Transmission Question

[GREG]

I have a 1995.5 Taco with a 2.7 and 5 speed with 264xxx miles on it. Motor and tans have never been touched. I got it from a buddy of mine and he never even changed the timing chain.
My question is,
I'm starting to have issues with the trans and was wondering if the trans from a 2.7 can be swapped for one from a 3.4? Or are there a bunch of issues?
Thanks in advance,
Greg

No.

^^^ No cant do it, not campatable... 2.7 transmissions are w59, 3.4 are R150(F).

Find a w59.

[GREG]

OK, thank you!
Guess I have to keep looking for a W59 locally!

You all need to get your info straight. It can be done, but you need the right combo of bell housing and trans to mate properly.

Marlin used to make a bell housing for this type of application. Now you need to find a newer R155F bell housing.

See this post from Big Mike on the Marlin board-

This just solves the mating issues. Mounting and driveshaft mods may be required depending on several factors.

So the easy answer is to just get another W59 trans. It will be far easier and way less expensive to go this route. They are very strong and reliable.

Hey fuckstick, I got my shit together. Remember we're in newbie tech...

[ShowStop]

Wut?

[GREG]

Ok. Thanks.
I have no doubt about their reliability as mine has over 246000mi on it.
I'm just having a hard time finding locally at a descent price. I found one from a 6 cyl for $150.

The V6 models are far easier to find. I recently purchased a W59 trans and transfer for $150, which I considered a really good deal. Just gotta keep looking.

Just to throw this out there - If you are looking to swap out auto transmissions, you can swap the A340 series trans between the 2.7 and 3.4 (Watch for year-to-year compatability) - But just like ShowStop mentioned, you'd need to swap bellhousings and torque converters. And may have some issues with the placement of the dipstick/filler tube.

Now, back to reading up in CV axle replacement

try searching for a trans on www.car-part.com . I recommend filling with Red Line MT90 or similar GL-4 synthetic gear oil and replacing the shifter socket and seat with new ones from marlin crawler. Makes it shift like butter

Thank you ShowStop, you are spot on Sir!

The V6 transmission (R150F) is about an inch longer than the 4cyl transmission (W59), so this will require modifications to the cross member mount and/or cross member, as well as possibly the rear drive line. I don't recall off hand, but I believe both t/cases are the same length (I'll need to go measure them to be sure).

I definitely agree with ShowStop on this. The W-series is a good transmission (it was even used behind a 2.8-liter inline six cylinder), it is lighter and has a slightly lower 1st gear (3.95 vs 3.83) so it will do better off road. You could take advantage of the taller overdrive of the 6-cylidner (0.838:1 vs 0.850:1) but looking at our old Vehicle Speed Calculator, it's only gonna net about a 40 RPM engine speed difference on the highway.

My opinion is to keep it original & keep the 4-cyl trans in there. As for finding a good used W59 transmission, have you tried Jeff @ Toy Connection (near San Jose, CA - (408) 988-4040) or tried searching wrecking yard databases such as www.car-part.com?

If all else fails, we rebuild em and make them bomb proof with a bunch of heavy duty upgrades http://www.marlincrawler.com/transmi...t-complete/w59



Best of luck!

Thanks Mike.
If I weren't 3000 miles away from you, I'd consider bringing it to you.
There is also the fact that I have well over 240000miles on it and I only paid $500 for it last year. So I can't see myself spending thousands on it.
Slowly but surely I'd like to make it worthy but I have to start with the necessities first.
I have checked carparts.com and everything is pretty pricy for the mileage here in Canada

[BigMike]

Ahhhhhhhh Canada. I wonder if you guys have a Canadian version of car-part.com, or equivalent??

Yes we do. I'm on there all the time. Like I said, anything with somewhat descent mileage is @$500-1000!

[ChrisTRD1]

Might as well go to a local trans shop and buy a rebuild for that price. Side note, the timing chains on the 2.7L's are considered lifetime parts and only need to be replaced when they start making noise, which should be upwards of 300k

Glad to hear that. They are starting to make a little noise now, but with the mileage I have on it, not sure if it's worth opening up???

[ChrisTRD1]

Are you sure it's not an exhaust leak from the manifold? They are notorious for cracking and will make a ticking sound that would sound similar to a chain. If you need to replace it, get a used exhaust manifold from a 2001-2004 tacoma. They changed from cast iron to a tubular steel style that won't crack, and it's a direct fit.

Check your manifold for a hairline crack right between the two middle runners, that's how mine gave out

Thanks for the info Chris. I will check that out this weekend when I get home.
