JET Trannies

I wanted to know if anyone has any info about the JET performance tranny? I have a 97 with a 4L60E and as expected, it is going out at 55,000 miles. I was thinking of getting one of the jet performance tranies, does anyone have any history with these units? I'm leary of going with a regular rebuild on mine because I don't want to be in the same boat again in another 50,000 miles or so. If I did go with a regular rebuild, does anyone have any good tips or perfomance mods to mention that I should do? I'm looking to get it done this week since I'm on vacation. Thanks in advance to any solutions.

Re: JET Trannies

The JET Tranny comes with the improved valve body kit. Best thing to do is talk to Paul over there 714-848-4200. He got my truck setup tight and cheaper then i was quoted elsewhere.

Re: JET Trannies

Well, I got a shop who knows the jet trannies and is going to build mine the same way. I had talked to Jet, but it was going to be at least 10 days before I would even get the tranny. This shop will modify the valve body and pretty much do all the same things that Jet does, but it is going to cost me much less. They are also going to put in a large aux. cooler, along with the shift kit, extra clutchs,corvette servo piston,kevlar band,stanless sprag, etc etc. And hey, they even gave me a Fire Dept. discount....lol...how could I refuse. Plus they are going to set my shift points for my 33's.....and to top it off, it will be done by thursday. It will have a 15 month or 15,000 mile warr. so I think it ought to work out good. Hopefully this will be my first and last trouble with my 4L60E.

Re: JET Trannies

TxFireman,

If it works out for you, post the shop on here. Might be someothers in your area looking for a good deal.

make sure they pressure test it before they put it in (run on trans dyno) lots of cheesy places don't and the waranty doesn't mean crap if you have to keep bringing it back in.

Re: JET Trannies

I will post when I get the truck back and let the results be known.....yes, they are going to dyno test the unit as well, in fact, they said they would actually run all sorts of tests on the tranny through the trucks computer before they even take it out to work on it. I made sure I was going to get it done right....and grilled the guy for about an hour or so before choosing that shop.

Re: JET Trannies

Well, I have had the truck back about 4 days or so now and everything seems to be great. I'm happy with the tranny work and it does shift firmer than it did stock. I'm supposed to go back in a couple of weeks for a follow up check. They are going to check for leaks and run a scan on the computer to make sure there are no problems. The name of the shop I used is High Tech Transmission, they are in San Antonio Tx, the cost for the removale, rebuild with extra heavy duty trans cooler, kevlar bands, corvette servo piston, shift kit, extra clutchs in the 3-4, valve body mods etc etc, re-install, dyno tested, shift points adjusted, 15 month/ 15,000 mile warr. is going to cost you right at 1,840 bucks. The build up took about 3 days. Hope this helps anyone who needs it in this area. RC

Re: JET Trannies

YYYYYYIIIIIIIIKKKKKKKKKEEEEEEESSSS!!!!! that is expensive for what you had done. i had the exact same stuff done plus a stronger torque converter and it was only 800 bucks. of course, i bought the parts myself and had them put them in but still that is very, very steap.

Re: JET Trannies

Yes, I should have mentioned that mine came with an improved torque converter. Actually, I would not even beging to think of rebuilding any tranny without replacing the TC, it would just be asking for trouble in my opinion. Oh,.....and pardon me for not buying your story of paying 800 for rebuilding a 96 or newer electronically controlled 4L60E transmission with the afore mention upgrades. And if it's not that exact trans., you are not compairing apples with apples. RC
