My new 1996 Z26

That's a typical 4t60e shift screw up and signs of an aged valve body. All that controls the trans is mph and throttle position at part throttle shifts, wot there are mph vs tp kickdown values and there are wot rpm and mph shift points.

[beretta]

Could it possibly be the TPS ? how does the kick down on the 4 speed work in these cars ? is it vacuum ? i see no TV cable hooked to the throttle linkage.

So the 2nd gear miss shifting is a common problem ? could it be fixed by swapping out the valve body ?

It shifts fine and smooth other wise, only unless im right to the boards on the throttle and only sometimes it does that...

First time it done it was the other day i was turning a corner and got on it to keep up with my buddy in the A4. and when it did it, it was bouncing off the red line and then a back fire sound out the TB then kicked into gear and threw me back in my seat LOL. sounded pretty cool but i imagine its not great for the trans haha.

If its a valve body issue, changing the fluids is not going to solve it ?throw some lucas in there ? ill just keep my foot out of it when im in 2nd gear..

Two things, you were taking a corner left or right? turning left the fluid will go away from the filter and cause it to loose trans pressure... Its good to run these 1/2 to a quart over full to prevent that issue. Also its a bit more involved than just "replacing the valve body" I wouldn't take a part a 4t60e without doing a full rebuild on it. Also as I said these kick down and shift controlled by RPM/MPH and TPS readings, its ALL ELECTRONIC hence the E at the end of the name. The Vac modulator is ONLY for varying the pressure used to make the shifts... When there is no vac it's running at full pressure to shift a bit quicker, obviously stock is still very slow, but it's meant as a comfort deal.

Ok well i was turning right.. but i will check the fluid level and maybe add 1/2 qt over full with some lucas. normal driving is not an issue, this trans can prob last for a long time if i keep my foot out of it. it has 258,000 KM on it. not really into changing the trans just yet only had the car for 3 weeks or so. i would swap to a 5 speed but my gf loves driving the car and shes not good with manual, she wont even drive the 88 the last couple days i have had the Z and left the keys for the 88 and it hasnt moved, i had her driving it before for a couple days but she wont even touch it now and she didnt do bad at all. So im kinda stuck with leaving the auto in there at least for now haha.

Nothing wrong with an auto if it's built right, mine chirps second gear.

[beretta]

well mines not built just stock, and it does chirp in 2nd too, even more so when it miss shifts and jams into gear but is only once in 100 times it does it.

Passed pollution test with ease.. the limit one 1 thing was 200, hit 46. limit on something else was 1.00 it hit .04 all readings were super low.

Will have it fully plated by friday, will be sitting for the week since i have to wait for my insurance lady to get everything ready for me, been driving with 10 day permits and can only get 2 of them 2nd one runs out today

It was funny when i went into the store to do the paper work and give them my keys, i told the girl where it was parked and shes like i guarantee its the only beretta in the parking lot im sure the guys will find it, i said its probably the only one in the whole town lol. i forgot to mention i have 2 of them now.

I have passed 1 Z26 a couple times going to work and i found where they live, its right in town where i work, drove by and seen it sitting there the other day, its pretty beat up looking but has the Z rims. front lips screwed and filler panel is broken, im going to knock on the door and see if i can sell them some parts, maybe trade something for those rims i kinda like the GTZ rims on my car though.

Not bad for a $500 car, went right through safety and flew through pollution test.

[Money pit Beretta]

That's great!

so im getting a 3400 from my cousin out of an 03 grand am with just under 100k KM on it. he said the intake gaskets have been done in it recently. he had the trans too but he paid alot for the combo and i dont need the trans too.

What all is needed to make it run in my 96.. Swap the 3100 injectors into it and change crank sensor ? is there a specific crank sensor i need.

Ive read a few different topics on this but theres alot of people doing the swap from a 3.1 in older cars and such.

The engine im getting is from a 03 grand am.. and going into my 96.. so essentially i will have all the fuel lines, egr stuff and things from the existing 3100 engine, ect. i read somewhere you need the 3100 power steering pump..

Im just trying to make a list in my head of what all i need to do this..

1. My throttle body is from a 3400 already and swapped the throttle linkage and everything functioning on my car now. so i can just swap that over to the new 3400.

2. Fuel injectors.. not sure what i need to do here.. keep the 3400 ones in the engine or put the 3100 ones into the 3400.

3. power steering pump i can leave attached to the car.

4. AC compressor... will this bolt from the 3100 directly to the 3400 so i dont have to disconnect my lines since it works Amazing i can leave attached to the car.

5. different top rad hose.

6.. wiring / fuel lines ect, will be used from the 3100.

7.. Down pipe, i maybe able to grab a short section from my friend left over from a van engine swap.

8..... Is my 96 trans going to hold up to that 3400.

My cousin has the engine and trans from the 03 grand am.. would that trans bolt directly into the beretta ? and be any stronger then the existing one ? He wants $400 for the motor.. and another $400 with the trans.. just trying to save some cash here, i know im paying too much already since i would have just bought a beat up car or van for 600 or less and scrapped the remanding of it and got 3-400 back over the scales. my cousin paid 800 for motor and trans, and its readily available to me just sitting there waiting to be dropped into something, has under 100K km on it. my friend had a venture van trany sitting beside his garage and has been away at the hospital with his kid for the last 3 weeks and someone took it away with a 3400 block and frame attached, would the venture van tanys bolt into the beretta? do they share the same type of axle where they go into the trans ect ?

[2.2H8TA]

In my opinion, if you pay $800 bucks, for a motor and trans, with only 62k on it. (converted to miles). Thats a great deal, should be able to get a good amount of life out of it still. The venture van motor and trans, are probably beat, considering they have more miles, and have been hauling around a minivan for them all. You'd probably spend the money you got for scrapping the van on rebuilding the motor, and then some. Unless you are planning on a rebuild either way.

[woody90gtz]

Use your existing Beretta trans with the 3400. Use your 3100 fuel injectors and all sensors & accessories. Everything will bolt in just like stock basically, and the computer will control it as if it was stock, but add some fuel for the added displacement. I ran a 95 like that for years.

[beretta]

i read somewhere that in 03 the 3400 got different injectors then previous years and splicing my harness into that injector harness and running the ones in the engine. but maybe that wont work with my stock ecm.

Do i need a different crank sensor??
Will the AC compressor from the 3100 bolt onto the 3400.

Basically i should be able to pull my engine out and drop the 3400 right back into place and have it running the same day ? thats what my plan is anyways. i will probably drop the frame and struts and all and lift the car up will be so much easier to pull the engine off the trans and sit the other one into place, slide it back under the car and bolt it back in, be alot nicer to get to the lower bolts and what not with the whole thing on the ground then try and lay under the car and dink around to put bolts in..

I would not try to pull the engine separate cuz it will prob be a tight fit and a pain to get back down and onto the trans, if i drop the whole thing out the bottom i wont even have to pull my axles or mess around too much, i have a couple block and tackles at the shop so lifting and moving things around will be simple.

Wont be for a couple weeks, but when i get the engine id like to start it on a friday night or saturday morning and have it done by saturday night and driving, so anything extra i will need would like to get my list together now.

Well i sanded around the wheel wells and done a quick back yard paint job to cover up the ugly chipping paint. eventually im going to repaint the whole car. just a few quick shots, i still have to wet sand it but was waiting for a couple days until the paint cured some, and havent been home until 7 ish every night this week from work and been out fishing and doing other things half the night, i need to find time this weekend to get that done. looks better then flaking paint though lol.

[NMBeretta]

not to bad

[beretta]

would have been better... the paint i sprayed bubbled out around where the old primer was, i sanded it by hand up so far past where it started chipping. i used acrylic duplicolour paint. must be real crappy primer, i had painted 1 rear side previous and wet sanded, while i was doing the rest last weekend i re painted that one too and it bubbled, so i ended up sanding right back down to bare metal and starting over. i didnt use primer just painted it, since i will be doing the whole car before next spring. i just wanted to get this covered up before it rust's. once i wet sand you can barley tell its been painted around there, other then the white is a slight shade brighter but barley noticeable. it does its purpose to keep it from rusting didnt do it to make it look Mint.

And what a job to get it into the back yard LOL, my lane way is just wide enough between the house and the neighbors fence to fit and i had to 50 point turn it to get it back there. was pretty breezy that day as any other day i was going to try and paint it and was a little less breezy back there. notice my boat back there, i put it there with the riding mower. its a tight fit but i made it.
