Hello!

Does anyone have actual knowledge relative to any differences between the various T-5 Z transmissions that are sold new? Respectfully, I'm not looking for any speculation or "I think....," I'm looking for actual first-hand knowledge.

For example, Jeg's lists a "McLeod" Tremec T-5Z for $1,895.

McLeod Tremec 1352-000-251 T-5 5-Speed Transmission Ford 5.0L | JEGS

and the Ford Performance T-5Z for $1,995

Ford Performance M-7003-Z: Heavy Duty T5 Transmission 5 Speed | JEGS

They appear to be identical with the only difference being a $100 price difference. The part/SKU number for the "McLeod" Tremec that they list is the same exact number of the one that MDL references in their listing.

TREMEC Super-Duty T5 5-Speed Transmission Overdrive 1352-0251 2.95 first .63 OD - Modern Driveline

Odd right? Or are there actual differences? I find it hard to believe that McLeod is buying Tremec T-5s and putting their name on them and charging $100 less than Ford, but maybe that's the case?

Figured I'd call Jeg's to see if a tech there would know and they said that McLeod makes the gear set in the T-5 Z for Tremec so McLeod can sell that tranny under their name and charge whatever pricing they want. Can anyone back that up?

I doubt you’re going to find anyone who has first hand experience with all 3 of those, but judging how the listing for the t5 from modern driveline lists the ford pn as an alternate, I’d say those are the same. Well hell, I’d say they’re all the same.

The only places I know of to get an actual built t5, as in different than they come from tremec, is from Astro or pro-motion power train.

I'm in the "all the same" camp. As far as I know, only Tremec is making new T-5's and the only one they still make is the T-5Z.

I do not believe McLeod makes transmission gearsets. They are more known for clutch/flywheel and then reselling trans from other vendors (Tremec). I'd buy whichever one offers the better warranty, which from a quick look looks like 1 year for both. If that's true, get the cheaper one.

Tremec makes all of the new T5z 5 speeds, many companies sell them as "their" own brand.

With that being said I build T5s and sell them from stock 3.35 WC T5s to T5z with upgrades and when gear sets are available the G-Force and Astro A5 T5.

I pulled the trigger on the "McLeod" T5Z so I'll confirm back relative to packaging, etc. once it arrives in the event anyone else has this same question or is curious as to any differences.

They're all the same. Just sold through different names. If you plan beating on this thing hard i would recommend installing an upgraded countershaft thrust plate, billet shift keys and shiiming it tight. The thrust plate will keep the gear contact patch even under load and stop the rear countershaft race from spinning, chewing into the case.
 
#11 ·
Where/who is the best source for the billet shift keys? Tony at Astro? I just ordered a "T-5 World Class Upgraded Cluster Support Plate" from Astro. Are particular spec on the tight shimming?

No, at least not during the warranty period. The car that this tranny is going in sees like 2,000 street miles a year... it's just a cruise night, car show, spirited Sunday driver rig.

Ya know....All these years in the performance world and these guys weren't top of my mind (kinda forgot about them). I miss MM&FF, kept all the various vendors (that advertised) top of mind. ProMotion would have been a good option had I remembered them. For the intended use of the Jeg's sourced T5Z, a brand spanking new tranny from Tremec should suffice.

Will certainly keep ProMotion in mind for the future!

Was able to get the "McLeod" T5Z to my door for $1,800+ tax ("free shipping") through Jeg's with $100 off code. Can't complain about that price! I've seen them for $2100-$2200+ elsewhere.

I don't have plans to thrash the T5Z, just wanted a nice, new tranny with a 2.95 1st all fresh and new for street cruising and the occasional strip pass or road course event. After the warranty expires, I will likely do the reinforcements that 408foureye mentioned for good measure.

Thanks for the guidance 408foureye. Mobil 1 synthetic ATF is readily available so I'll go with that. When I spoke with MDL, they said to stay away from Royal Purple as it's too slick and will cause issues with the T5Z. They sell Amsoil ATF and said any good GM Dexron III ATF would be good. I believe I've been running GM Dexron III in my original '86 T5.

I just checked the website, and it's actually down at the moment.

Phone number used to be (866) 253-0019.

Seeing the same, hopefully just temporary.

That's the same phone number on the PayPal receipt that I have. I'll give it until the end of the week to see if there is a status change with the order.

The new gearset t5z is a good piece. I can’t comment on the differences between McLeod and tremec units. I do have the exact unit that 408foureye is talking about. Brand new T5z gearset with billet cluster support plate, billet 3/4 keys and all steel bearing retainer. Just finished and ready. Along with 4 other T5s. I am located just west of York PA. PM me for more details

Also to further expound on Astro, from my understanding the company we know as Astro Performance Transmissions is ramping down to be closed. Been in progress for quite some time. So if you have any issues with parts from Astro I can help anyway I can as the "mother ship", if you will, is still going strong on the Astro front. Also its worth mentioning here that the A5 gearsets will no longer be available, when they are gone, they are gone (if they are not gone already).

Hey, Jason. Thanks for the information and sad to hear at the same time. Tony and Astro was like a legend in this realm!

At this point, with any orders that were placed with Astro in the previous days, would you recommend taking action to get money back asap? Only $85 but I placed an order for a cluster support plate and a clutch fork via the Astro website (PayPal) and I'm guessing it won't be fulfilled?
 
#24 ·
That's a shame. For years I've wanted to pick up an A5 gearset and was getting to the point of being ready to order a set once I heard some feedback on the new TKX.

Guess that closes that door.

Okay... You asked for someone with knowledge to chip in...

Tremec only makes one T5Z:
Some are tagged 1352-249 and were sold through Ford Motorsport and the rest are tagged 1352-251. They are identical other than some subtle changes through the years.
Some of the larger Elite Distributors put their name on them and thus the list of different names.
A 1352-251 is a 1352-251. They all come off the same assembly line.

While I think about it, many sellers advertise the T5Z as the 1993 COBRA T-5. The Z and the COBRA T-5 have the same upgraded parts like the front input pocket bearing and steel front retainer, but the COBRA T-5 is a 3.35 first gear T-5 with a 0.68 fifth gear and the T5Z is a 2.95 first gear T-5 with a 0.63 fifth gear. A direct replacement, but NOT THE SAME TRANSMISSION.

Price differences:
Tremec sets the Minimum Retail Price, "Retail Floor Price" for the T5Z. For 2020 the minimum price was 1,895.00. For 2021 the Retail Floor Price for the T5Z is 1,950.00. Anyone advertising the T5Z for less stands to lose their authorization to sell Tremec Transmissions. With the release of the new TKX, the TKO no longer appears on any Tremec 2021 price sheet that I have seen.

Astro Performance Warehouse:
The spiral with APW started long before COVID. While I consider myself to be a very close friend of Tony's, I find his virtual disappearance to be puzzling, Communication with him has pretty much stopped for me too...
There is another company at the SAME ADDRESS in Tavares, FL as "Astro Performance Warehouse" called "Astro Transmission Parts". This is Tony's Father's business, Glenn Sarvis. His business is still going strong. No issues. Unfortunately, "ATP" can't make good on problems with "APW". "ATP" always was the major supplier of parts for "APW" including the A-5 transmission gears. "ATP" is still making the A-5 gears and building A-5 transmissions. There are none available at the moment, but more gears are being made as I type. We will see some in a couple more months I am told. I expect that Tony will eventually turn the APW business over to Glenn but that can be difficult. I would prefer that Tony reappear and get back into the game.

500 HP T-5:
I don't care what anyone says. You can't build a T-5 that launches at 500 HP unless it has the Astro A-5 gears or the G-Force Street gears in it and probably the 9310 alloy main shaft upgrade. You won't get a transmission with either of these gear sets for the same price as a new T5Z. Be careful with expectations. There are companies that over rate transmissions just to get the sale.

Thank you, this is super helpful.

My 1352-251 T5Z arrived today and the tail shaft was hanging outside of the box and there are head size holes in just about every side of the box... guess it had a very rough ride with FedEx. Looks like FedEx repackaged it as it's not in the factory box (box is about 3x the size of a standard Tremec box wrapped in 24lb shipping paper) so it must have been through a small war at some point if the original box was completely destroyed. Not gonna even attempt to keep this one.... Anyway, called Jeg's and they already have another one on the way and have FedEx picking up the war story tranny tomorrow. From what I could see through one of the gapping holes in the box, the 1352-251 is 100% identical to a friends "M-7003-Z" 1352-249 that he recently received, except his came in the actual, undamaged Tremec box without a war story!

Yes, the "Z" in the "M-7003-Z" number is the "Z" that causes it to be called a T5Z.

The factory box generally makes it through one UPS/FedEx ground shipping!
They throw those boxes around in handling and the bracing internally is just cardboard. Once the bracing gives way the transmission just flops around in the box. It costs more, but the best way to ship is by Freight, strapped to an open pallet! Freight carriers always use a fork lift and they don't get abused in shipping. Surprising enough, even when they arrive like yours did they are rarely damaged, but you won't know if the input shaft took a hard hit until you install it and the transmission whines all the time... Glad they are taking care of you!
