OT Mechanics: Standard transmission issue
Posted on 8/25/24 at 9:10 pm
Posted on 8/25/24 at 9:10 pm
Recently purchased a 1997 Isuzu Hombre with a 4 cyl engine and a 5 speed standard transmission.
Transmission is hard to shift especially into reverse and 2nd gear.
I am thinking the synchronizers are bad in the transmission.
I am looking at 3 options:
1. Find a used transmission(which I think is not a good idea, most will be wore out as well),
2. Purchase a reman transmission.
3. Rebuild it with a kit. I am a decent parts changer but nothing special.
I am not 100% sure what type transmission it is. I think it may be a T5 by Borg Warner.
The stick shift is on the floor and transmission has a clutch slave cylinder and a clutch master cylinder.
Weighing as whether to get a reman transmission, or rebuild it, or pull the trans and get a transmission shop to rebuild it for me.
I have not priced out a reman yet and looking to see how much a transmission shop could rebuild it.
How hard is to rebuild this transmission? Do I need any special tools?
TIA

if you do any work on it, be sure to change all motor mounts and transmission mounts. most people overlook this and wind up right back where they started.
you are better off driving it a while longer. some depends on what you use it for. if not daily, might not do anything.

Try a fluid change with some Pennzoil Synchromesh

As others have said try syncromesh or Redline MTL.
I had a 1989 Integra that had a grind between 1 and 2 (due to my abuse over the years) and the Redline MTL damn near fixed it.
I did end up rebuilding with a kit years later and replacing all of the bearings and synchronizers and putting in a taller 5th gear from an Accord that made the car handle 80 mph on the interstate without turning 4k rpm.
It's not a terrible job but you have to pay attention and having a good (preferably factory) service manual is a must.
Hope this helps.

Shift into 1st then reverse. Rev out first and skip 2nd

No way I would rebuild it myself….I would imagine there as\re alll kinds of tricks and special tools involved in that. I would pull the transmission myself and take it to a transmission shop to be rebuilt

Possibly could be the shifter mechanism. Outside the transmission. May just need some new bushings or such. I had a Toyota truck lose the "shift gate" when some shifter bushings wore out. Also the comment about the fluid is probably a valid one. Find on Google a forum for that vehicle. They may have a fluid recipe for a tired transmission that fixes some issues.

Each to his own but manual transmissions are shockingly simple inside.
Aside from bering pullers and such generally no special tools.
You do have to watch out for washer placement and orientation and you do have to shim the overall gearset clearance inside the housing.
But overall very straightforward.

Your transmission does not have “ bad synchronizer’s”. Whatever that is. 
Your clutch needs work. Check your master and slave cylinder make sure they aren’t leaking or bad. You may need to change the clutch. ( clutch disc, friction plate and throw out bearing ,). Research it. You can do it.
In all likelihood your transmission is fine. You just need a clutch.

If you have to ask you are not the person who can successfully diagnose and repair a manual transmission. Quit thinking you can hack or outsmart this issue. Get it repaired correctly by a qualified professional who has ASE certification in Manual Transmissions and Transaxles.

This. The modern feminist woman always exposes herself at the first available opportunity. Anything that needs male expertise should be shamed, insulted, and guilted. Car repairs are one of the last remaining spaces in public life where a modern feminist woman cannot replace an actual man with her man the government. The government will do everything but deposit jizz in your muff and fix your car.

I have a high mileage VW and a few new plastic shifter bushings corrected mine which started having difficulty going into first and second gear.
The bushings also took alot of the slop out of the shift mechanism and tightened it up, more definite engagements into each gear. You get used to it being worn out and don't notice over time until its fixed.

Or a new pilot bearing. I used to have an S10 which the Hombre is just a re-badge of. Pilot bearing went out and started making shifts hard. Warning sign was a loud rubbing noise shifting into gear from a standstill. Also it makes it difficult to shift into 1st or reverse from park.
I'd bring it to a mechanic and have them pull the transmission and examine the slave cylinder which is inside the bell housing, have them examine the pilot bearing and look the clutch. Odds are its one of those three.

The first thing I would do is a triple drain and fill. Drain all the fluid that will come out then replace it, drive it at least 10 minutes making sure you go through all the gears and into reverse each time then repeat the drain/fill/drive 2 more times. The amount of transmission issues that are just dirty fluid is significant.
I would start with 10 quarts of fluid on hand, that will do a triple on most transmissions but you will know if you need more after the first refill. Also make sure you have a funnel that will allow you to refill it or some manual transmissions need a fluid pump to fill them. My point is ensure you have the proper stuff to refill before you drain.

This would be my first check. Replace and use the fluids prebiously mentioned.
Hopefully this is external of the trans and not internal. Makes the job a hell of a lot easier

Lol you sound like my old boss Henry Lamonica RIP. Run up a bunch of ATF money before you even check to see if the fluid is too low or too high.

The cheapest option is for you to pull it yourself and replace it with a rebuild. You will still have to change/resurface the flywheel and install a new clutch. The Isuzu usually has a slave cylinder type throwout bearing that is designed to be replaced. A rebuild will have all new seals and a new slave cylinder/throwout bearing. I would replace the u joints in the drive shaft at the same time and check for excessive wear if your transmission mount is bad.
Good luck

I’ve rebuilt my Muncie a few times and I have spent probably the exact same in tools and time that a shop would charge overall.
Expect to need bearing pullers, a press, and a transmission jack of some sort for you to do it right.
My Muncie does have synchros and straight cut gears, but the PO just used ATF fluid instead of the correct GL fluid. I rebuilt it with the same parts, noted no major damage, put good GL-4 in it and it ran great.
Maybe you get lucky and have a similar experience.
