    Torque Converter Recommendation

    The powertrain has to work as one holistic system, where cam grind, converter stall, final drive ratio, transmission ratios, tire size and vehicle weight (along with intended application/use) must all be taken into account and phased in/matched so that the system functions optimally...

    best rear gears for 700r4

    3.23 to 3.73.m with stock diameter tires. What's your current ratio? Had a customer with 2.73s in a vette where we did a 700r4 swap from a th350 and he would slip/fall out of OD when trying to accelerate while in 4th. Upgraded to 3.42 and problems went away. How many miles on the trans? What...

    Torque Converter Recommendation

    Yep, this - wanted him to confirm but if his final drive is really 3.07, hes going to be yanking out that trans to replace the 3-4 pack nearly as often as he does engine oil changes...I ran 4.56 in my K5, up from 3.73 and made a noticable difference with my 35s...

    Torque Converter Recommendation

    Standard TMBX replacement from GM will work. Your final drive ratio is 3.07?

    Turbo 350 (TH350) Information Thread

    Hi Everyone, Figured I'd start an all-encompassing TH350 Transmission thread, similar to my 700R4 thread, to serve as another repository for information about these transmissions. Covers servicing, rebuilding, parts selection and performance/heavy duty upgrades for your TH350. This should be...

    Trying to determine what converter I’ll need

    Lol, Do you need one built?

    Trying to determine what converter I’ll need

    They're great transmissions. Up to 700 hp street/strip the only major hard part upgrade I typically do is a billet, rollerized fwd clutch hub (and sometimes a 97+ 4L80E direct drum for its 34-element intermediate sprag). Have you considered a Gear Vendors unit for OD?

    Trying to determine what converter I’ll need

    All those parts they're installing great but you can likely have a local builder build you the same or better transmission using your unit for a good deal less. Plus he'd be local to you so if it needs to go back to him under warranty, you dont have to worry about shipping. Re that 700r4 in the...

    700R4 no forward gears that fixed itself ???

    You're welcome...these transmissions are fairly easy to rebuild as long as you follow proper procedure..I'm going to update the OP in that thread w/all the special tools you'll need later today or tomorrow so you'll know what sort of tools you will need to rebuild it yourself, should you decide...

    700R4 no forward gears that fixed itself ???

    Yes, agreed - that would have absolutely sucked if you broke down while on your trip - glad it didn't shiit the bed then, haha. The amount of time you have left before it becomes inoperable impossible to predict. I'd drop the pan to see what, if anything at the bottom and if you see any pieces...

    700R4 no forward gears that fixed itself ???

    Sounds like the beginnings of gear train failure or possibly input sprag failure. Id drop the pan to confirm or deny the presense of gear teeth if it happens again or if you temporarily "neutralize" at surface street or highway speeds.

    700R4 Information Thread

    Hi @SirRobyn0, I rebuild GM, Ford and Dodge transmissions and have plenty of time w/the '40 series' units (42RH, 46RH/RE, 47RE, 48RE) so feel free to PM me later...I most likely won't be able to respond until tomorrow morning but will take a look and get back with you then.

    700R4 Information Thread

    Agreed...between the C6, TH400 and 700R4, you basically have a preponderance of longitudinal transmissions manufactured between 1964 and 2013 pretty much covered across all of GM, Ford and Dodge vehicles. If you were to also build a German ZF6HP26, you'd be very well prepared to take on any GM...

    Trying to determine what converter I’ll need

    The stock trans won't last too long unless you drive it like an 80-year old going to the grocery store. You will also need a converter with a much higher stall than stock. Contact the manufacturer of your cam to obtain guidance on stall speed range for the grind you'll be using. Depending on...

Please feel free to add your own tips, tricks and anything else that you found helpful or ask questions as you need to and I’ll respond as soon as...
