believe its the buttons you have to wear on ones self. I think you are required to have a minimum of 20 pieces, otherwise your a slacker.

 

Ahhh. Office Space. Not bad.

 

check your maf sensor. very common issue with our cars.



flaring is when the rps flare due to the transmission not catching. its almost as if you put your car into neutral and then shifted it back into drive.

 

Thanks.

 

MAF or what else?

i think i may have an electrical or computer prob as well in the car. is there a way to re-wire the important stuff under the engine bay?

re-wire without a grounding kit just straight swap old wires for better newer ones?

and while im at it with that i might as well replace my ecu or is it called tcu?

 

Are you aware of just how many wires are in the engine control harness?

You have both an ECU and a TCM, which are you talking about?

That's a lot of work and money.

 

sorry for my lack of complexity when it comes to cars...

uh, whichever one may be causing the flaring. would the ecu do that? tcu?

no i have no idea how many wires are under the hood lol

 

Shift flare could be the TCM, or it could just be a bad trans.

There are hundreds. It would take a ridiculous amount of time to rewire everything. Not to mention you're more than likely going to run into a problem or two afterwards.

If you wanted to rewire the 'engine harness' of, say, a '57 Chevy, it would take you all of an hour.

 

thanks for the quick response pmohr

so would you think regrounding would be a better solution, if lets say i do have a wire going bad somewhere causing the electrical problem /inturn causing the flare? or should i just go straight for the tcm?

trans is kinda new i had it 'swapped' before, thinking it might have been the tranny causing the weird flaring but with the new one it was exactly the same, so i kinda ruled out the tranny being at fault.

 

There are some issues with the 5th gen TCM, search on it.

 

so look for what in the forum?

ill give it a shot

thanks pmohr for the help though bro i trust what i may have to do now

any tcm tsb's avail. on the 5th gen or is it an undocumented common problem?

 

matter fact. after looking up prices, this MAF replacement seems to be the cheaper solution and recommended twice, so ill give this a shot and then if not go for tcm?'

however i feel its definitely electrical and not mech. cause car consistently keeps running great and not many codes to work with...actually no codes. but i do experience dimming of certain lights in certain situations and stuff like that..so..

any tsb's for the tcm problem on 5th gens?

 

You have double checked your battery connections? The cables can become corroded making for bad connections as well.

 

any CEL's? the MAF is most likely the only being able to rev up to 3k problem. replace that first and maybe it will take care of your tranny issues. if not my next step would be to check/clean/replace grounds and if neither of those fixed everything its time to look at the TCM

 

yea VQ i unscrewed them the other day to take off my amp's but the power and odd shifting still felt the same.

so could it be something further down the electrical-line ?

 

hey feldman

no CEL's at all which is why im so mind boggled my car should warn me of these things.

but im looking to replace the MAF this week and then the wiring (btw know anyone good with checking/cleaning or replacing grounding wires in nyc lol)?

feldman those were actually the steps i though of taking in my head but then i though id just do the smallest (MAF) and jump to the biggest (TCM) which might not havbe been a smart idea if it were the wiring... lol

 

also is there a way for testing if my TCM is bad?

for instance would the tcm screw up gear shifts in PARK just as much as it would in D or is there a machine the mechs. hook up to check the tcm out?
