Snoop's Take

The OTC 1521A is a low-lift transmission jack designed to securely lift heavy transmissions for repair and maintenance tasks. With a 1000 lbs capacity and features like a universal mounting head and safety chains, it provides stability and versatility in any automotive shop environment. Consumer feedback reveals a divided sentiment; many appreciate its effectiveness in lifting heavy transmissions, while others raise concerns about its sturdiness and clarity of instructions. One user stated, "What I'm getting from this is 'Do not trust this tool with anything insurance can't replace.'" Additionally, some users reported issues with a bent jack, expressing frustration with statements like, "this bent POS trans jack makes me want to quit my job." Overall, while the OTC 1521A demonstrates strong lifting capabilities for heavy automotive components, the concerns regarding its durability and confusing manual suggest potential buyers should consider these factors before purchase. Therefore, it's recommended to weigh the pros and cons carefully when looking for a reliable transmission jack.

Jack is bent and not sturdy

Any particular model in mind?
Sure you might be able to weld it but do you want to be under the car if that weld fails?

Core Power Plays

The specs and strengths that make it shine.
Preference for larger capacity jacks
I am always of the opinion you get the biggest you can afford.
I’ve heard nothing but reports of this being a problem.
Thank you for posting to AskMechanics, No-Cost-2353! If you are asking a question please make sur
General discussion about the vehicle and tools
Anyone have any experience with this transmission jack?
It's just a bigger Miata with a frunk.
For what you are doing its probably fine.
So far this advice has worked well for me but is there really any truth to it?
General discussion about hydraulic jacks
Hydraulic Jack won’t raise anymore than a couple inches.
Importance of using the correct hydraulic oil in jacks
Did I just mess up my jack? Kind of got excited and didn't realize I would need hydraulic oil when I purchased it.
Yes. It’s very important to use hydraulic oil in a hydraulic jack.
I use 3 in 1 oil for salad dressing - I doubt it will hurt the jack.
General discussion about jack oil and alternatives
But I've used regular motor oil. Didn't hurt a thing.
There’s nothing in a jack that 3 in 1 will fuck up.

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.
Discussion about alternative jacks
I work for a transmission shop and every one of our stores uses HJT-1000's.
Working with a cheap, bent jack is fucked.

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Discussion about vehicle maintenance and tools
makes all manner of lifting just a little more complicated.
Discussion about personal preferences for tool brands
If I'm getting under the car I want to trust what I have holding it.
Honestly, I avoid Harbor Freight for most tools.
I’m not as keen on spending for every little thing to be top grade.
Daytona is the premium brand of harbor freight.
Discussion about the price of jacks
I hate using the stock jacks.
It's average, if not a little high.
I love my craftsman aluminum race jack.
Harbor freight has them for around 80 I believe, and there's nothing wrong with harbor freight tools for the most part.
Comparisons between different brands' CVTs
It's pretty smart.
THAT cvt transmission is bad.

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Concerns about the stability of lighter jacks
the 450lb scissor jack (not enough stability, drops quickly instead of lowering safely, etc) and recommended springing for the 800lb.
It’s convenient cuz it’s pretty light and easy to scoot around.
That scissor Jack one is a worthless piece of shit unless you only need it a couple of times.
Never FLUSH old transmission fluid, draining and refilling is less dangerous.
General skepticism about the smaller jack's effectiveness
I don't recommend unless highly skilled, but it still works to this day!
Thank you for posting to AskMechanics, jstar77! If you are asking a question please make sure to
They are a friend's dad's that he was given and I don't want to anything silly to happen while I rot
Importance of jack stands for safety
ALWAYS USE JACKSTANDS!!!! My cousin was working on a 4 wheel drive sitting under it... when they fell and the truck fell on him and broke his back.
PSA: Jackstands save lives... It's so cheap and easy, don't risk your life because you're too cheap/lazy to use jackstands.
This is why scissor jacks are called widowmakers.
**Jacks are for lifting, and lifting only.** PERIOD.
Concerns about the risks of using jacks
Theoretically could cut out the kink with those copper pipe cutters and run some rubber hose between the two ends with clamps on both ends, though I definitely wouldn’t recommend it as a permanent fix.
Concerns about jack stands and safety
Harbor Freight is great for what it is, I just don't ever see myself jacking up a 4ton vehicle on any of their jacks.
General skepticism about the effectiveness of jacks
Are they're Jack's a good purchase or a just get better one ?
I mean it gets the job done either way but the Daytona jacks come with a 2 year warranty.
Maybe because he enjoys working on his car??
Concerns about safety when using jacks without support
do yourself a favor and get some stands too. Jacks are for lifting only, and it's never safe to work under something that isn't otherwise supported.
Discussion about the quality of jack and potential issues
Jack works after I tried it out.
General tool safety discussions
Excellent, stay safe out there
General skepticism about lighter jacks
if no kit is available. pass might be the option..
so far it's holding up great.
Make wooden block lifters its cheaper, just take 2x6 and cut different lengths and angles in the ends.
They perform fantastically when new.
Discussion about reliability of CVT transmissions
I hear it’s super expensive for a new one, and when I look at Altima reviews biggest complaint by far is CVT failure- are they really that bad?
Nissan/JATCO CVTs probably have the highest failure rate of any CVT (or any transmission) on the market.
the cliche saying they don't make them like they used to is sadly starting to apply more and more to Honda.
