Default 3.42 without Stall

Does anyone have a A4 with 3.42 rear with a standard stall?

Seems I probably need a new TC and I am doing my 2.73/3.42 diff swap at the same time. Looking to possibly save $500 by not buying a performace TC.

Will a new stock TC really suck that bad with a 3.42 rear?

I can get a delco reman TC for $200 at cost.

a TCI will cost me probably 6 hundo.

Please advise.

Will it hurt performance...No.. it will drive a little faster than a stock auto due to the gear swap.

Is a TC worth the money for a higer stall...Hell yes

If you are trying to save money, i understand... but you could probably buy a used stock verter on this board for 20-40 dollars, free if you want to pick it up.

What happend to the converter it had in it?

I didn't put a stall in mine and did the 342 swap. I don't drag race (from a light anyway.. hehehe) much. I doubt I will ever put a stall in it.

Default see my other post

I have another post in this section that outlines my convertor issues. I think mine might be going out.

Is it possible to have a convertor that is going out without having an engine code?

What are the symptoms of a convertor going out?

Todd, so you have no stall huh?

Imagine if you dont have a stall you dont know the difference, huh?

How did you reprogram your shift points?

Hptuners. I didn't change my shift points, only shift pressure for a little crisper shift. Once you tell the pcm you have 342s, it shifts normal.
I've had race(ing) cars for 20+ years. I know what a stall can do, just not in this vette. For drag racing (on/off the track) it's great, but doesn't suit my needs for the vette.

If have 3.42 gears on A4 with stock stall.

You will need to adjust your shift points because of the gear changes or you might hit rev limiter at WOT.

I have a baby cam on a 98 C5 A4 (221 @ 114) and don't have a stall converter---I' sure it would be faster with one and it is someimes difficult to hold at a stop because the brakes won't hold at the higher required idle(900).But I've gotten used to it and it works fine--I'm sure at some point I will install one but it is drivable without one.

yes. or get a preditor hand held unit. Hypertech (at least the older ones) didn't have a setting for 342s, only up to 315s. The handheld units are limited though and cost almost the same as just buying HPtuners.

When you swap the 342s, and before you can flash the ecm, you MUST drive in 3rd. If you put it in OD, your tranny will go into "limp" mode and shift like a sledge hammer. very disturbing to say the least.

If you were going to spend $200, at least spend $450 for a yank stealth 2800 or 3000. Very Mild.

Getting 3.42 gears without a converter is like getting a cake without frosting. DONT DO IT.

not if it's already apart. If you're going to buy a converter anyway, get a 2800-3000 as suggested before. You won't notice a ton of difference and it will help the gettyup n go.
$600 is the standard price for dropping a tranny and/or rear end.

I had a mail order tune done for $25 plus postage both ways and it is working great with the stock converter. It is my wifes toy and it drivers perfect with the 3.42. Unless you are willing to live with the higher stall I would leave the stock converter in.

I put a set of 3.42 gears in with no Stall. I don't drag race the car at all and was not looking for all out performance. The reason I didn't install a Stall is because I didn't want the added heat and transmission slippage that comes along with it. Don't get me wrong, for all out performance at a drag strip I would have went with a Stall, but for a car used mainly for cruising and pleasure it isn't worth it too me. Going from 2.73 to 3.42 without a Stall was exactly the extra acceleration I was looking for.

C'mon in the C5 for sale section you see high performance converters all the time. Typically people swap them out for even high stalls. I would go that route. Putting a stock one back in is a waste.

I use HP tuner software. Go to the speedometer section and put in the gear ratio you are running and bingo! While it does get the speedo right there are a lot of other things that use the MPH to calculate such as shift point tables.
