98 teg auto
 

I have serched and read every thread i could find on boosting with automatic trans. I have also read every thread on chipping ecus to work with auto trans and TCU/TCM. Found tons of useful information but nothing specific enough to satify my curiousity so i am going to come out and ask. Before anyone says "manual swap" I will tell you now that I cant afford to unless someone wants to come off some parts for next to nothing or trade for sexual favors from my slutty girlfriend.

Car: 1998 integra GS, b18b, auto trans

this is what I found so far

Car is obd2, i read that it has p75 ecu, obd2 ecus cant be chipped, need to convert to obd1, chipped manual ecus seem to work with external TCU/TCM.

Questions

What all needs to be changed for obd conversion? Obvious enough, the ecu. But dizzy? alternator?
Can I keep the TCU/TCM that I have now or do i have to find one from obd1 vehicle?
Am I better off just rocking the FMU, missing link setup thats collecting dust in the garage?

Someone just spoon feed me goddammit.

Not slutty enough without nudes!!! Check out the hybrid/engine management section. And have fun with that auto trans. But I have found places that make shift kits for them.

Re: 98 teg auto
 

all you need to convert to OBD1 is OBD2-A to OBD1 ecu harness and an OBD1 ecu. Nothing under the hood needs to be touched for the conversion. I know nothing about honda auto transmissions but whatever you do not run FMU + Missing link. Convert to obd1 and run a chipped ecu at least + bigger injectors for boost.

Buy your harness here:

b series 5 lbs blow ya trans

Re: 98 teg auto
 

Well...i guess i will find out. Blown trans is incentive enough to find $$$ for a swap.

Nude pics are required

Re: 98 teg auto
 

More pics of the gf, and I'll actually sit down and sift the factory wiring diagrams and tell you how involved it is for your year/model.

this may help you, it's an accord but it's probably close though

Excuse me, I'm the only angry ----------er allowed in this forum. A little attitude is great, this is HMT, but this is also a technical forum so let's try and keep things more or less on track.

FWIW, the Honda automatics are supposed to be strong, but they don't run enough fluid pressure which is why they like to die. Bump the pressures, deal with hard shifts, and it'll hold a bit of power.

Re: 98 teg auto
 

And how do you raise the pressure oh mighty JD

Re: 98 teg auto
 

Never done it on a Honda, but there are a thousand writeups on how to do it from domestics to the semi-popular Toyota units (the truck guys run the same base trans as IS300, and have a lot more DIY trans tech, FYI).

I figure a transmission pressure diagram and some common sense could do wonders, you might want to see if you can find a writeup on auto trans theory for a TH350/400 before you take a crack at it tho.

Re: 98 teg auto
 

Every time I've seen someone work on an auto trans (domestic or import), they almost always change/remove the springs from the shift accumulators, and very little else. They're basicly springs that dampen pressure (mostly for shifts), and most people replace them with solid cylinders of steel/aluminum. The problem is nobody really works with them. I know a FEW people do, but none here. Maybe MistaBone knows someone.

Besides that, a trans oil cooler will help more than almost anything. NOTHING will save an overheated auto trans, unless you piss pure liquid nitrogen. The stock rad's cooler will only get you to 150F at the lowest (with no load), but a huge front-mounted unit can get you more than halfway to ambient, even with a heavy load.

Re: 98 teg auto
 

The rule of thumb when shimming accumulators (the most popular method of increasing pressure) is to compress the spring, measure the total compressed height, and shim it, not to exceed 1/3 of the total compressed spring height. Works on damn near everything.

Automatics arent voodoo people. Suspension is, however.... :l

Re: 98 teg auto
 

Suspension is easy. Automagics are mysterious. :l

Re: 98 teg auto
 

Ill take that as you suggesting that the french dont surrender at the first opportunity. Fail. :l

Re: 98 teg auto
 

so if it's 2" static, and 1" compressed, don't exceed 1/3 of the compressed height with the shim aka 1.33?

Re: 98 teg auto
 

Last time I checked 1/3 of 2" wasnt 1.33 :l

Re: 98 teg auto
 

you said compressed height, i even quoted it.

Re: 98 teg auto
 

Yeah, compressed height of a spring is 2", 1/3 of that isnt 1.33" :1

Re: 98 teg auto
 

the compressed height of the 2" spring is 1". you said don't exceed 1/3 of the compressed height.

Re: 98 teg auto
 

I was pretty drunk last night, but your still not understanding I think.

If the compressed height of the spring is 1", 1/3 of that is .3334" which is the height you should not exceed with the shim for a 2" uncompressed spring. Blah.

2"spring means >.3334" shim.

Re: 98 teg auto
 

so whatever the spring compresses to is 3x the shim height, basically

Re: 98 teg auto
 

Oh, sweet jesu. :S

Re: 98 teg auto
 

if im not mistaken the shims cause a harsher shift getting rid of that clutch slippage the factory uses to make the shift feel smoother, which may provide some extra life to the trans. As far as raising pressures if i remember correctly its usually through the gasket for the valve body changing the orifices that are located for the shift valves, which u can usually buy gaskets modified for such a purpose. I have never teared into a honda *auto* trans tho :1

Re: 98 teg auto
 

Your half right. Accumulators are act as the cushion for the shift and as a pressure bypass. Valve body clearance (gasket thickness) only deals with orifice size/shape and really only affects pressure on that circuit.

Shimming or stalling the accumulators increases clutch holding pressure and reduces shift time, which reduces heat our enemy in the automatic tranny.

Long story short, barring the unavoidable physical weaknesses in the bands, sprags and sunshell, the more pressure we run and the more heat we remove from the fluid the more torque capacity we gain.

Re: 98 teg auto
 

Soft shifting/low fluid pressure is the #1 reason why Honda transmission self destruct.

Re: 98 teg auto
 

to throw 2 pennies in... some people use the amsoil atf instead of honda atfz1 and seems to help. most honda auto trannies fail once you boil the fluid. can be because you our a cheap ass or a vag and don't know crap lol. a quick search on bobistheoilguy.com forum can provide you with users of the amsoil atf in hondas

Re: 98 teg auto
 

---- your 2 pennies nig nig. Everyone else is talking about fluid pressure, not temp. This is HMT, we are all cheap asses. I know "crap" fag, check out bobisb20xsguyfrienduptheass.com. I'm too drunk for this ----.

Is it wrong for a noob like me to call this retard a noob?

------- retard :1

Re: 98 teg auto
 

Amsoil is the exact same ---- you can buy at the toyota dealership for their factory transmissions. Nothing special about it. Just clean synthetic ATF.

Amsoil = money racket.

Did you not read any of this post?

It's not beyond me to say ---- off to you too sir. haha.
Mr. Harris, you have pm

Re: 98 teg auto
 

automatics suck if you don't do fluid changes regularly, some do 15k intervals and if you add anymore power then what they are piss poor rated for they die. some use a inline filter and even honda went to this on the new models in and or around 03. the new oddssey has a filter inside the tranny that is easy to change. add a cooler, you could probably find one on any honda/acura with a hitch in a junkyard.

Wow no actual clutch plates, metals have friction material. No wonder they ------- fail. :1
